This article is one in a series that have been released in conjunction with Wayne's new book, 101 Performance Projects for Your Porsche Boxster. The book contains 312 pages of full color projects detailing everything from performance mods to changing your brake pads. With more than 950+ full-color glossy photos accompanying extensive step-by-step procedures, this book is required reading in any Boxster owner's collection. The book is currently available and in stock now. See The Official Book Website for more details.
Check out some other sample projects from the book:
The Boxster convertible top mechanism is used a lot, and is often exposed to a lot of stress and strain as a result. It's very likely that you will experience a problem with the opening or closing of your top somewhere along the line: knowing what to replace and fix is valuable information.
One of the first things I installed in my wife's Boxster was the SmartTop controller that allows you to open and close the roof with one-touch operation (see Pelican Technical Article: Smart Top Roof Control Installation). This is a neat feature, except that there are no safeguards built into the unit. So, if the top latch is not fully released and the roof catches on it as it is being automatically lowered, you can seriously damage your roof. In my case, I accidentally did this one day, and the resulting damage ended up including about 20 hours of work along with $1200 worth of parts (see the photos in this project). If you install one of those automatic controllers in your Boxster, just beware of the potential damage from the one-touch operation button.
When compared to other convertible cars (like the BMW 3-Series), I find the design of the Boxster roof to be relatively simple. A single motor connects to two cables and drives a leveraged gear mechanism that raises the rear of the roof, then raises the rear convertible lid, and then folds and tucks the top away. When your roof is not opening or closing correctly, then one or more of the components in the mechanism are probably worn out or damaged. Follow the photo array in this article to learn about each of these components and how to replace them.
The early-style convertible top transmissions have been replaced with a more reliable later-style one. This can be installed in place of the early one, but you need to also replace the standoffs with different ones specific to the late-style assembly.
This photo shows some of the parts that you might need to repair your convertible top. A- Convertible top motor (powers both left and right sides at the same time). B- Ball pivot pin (2 req) C- Control cable D- Improved transmission assembly (increases the leverage of the motor to lift the top), left and right required E- Control lever (attaches to the opposite side of the transmission assembly), 2 req F- Improved transmission assembly standoffs. These are required in order to bolt the transmission assembly in the same place that the old one fit, 2 req G- Switch to detect closed position of the top handle H- Bushing for convertible top push rod (item J), 2 req J: Convertible top push rod (pulls and pushes the top open and closed), 2 req
This photo shows tremendous destruction on the left side of the convertible top motor assembly. The blue arrow shows the red plastic ball socket for the top assembly that has completely broken away. This normally would connect a pivot ball pin that is located out of view near the green arrow. In addition, the mechanism for lifting the rear metal cover has completely sheared off as well. The pivot ball pin (shown in inset) would normally be attached to end of the control lever (yellow arrow), but due to the top getting stuck, it has been broken off. In this case, the top transmission, the lever, and the convertible top push rod needed to be replaced with new parts.
If your convertible top push rod has broken, then you will need to replace it with a new one. Unfortunately, at the time of this writing, a new plastic ball cup end is only available by purchasing an entirely new rod (about $75). When you get the new rod, line it up to the old one, and make sure that the two are exactly the same length. Alter the two adjustment points on the rod if necessary. To install the rod back onto the convertible top linkage, use a screwdriver wedged up inside the mechanism to obtain the necessary leverage to snap it on.
To remove the convertible top transmission, begin by removing the boomerang-shaped lever (left photo). Using a 19mm socket and a breaker bar, you should be able to loosen the bolt and remove it from the transmission. In this particular case, the lever arm had bent and the transmission had also broken. Pull back on the foam sound deadening material to reveal the convertible top transmission (right photo). Three nuts attached to standoffs hold the transmission in place.
This photo shows the various steps involved with removing the transmission and disconnecting the cable. A- With the three nuts removed, pull back on the transmission and separate it from the side of the car. B- Loosen up the four nuts on the backside of the transmission housing, but do not remove them. C- With enough slack in the mechanism, carefully pull out the cable. D- The green arrow shows one of the three standoffs that need to be replaced if you upgrade to the later-style convertible transmission. E- The later-style transmission allows you to simply snap the cable in place without removing any screws. F- Shown here is the replacement, later-style transmission installed in place with the new longer standoffs.
To disconnect the cable from the motor assembly at the rear of the compartment, simply remove the circlip (yellow arrow), and pull out the cable. Replacement of the motor and/or switch are fairly easy too: simply remove both cables, unplug the electrical connection, and unbolt the motor assembly. Unfortunately, at the time of this writing, the only way to replace this microswitch is to purchase the entire bracket assembly (about $130 from Porsche).
The factory manuals recommend using a drill to move the cables while aligning the left and right side, however, after repeatedly doing this many times, I discovered a short cut. If you disconnect one side of the cable to the motor, you can then press the roof up/down button for short bursts of time. This will move one side of the roof mechanism, but not the other side, allowing you to align one side with the other. For extensive movement of the convertible top transmission, I recommend using the cordless drill.
When all of your parts have been replaced, you need to align the left and right assemblies together. Keep in mind that if something broke on your roof, then you might have bent some of the tracks for the rear cover or other important components of the mechanism. In other words, you may not be able to get the top aligned completely perfectly. The goal is to get the lever arms on both sides in the same position at the same time. Measure the length from the lever arm to a reference point on the top of the car and compare it to the opposite side. Adjust one side of the mechanism by using the technique described in Photo 6 to match both the left and right side.
Comments: On my 2005 Boxster, the top is not properly aligned. I believe this is causing or contributing to the edges not falling into the guide channels every time and it looks like the picture here http://forums.pelicanparts.com/boxster-cayman-forum/560184-convertible-top-adjustment.html. I can't tell from this article and the pictures whether I need to disconnect the cables in order to us a drill to align the top or whether the end of the cable is accessible without disconnecting the cables from the motor assembly. Thanks!

Followup from the Pelican Staff: The cables are disconnected at the motor. The motor is located below the third brake light, attached to the interior body panel. Once disconnect, attach a drill as shown in this photo. - Nick at Pelican Parts
Comments: What brand of oil filters for the 1999 porsche boxster are recommended.
October 4, 2013
Followup from the Pelican Staff: I like the Porsche OEm filter or Hengst. Give our parts specialists a call at 1-888-280-7799. They can help you find the right filter.
Comments: Trying to reassemble mine after replacing the ball joints-all the pushrods removed. I noticed the passenger side larger pushrod is missing the c-clip in the metal ball joint. Trying to fabricate one now-not much luck with it.
Also, mine moves by the motor but doesn't seem to by using the drill-doing something wrong?
September 24, 2013
Followup from the Pelican Staff: I would try to locate a new clip.
If it doesn't move with the drill, the cables may not be engaged. You did state it moves with the motor? This sounds odd that it would with one but not the other. - Nick at Pelican Parts
Comments: I have a 2003 Boxster S. When lowering the top, the glass rear window does not fully drop into the recess. This causes the top to not lower fully. I can reach back, grab the window, and force it in a down position. Then the top will lower fully. I would appreciate any tips.
September 17, 2013
Followup from the Pelican Staff: If you can shove it down, the regulator is faulty. You may have to replace it. - Nick at Pelican Parts
Comments: Porsche boxster clam shell pulls further down when I try to open roof from closed position, if I jam a rag underneath clam or get someone to slightly lift it works fine, once completely open and lid is closed there is no problem in closing, it is just when roof is closed the clam shell pulls further down and jams solid, any helpers
September 17, 2013
Followup from the Pelican Staff: There are three adjustments for the clamshell. Try adjusting the plastic stops at the rear corners of the clamshell. There is also a plastic sliding adjuster toward the front. Pushing the two plastic parts together will raise the front of the clamshell on that side, pulling them apart will lower that side. The support arm has an adjustment too, but I would not touch that unless you have replaced parts.- Nick at Pelican Parts
Comments: Thanks Nick for your advise. May you tell me where the relay is located? I appreciate your help.
September 16, 2013
Followup from the Pelican Staff: It is located in the relay box above the driver footwell. See attached photo.- Nick at Pelican Parts
Comments: hi everyone! Currently I have a Boxster S year 2000. The convertible top open without any problem, but when I going to close the top, I have to pull it with my hand, until reach close to the service position. I verified the lift mechanism and looks like both transmissions are adequately working.
Does any one have had the same experience and can tell me what is the problem? It's seems that the electric motor doesn't have the power to lift the top.
Thanks for your help.
September 14, 2013
Followup from the Pelican Staff: I would check if the relay is failing under load. if it works with help, there may be an issue with the relay, not sending enough voltage. - Nick at Pelican Parts
Comments: i have a 2004 boxter soft top when top raises it is rubbing on roll bar it never did before how can this be adjusted the tops rubber grabs and holds it down i have to push top back to clear roll bar
September 9, 2013
Followup from the Pelican Staff: Check the mounting and hinge points of the top linkage arms. There may be an issue causing it to be out of alignment.
Check that the top tension cables are attached properly (by the folding part of the rear window area, cables run from the top down to a fixed joint.) - Nick at Pelican Parts
Comments: Can I mix a newer style transmission on one side with an older style on the other? In other words, are they the same gear ratio between new and old? Thank you!!
August 28, 2013
Followup from the Pelican Staff: No, I don't think so. To be sure, you can determine the part numbers of the items you want to use, if they do not, (the old side you want to replace with the newer part) then the answer is no. - Nick at Pelican Parts
Comments: Thanks for the article. My only question about the article is the mention of the later style transmissions. From what year is considered later?
My problem..... I began hearing a popping noise coming from the passengers side.
August 17, 2013
Followup from the Pelican Staff: if I remember correctly, the top was changed in 2003 models. - Nick at Pelican Parts
Comments: 98 boxster porsche trunk lid light in dash is on all the time. Micro switch is working. Also has power & ground. How do you turn of the dash light when trunk is closed?
August 17, 2013
Followup from the Pelican Staff: If the switch is working, the signal might not be getting all the way to the alarm control module. There may be a faulty wire. - Nick at Pelican Parts
Comments: Thank you for this forum. Are you at all familiar with an updated linkage adapter that is now made out of a different material? Is this available for purchase?
August 8, 2013
Followup from the Pelican Staff: Contact our parts specialist at 888-280-7799 and they'll help you get the parts you need - Kerry at Pelican Parts
Comments: @Pasiuk57 - This issue happens with my '97 with similarly low miles. Sometimes when I drive over a bump in the road the windows will roll down, as if I've pushed the latch release to put down the top. I have to repeatedly push open and close the latch several times then then windows will go up. We have also had issues with the top going out of sync according to the garage that attempted to repair and they think that may have something to do with this issue. Not sure. Have had so much trouble with our top. $$$
August 1, 2013
Followup from the Pelican Staff: Sounds to me like the latch closed indicator switch needs to be adjusted. The whole top may need to have the position switches adjusted so the control unit knows the correct position as the top opens and closes - Kerry at Pelican Parts
Comments: @Bill - "Is this why my driver's side flooded and required a new rear control unit?" Definitely could have been from that side of the top being loose. Also check the drains on either side inside the to make sure they're not plugged up - this happened and we had the same problem with an expensive repair.
August 1, 2013
Followup from the Pelican Staff: Thanks for helping one of our readers - Kerry at Pelican Parts
Comments: Can anyone tell me what they changed on the 2007 Boxster top? I am getting a dash message saying the "Convertible Top Ctrl Failed" and I get nothing when I push the roof switch to lower the top. The clamshell doesn't move nor does the roof. Is the message related to a switch on the clamshell? I've also got a fabric piece that sits below the back window. It is firmly attached on the passenger side but not on the driver's side. Is this why my driver's side flooded and required a new rear control unit? I believe this is another change for 2007 that instead of the anti-theft unit I have the rear control unit under the driver's seat. Any help would be appreciated!
July 28, 2013
Followup from the Pelican Staff: The soft top control unit has picked up a fault and you will need a scan tool to retrieve the fault code. You leak could be the loose fabric. - Kerry at Pelican Parts
Comments: I have a 1997, I cant remove the cable from the transmission end, its seem like the cable got stock in 1 inch way inside making the other ends of the motor cable short short 1 inch not to reach for it to turn, I have try to pull it off, but its wont get off, any ideal, or are there a part to replace the plastic part with the cable on the the transmission.
July 19, 2013
Followup from the Pelican Staff: Check step 5, if that doesn't help the cable may be jammed. Give our parts specialists a call at 1-888-280-7799. They can help you sort out what parts are available to repair your top. - Nick at Pelican Parts
Comments: This is a suggestion for as addition to the project 71 in the book 101 projects for your boxster. I had replace the pushrods for my top. I had always garaged my 1997 boxster until this year when I needed to rely on it as my daily driver. I had a severe water leak and during a torrential downpour my floors filled up with water and my security system malfunctioned and i was not able to start my car. Fortunately I was able to bale my car out without severe damage to my controls under the seatsair bag and security system. I found that when the pushrods for my top broke they ripped the liner in the top compartment. I was surprised that this is not mentioned in your bookI love the book. It looked like a major job to replace the liner so I repaired it with sealer and I believe my water leak problem is solved. I would like to save other boxster owners from possible damage and see the liner mentioned in your articles. Thank you for your great articles.

Followup from the Pelican Staff: Just disconnect the battery before you start any work and put every back together the same way it came apart. If you have to remove the clockspring make sure you keep it in the same position when you re-install it - Nick at Pelican Parts
Comments: 2000 Boxter S , after removing and completely disassembling the top to get the rear vinyl replaced I reassembled and everything went well except the two window cables that guide the canvass inside the frames always track outside the frames so I am putting the top up halfway and reaching out to finish guiding the cables inside the track and finish closing. Can't figure out why they no longer track to the inside.
June 24, 2013
Followup from the Pelican Staff: This can be caused by the velcro strap being misinstalled or worn out, the flat spring being worn out or the bracket for the cable binding. Start by inspecting the velcro strap, it should be tight on the black bar, but not too tight where it won't slide. You can check if the flat springs are worn out by removing and flipping them over, if the problem goes away, replace the springs. Last, the bracket for the cable could be binding, it should be able to pivot, if it does not, it could be screwed in too tight. - Nick at Pelican Parts
Comments: The lining of my 04 boxster has come out and hangs. I just need instructions to glue it back.
June 22, 2013
Followup from the Pelican Staff: There is no good option to reattach it. Usually the fix is replacing the headliner. - Nick at Pelican Parts
Comments: I have a 1998 Boxster. When I raised the roof up this morning, I heard a loud "crack, pause, crack pause, crack" sound from the mechanism as the roof was going up. The top made it 6" from the latch-point, and I was able to manually pull it the rest of the way and get it closed. I don't want to do any more damage to it assuiming that something's broken as opposed to just being misalinged. Two questions: 1 if I close the roof and something breaks, can I still manually lift the top to close it? 2 Any ideas on what's making the "crack" sound or how to fix it?
June 19, 2013
Followup from the Pelican Staff: It's hard for me to guess as to what is making the noise.
i can say, it may or may not open and close manually. Depedns on what is failing. If it jams, it obviously won't function at all. - Nick at Pelican Parts
Comments: Sir as u told me my top is allready open but know how to open the top cos when I am pressing the button voice is comming how to close a top???

Followup from the Pelican Staff: Not sure I understand your question. If you are trying to figure how to operate the top, check your owners manual. - Nick at Pelican Parts
Comments: I replaced the push rods for the top on my 1997 Boxster and everything is aligned properly but when I close the top and it reaches the very end where the cover is about to close it changes directions and starts to open. How do I syncronize the top so this doesn't happen and the light on my dash goes out
June 18, 2013
Followup from the Pelican Staff: This forum thread talks about syncing the top.

June 17, 2013
Followup from the Pelican Staff: You are going to have to manually open the top and inspect the parts. If there is a clicking noise, a motor may be skipping or binding.- Nick at Pelican Parts
Comments: what are the steps to sync convertible top on a 1999 Porsche carrera ?
June 14, 2013
Followup from the Pelican Staff: Synchronizing the top on your model is performed using a Porsche scan tool. I suggest taking the vehicle to a Porsche work shop. - Nick at Pelican Parts
Comments: I have a 97 Boxster convertable and when I put the top down then the windows won't go up, not always but this morning I opened and shut the top three times and windows would not work. The windows only go down and not up. Super low mileage like 50K and the car is in great shape...
May 16, 2013
Followup from the Pelican Staff: There may be an issue with a switch in the top. I would check operation of the top and windows using a Porsche scan tool. This way you can monitor the inputs and oputputs and see what is missing or blocking window operation. - Nick at Pelican Parts
Comments: I have a 2001 Boxster S. The left cable broke between the top motor and the left top transmission. I took off both transmissions and ran them backwards and forwards. They work fine. I have new cables installed on both sides. Everything seems to be working great, but the top motor will run to open the top, but will not run at all when the "up" top button is pushed. I do not hear anything in the double relay either when the "up" is pushed, but I do hear the relay when the "down" button is pushed and when the motor is plugged in, it works down, not up. Here are a couple of things I noticed: 1 my top motor does not have a micro switch on top of the motor and it only has two wires coming out of the motor the one on this website has multiple wires coming out of the top motor AND it has a switch on it to signal when the clamshell is down Did some not have that switch? 2 I have removed the double relay and smacked it on the bench to see if that would revive it, it did not.
Am I maybe missing some other micro switch that is not working and needs to be engaged for the top to go up? The parking brake sensor must be working as the motor works going down. Is the double relay, a "double" so that it relays one direction when it is pushed "down" top and the other half relays in the other direction when it is pushed "up" top. I think it must be the double relay? HELP?????? Thoughts???
May 12, 2013
Followup from the Pelican Staff: It's possible the top of a switch is not synced correctly from the cables breaking. Have you tried aligning or syncing the top? - Nick at Pelican Parts

May 4, 2013
Followup from the Pelican Staff: The relay is built into the power top module. You cannot directly test it. You can test the inputs and outputs. connector 1 has the input for the switch, pins 6 , 7. However the best way to diagnose is using a scan tool. - Nick at Pelican Parts
Comments: Hi, I have just purchased a 2003 Boxster S 986 and the roof opens perfectly but when closing at around the half way point I get a loud snapping noise which seems to be coming from the passenger side.
After this noise the roof continues to close.
How do I fix this problem? Thanks.
April 20, 2013
Followup from the Pelican Staff: If you are getting a noise something is either out of alignment or broken. I would inaspect the convertible top components to see where the noise is generating from. - Nick at Pelican Parts
Comments: follow up per comment May 6, 2012. I have found that rubber bushing per Fig 1-H had fallen on left side and able to put it back. However, on the right side the allen cap screw where hex socket is rounded and need new screw. Do you have part number on this screw? Can I buy this from you? Thanks.

November 13, 2012
Followup from the Pelican Staff: If the windows go down as they are supposed to but the top doesn't move, this tells me the front microswitch is working. I would start by checking the top fuses and relay. You could have afaulty fuse or a bad relay. - Nick at Pelican Parts
Comments: Hi Wayne. What a great article and comments. I have a 2005 boxster S 987, and the top won't retract. I unclip the roof and press the utton on the centre console an nothing. Not a sound. The dash indicates its opening. When I lock the car with the remote, the horn sounds a short beep. It looks like a micro switch is not making. Any ideas please? Also how can I retract the top like this to do any repairs? Thanks again
October 2, 2012
Followup from the Pelican Staff: It's possible the front microswitch is not making contact. TO manually open the top:
Unlatch the convertible top at center of the windshield.
Then disconnect the white or red plastic cups at the base of the B-Pillar.
Then disconnect the black rod where they connect to the top V-levers.
Disconnecting the colored plastic cups allows the convertible top to be operated manually.
Disconnecting the black rod allows the clamshell to be operated manually.- Nick at Pelican Parts

Followup from the Pelican Staff: Looks like you have to replace the anchor for the screws. The threaded hole looks damaged from you photo. You could try an epoxy, then drill and retap it, might be worth a shot.- Nick at Pelican Parts
Comments: Hi - I have a '07 boxster 2.7 and recently I have noticed that the underside of the carpets behind the seats luckily on the UK drivers side! are wet after washing or heavy rain. All of the roof drains on the car are clear and pass water quicky. the carpet on the door panels is dry and it appears the leak is coming from behind. Any ideas what may be causing this? thanks in advance
August 29, 2012
Followup from the Pelican Staff: If the drains are clear and appear to be working, the drain pan at the rear could be cracked or the leak could be at the base of the convertible top mounting bracket. - Nick at Pelican Parts
Comments: Hi I am looking for a little help. I am a mobile detailer and detailed a boxster yesterday. I put the convertible top a little down so I could clean underneath the trunk part that come up to hide the top. When doing so, I can now not operate the top properly. That trunk piece does go up and down but the actual top with not go back and fold into that area. Anyone have any ideas as to what I did? Thanks, Scott
August 25, 2012
Followup from the Pelican Staff: Might be coincidence that it failed when you put it down. In the chance that you did do it, you may have hit or damaged an eelctrical component when cleaning. It's hard to say not knowing exactly where you cleaned or what you used to clean with. - Nick at Pelican Parts
Comments: 07 Boxter; Had broken push rods motor kept running so I pulled fuse. Seemed to me module under driver seat had monster corrosion inside. I replaced it, had it programmed at dealer and now I have nothing. Dealer said they could communicate with module and e brake switch was ok,but wanted $$ for more diag. Mobile tech guy said I had no codes,the 2007's don't have an e brake microswitch, and radio should shut off when I release conv top lever. I checked lever microswitch and it is ok. Any ideas?
August 22, 2012
Followup from the Pelican Staff: One of the top relays could be faulty. Likely the top open, there may have been a short caued by the corrosion. - Nick at Pelican Parts
Comments: On a 2002 Boxster, only the left side driver side gets stuck 1/2 way through opening the roof. What parts would you recommend replacing?
August 12, 2012
Followup from the Pelican Staff: This could be a bad drive cable or a faulty pushrod. Inspect the pusrods and see if they are installed. Then check the condition of the cable at the electric motor. - Nick at Pelican Parts
Comments: Also too. With the 98 boxster
It's been hot here the last couple of weeks. Running the car with the ac. The thermostat really starts to rise close to the 120. Is it in need of a simple coolant flush or radiator flush. I know it's hard guess without looking at the car. It just seem every time I take it in. The dealership takes me for more$. Thanks for all your help. This site is great
July 18, 2012
Followup from the Pelican Staff: Are the radiator cooling fans running at high speed? A cooling system flush is a good starting point. You want to confirm cooling fan and thermostat operation too. - Nick at Pelican Parts
Comments: Hi. I have a 98 boxster. The lights on the dash are starting to get dim. And the clock function doesnt even show up anymore. Is there a way of replacing the bulbs behind the dash or do I have to replace the whole control system? If so what do I call it and how much should it cost?
July 18, 2012
Followup from the Pelican Staff: You can service the bulbs in the instrument cluster. Remove the instrument cluster from instrument panel, separate the two halves and replace the bulbs you desire. - Nick at Pelican Parts
Comments: hello, My roof started to act up tonight... only the passenger side is moving and I do hear the motor working. Do these motors ever go on one side or is the motor a dual function and as long as one side is working then the motor must be ok? If so I will start looking at the cable to the transmission on the side of the body...
June 10, 2012
Followup from the Pelican Staff: I would check if a cable is faulty. Anything is possible, but usually if the motor fails both sides break. If only one side is broken, could be the cable. - Nick at Pelican Parts
Comments: I have a 1997 Boxter and my top will not go up. I have followed instruction on how to manually pull up but after poping out push rods I stll can not pull up the main cover that holds convertible top. I need help in pictures showing step by step showing how to do it.
June 2, 2012
Followup from the Pelican Staff: Please look in your owners manual as it explains emergency top operation. I suspect you have not released the drive lever from the drive transmissions on each side.
Comments: I have a 2000 boxster and convertible top motor works but only one side goes up and down. Could you recommend an affordable repair shop near Huntington Beach, Ca? I really appreciate you sharing your knowledge, a couple of shops tried to get me to buy a new motor and rip me off.
May 12, 2012
Followup from the Pelican Staff: I would personally take it to Callas Rennsport over here in Torrance. They know these cars inside and out. On the other hand, if you read the article, it's pretty easy to fix this I think. - Wayne at Pelican Parts
Comments: I have 1998 boxster and hearing a big tudd sound right before the top latches to top windshield mechanism. Just got this fixed about a month ago replaced all the rods and rubber bushings and got fixed. However, during a stop light, I decided to close the top and all of a sudden heard this tudd sound again when closing. When I get home to check mechanism found nothing obvious and tried again but can not duplicate the noise. Any ideas?

Followup from the Pelican Staff: Sounds like it's getting stuck on something. I'm guessing that your rear clamshell is not properly aligned and is sticking on the rear decklid. You might want to have an assistant open and close the lid while you carefully watch the rear decklid to see if it is hanging up. - Wayne at Pelican Parts
Comments: I enjoyed reading your repair article on boxers. Are there any similar repair articles available for the 1987 911/993 convertable top? Please let me know of any information advise or leads you have on that subject. Thanks.

Followup from the Pelican Staff: Not currently. If we get the chance to repair one, we will be sure to create a tech article for it. - Nick at Pelican Parts
Comments: I have a 2002 Boxster and my top has been working fine. no indication of motor or switch proble. When I release the roof latch the windows come down but when I press the opon button on the console, nothing happen. There is no sound as if switch is not working.
Will appreciate any advice you may have. Thanks!

Followup from the Pelican Staff: Check the top fuses and relay. If they are OK, there may be a microswitch that is out of adjustment not allowing the top to open. Does the top open light come on as soon as you press the button?
have someone put a litle pressure on the clamshell, if it opens when you do this, the microswitch for the clamsheel needs to be adjusted.

Comments: Do you have photos for replacing a top my window is cracked and need to replace, any suggestions?

Followup from the Pelican Staff: No sorry we don't. If we get the chance to perform the repair, we will be sure to document it.- Nick at Pelican Parts
Comments: I own a 2005 Boxster S. One of the 4 plastic strips that form the sides of the convertible roof is deteriorating and cracking. Are these plastic strips easily replaceable and do they have individual part numbers? It is the strip that runs along the top of the right door window.
January 9, 2012
Followup from the Pelican Staff: They can be replaced. If I remember correctly, they are held in by six T20 Torx screws. - Nick at Pelican Parts
Comments: Today my 2005 top stopped working, while opened fully. The switch clearly works because the screen displays that the convertible top is closing when I wiggle it, but NOTHING happens physically. There is no motor noise, nothing. I can't close the top. I pulled the fuse e3 and replaced it with the spare 30 amp fuse, nothing changed, still doesn't work. Help?
December 25, 2011
Followup from the Pelican Staff: The first thing I would check would be the motor in the back. Remove the motor and/or wire up 12 volts to it to see if it's operational. Then, just start backtracking from there if the motor works. You can also check to see if there is 12V getting to the motor when the switch is pressed. - Wayne at Pelican Parts
Comments: Ref. Figure 3 above. I need to replace the drivers side push rod. I am not able to compare the length of the old one because it broke off and was severely bent at some point.
How would I go about making sure the new rod is the correct length before installing?
November 26, 2011
Followup from the Pelican Staff: You want to line up the roof, and then line up the mechanism attached to the roof transmission. The adjustment is there to make up for variances in the roof - I would match it to the opposite side to start. - Wayne at Pelican Parts
For this project #71 I could not find the part B in your part place to order. Can you tell me what part # so I can do the order if you don't have it in stock can you give me the part # so I can look somewhere else? Also, do you have the convertible top push rod cap sell separately?
November 14, 2011
Followup from the Pelican Staff: It's called a ball pin, and the part number is 986-561-689-00. You can order it by simply typing the part number into our search engine. - Wayne at Pelican Parts
Comments: Thank you - i just brought a porsche boxster and the electric roof was not working. Im not a mechanic or anything but using your instructions was able to identify 3 faults and get it going again without ordering parts and aligned it too. Many Many Thanks - You have saved me a small fortune.

Followup from the Pelican Staff: No sweat, glad to have helped out! - Wayne at Pelican Parts
Comments: Love the forum! Wonder if anyone can comment on a 2003 Boxster S where the very rear portion of the soft top has come unglued ? a bit and want to reattach. Anyone have a procedure, any guide, recommendation on an adhesive to use?
thanks in advance!!
Comments: My 2000 Boxster top has a problem-will not open. I have
checked fuse-okay. Replaced relay with new-still nothing.
The emergency brake light on dash appears. I have held the
micro switches on top release handle in while depressing dash button-nothing. Only thing at this point I have not
tried is replacing dash switch-I cannot see a way to get to
the back side of dash panel. Everything was working fine-just quit.
Your expertise and help would be greatly appreciated.
Absolutely nothing happens when the dash switch is held in
the on position
November 7, 2011
Followup from the Pelican Staff: Unfortunately, there's no error codes or anything like that for this system (not that I'm aware of). There is another switch that indicates that the clamshell is closed, located in the back by the motor (just above it). That may have failed, although I'm not sure it would show up in this problem. I would check that switch, the dash switch, and also the motor itself to see if it's failed. - Wayne at Pelican Parts
Comments: HI Wayne,
My 2000 Boxster Top is an issue.
pressing the Open button causes a groaning sound in the motor which stops after 3 seconds, and the Top doesnt even move an inch.
How can i resolve this, and more importantly How expensive are the parts.
October 31, 2011
Followup from the Pelican Staff: Take a look at the article here - it covers all of the steps required to troubleshoot this problem. I personally would start with the motor and check the cable. Remove the cable from the two transmissions and see if it spins freely. Then, disconnect the transmission from the top mechanism and see if it also works smoothly. Also, check the whole operation of the top for smoothness by moving it by hand. - Wayne at Pelican Parts
Comments: Does the 944 cabriolet follow the same process as the boxster?
October 24, 2011
Followup from the Pelican Staff: Sorry, I haven't worked on a 944/968 cabriolet. I would guess though that they are not similar, since the Boxster top is very small. - Wayne at Pelican Parts
Comments: How do you reconnect the rear compartment lid push rods once they've been disconnected? The top is in the down position following the emergency top up procedure. The Top has been put back down and the top push rods have been connected but the compartment lid push rods do not reach.
October 11, 2011
Followup from the Pelican Staff: If I read your question correctly, I would recommend that you put the roof up into the 1/2 up position, and then try to reconnect the rods (after lifting the clamshell up about 1/2 way too). - Wayne at Pelican Parts
Comments: hi my boxster s 2000 soft top stop go down and up ibout the top motor and fit it its start move like somthing hold it and it fal faster and stop again bout it start wired with strang sound not like normal bye
October 10, 2011
Followup from the Pelican Staff: Sounds like something in the mechanism is holding up the works, and/or your motor or cable is getting worn out. I would simply go through the steps in the article to see if you can find any worn out components. You just need to start looking at each component carefully. - Wayne at Pelican Parts
Comments: I just need two new push rods.
October 4, 2011
Followup from the Pelican Staff: Thanks for the follow up. We appreciate it. - Nick at Pelican Parts
Comments: The top latch was not fully released when I tried to lower the roof and it sounds like something snapped. The motor lifts the rear lid but does not move the roof at all. Any advice?
nevermind. I just need two new push rods.
October 4, 2011
Followup from the Pelican Staff: Actually, I hate to be the bearer of bad news. If you put enough force on the rods to snap them, then chances are the boomerang-shaped pieces are also bent, and your two transmissions may be damaged as well. This is *exactly* what happened to the white care featured in this tech article. In the end, we had to replace both rods, both boomerangs, both transmissions, the cable, and then we had to bend some sheet metal back into place. Not good. - Wayne at Pelican Parts
Comments: Excellent article. I just got the same issue with my 2002 Boxster, the dealer is asking $1700 to fix it, but thanks to this article I figured out it only needs a pushrod ... thanks again !
September 29, 2011
Followup from the Pelican Staff: Thanks for the feedback. Glad we could help. - Nick at Pelican Parts
Comments: This is a great forum. My 2001 Boxster S top suddenly stopped working. It is in the up / closed position. When I release the top windshield lever, the windows lower an inch like normal, but when I press the dash mounted switch, nothing happens. I think this may be a switch but I don't know how to diagnose this.
Please offer a suggestion. Thanks,
September 25, 2011
Followup from the Pelican Staff: There are a few switches that could be causing this issue. There's one in the back by the motor. There's one in the top of the windshield, and then there's one on the e-brake. I would probably check out all three of these first before moving onto the next step. - Wayne at Pelican Parts
Comments: Can you help. I have repaired the roof after a broken cable BUT now on closing the roof the tranmission, which is the later type with the switch, over rotates and this has now broken another cable. What do I adjust to stop this happening?
August 19, 2011
Followup from the Pelican Staff: If the cable is breaking, then it most likely means that one side is out of adjustment with the other side. If you check the article, you will find the procedure for aligning the roof together using a power drill or the roof motor itself. You can also make sure that the switch is properly operating, otherwise it may not realize that the roof is actually closed. Now that I think of it, that is probably your issue. - Wayne at Pelican Parts
Comments: I removed the broken convertible top cable on the right side and replaced it; howeve, after I installed the new cable and put all back together when I attached the drill to adjust the tansmission nothing turns. When a trnsmisson fails does it cause the cable to break.
August 17, 2011
Followup from the Pelican Staff: I have a feeling that your cable is not seated all the way in either the motor or the transmission. Either that, or the "square hole" that the cable end mates to is rounded out or damaged. Check where both ends of the cable enter into the transmission and the motor and see if the "square hole" is intact and not rounded out. If it is, you'll have to replace that piece with parts from a used motor or transmission or replace the whole motor or transmission (expensive!). - Wayne at Pelican Parts
Comments: The roof cover on my 2000 boxster has a small triangular trim piece that is missing on the passenger side. I have looked through several parts manuals but can't seem to find a part number. Anybody know what the number is?
August 9, 2011
Followup from the Pelican Staff: This is tough to figure out without a photo. I'm going to copy this question to our forums, and send you a link. If you can update the forums with a photo, then we can figure out the part number for you. - Wayne at Pelican Parts
Comments: Just bought a great '97 Boxster with only 16,000 mi on it! Two weeks later, convertable top won't go up and down. My question: If this is a common problem with the original transmission and it has been replace with a "more reliable new one", why won't Porsche at least pay for 1/2 the repairs or supply the parts? This is going to cost me an unexpected 2-3,000.00, by the time I pay for the parts and labor.
August 6, 2011
Followup from the Pelican Staff: Yup, if this had broken within the first two years, then Porsche would have most certainly upgraded and replaced the broken parts. But 14 years later, they are hard-pressed to say that the original owner got good life out of the car. I would buy the parts and do-it-yourself to save one the labor - the procedure is not too difficult. - Wayne at Pelican Parts
Comments: The central roof latch unit attached to the center windshield of my 98 Box just came apart. Other than that the power top works great. What do I do?
July 14, 2011
Followup from the Pelican Staff: I'm not sure what you can do other than replace the unit there. There should be a microswitch in there that tells the car that the roof is properly closed. Without having this switch set properly, you probably won't be able to roll up your windows. - Wayne at Pelican Parts
Comments: Do you know approximately how many labour hours to change the 2 convertible top push rods with the roof alignment after the replacement?
Mine is a 2005 987 Boxster.
July 7, 2011
Followup from the Pelican Staff: I'm not sure, it's a bit of a loaded question. Typically, you don't need to replace these unless something disastrous has happened to the roof. If that is the case, then often there are other components that are damaged, and simply replacing the rods won't necessarily fix the problem. However, to answer your question, it would probably take me about two hours, assuming that is all that is needed to be done. - Wayne at Pelican Parts
Comments: On my Dad's 2001 S Boxster some times the switch to the Top stalls after one hour he is able to close it. It is a bad switch that need to be replaced.
June 24, 2011
Followup from the Pelican Staff: There are at least four switches - the one on the dash, the one in the e-brake handle, the one on the front of the windshield, and one in the back by the motor. It may be any one of these that are causing problems, I would take a look at the windscreen and motor switches first, and then the e-brake one, if you think the problem is switch-related. - Wayne at Pelican Parts
Comments: I have a 2002 porsche boxster and i am considering removing my top to have the back plastic replaced. Is this something that is manageable or should it be taken to a professional. My primary concern is with the double sided tape,sealant, etc. Thanks Matt
May 12, 2011
Followup from the Pelican Staff: It's not really a beginner project - I wouldn't do it if you haven't done many other projects previously. It takes some patience and some skill to get the old roof off and the new one on properly. - Wayne at Pelican Parts
Comments: Wayne I have a 1997 boxster with a top that has seen better days I have a leak passenger rear where the top meets the body of car not sure what seals I require,the top has no power can I disconnect the fuse and operate manually,can I cut out plastic window and replace it with more plastic from the hardware store is there an appoxi type glue I can apply to the rip in my top???? any advise would be greatly welcomed thank you
March 25, 2011
Followup from the Pelican Staff: Yikes, lots of questions here. I'm going to copy this to the forums so that we can discuss it further there. In general, there aren't really many seals on the top itself that are replaceable (like the older cars). If your top has no power, then you have some issues there. You might want to consider bolting a hard top onto the car and driving it that way, as it may be easier and cheaper in the long run. - Wayne at Pelican Parts
Comments: Wayne, what about replacing the plastic gear in the transmission? Mine seems to stripped.
Comments: How do I check or reset my convertible to 996 2001 it will not go down the light just flashes but nothing happens
February 12, 2011
Followup from the Pelican Staff: The roof mechanism for the 996 is controlled by a central computer. In order to figure out what is wrong, you need to hook it up to the Durametric code reader software (or the factory PST-2 tool), and read out the codes for the roof repair. The computer should then tell you what is wrong, and point you on your way to fixing it. The Boxster roof is basically a manual system that doesn't have a complex computer controlling it (just a small control module plugged into the area above the fuse box). - Wayne at Pelican Parts
Comments: Will this work on a 2006 996?
February 11, 2011
Followup from the Pelican Staff: Sorry, no. The 996 convertible uses an entirely different system than the Boxster. The 996 is hydraulic and the Boxster is cable-driven. - Wayne at Pelican Parts
Comments: If my top is down on a 2001 boxster and wont go up and i need to drive home in the rane what can i do to get it up to get it home so i can fix it at home
November 1, 2010
Followup from the Pelican Staff: If you look at this article, you can see where the transmission links to the roof mechanism. Disconnect the balls from the transmission using a letter opener or something like that (they are red in the photo above). Then you should be able to move the top up and down.
Ooops, I just saw that your top is down. You will have to get to these from behind the seats - a much more difficult task, but still possible. - Wayne at Pelican Parts
Comments: Has anyone converted the top to manual operation with long term success? The transmissions are very pricey and I wouldn't mind opening and closing by hand.
October 27, 2010
Followup from the Pelican Staff: Not that I am aware of. You can easily disconnect the transmission and lower the roof by hand, but you also need to disconnect or remove the clamshell too. Without the clamshell cover connected, I'm quite sure it will bounce around and make a lot of noise. - Wayne at Pelican Parts
Comments: Tried the 3M Super Weatherstrip on my problem with the convertible liner on my 2004 Boxster, didn't work. It still pulls out of the track under the latch for the top?
Comments: The convertible liner on my 2004 Boxster keeps pulling away from the frame right under the locking mechanism for the top. Any suggestions on how to get it reattached?
August 29, 2010
Followup from the Pelican Staff: If I'm right in thinking about what you're talking about, then there may have been a factory update for this. On aftermarket tops, there are two "helper straps" that assist in preventing this from happening. In your case, I would try some 3M SuperWeather strip adhesive, but I'm not 100% sure what the issue is, so that may or may not help. - Wayne at Pelican Parts
Comments: I finally got it. You are absolutely right. It is the switch near the motor that is not functioning thats why the lever keeps going around until it gets stock. Thanks for your help
August 5, 2010
Followup from the Pelican Staff: Great! I like it when my guesses turn out to be correct! :) - Wayne at Pelican Parts
Comments: Hi wayne, thanks again. There is something i discovered and maybe i could share it everyone. To align the right and left assemblies, one just needs to disengage one cable, left or right, then use the switch at the dashboard to open an close the top to align. No need for a drill.
Back to my problem, I think it is more of the leverboomerang shapetogether with the push rods getting stock somewhere then the motor stops and it is usually in the closed positionlid. I had to disengaged the pushrodslid to get the motor going again. All I wanted to do is manually open the canvas topcoz those plastic tips of the canvas top push rods brakes easily which i can but I would like the LID to closed mechanically to keep tight and aligned.
August 4, 2010
Followup from the Pelican Staff: Right, I actually mention that method in Figure 7.
On our project car here, we started with the replacement of the plastic ball ends, then the rods, then the triangle piece, then the cable, and finally the transmissions. With all that done, the back cover (clamshell) still did not close 100% perfectly because the actual brackets in the car that attach to the sheetmetal also got slightly bent. So, in order to get everything working again, it may be an expensive proposition. - Wayne at Pelican Parts
Comments: I was able to opened it got the push rods working and the motore working but... now the problem is the motor or switch does not recognize whether the lid is fully opened or closed and the motor just keeps going until it popped all the push rods from their proper places... need your expertise again.
August 1, 2010
Followup from the Pelican Staff: There are two switches, one located in the top of the front windshield, and one located in the mount for the roof motor. I would suspect the switch near the motor is broken. Trouble is, you have to buy the whole mount to get this switch. I would test it with a multi-tester and see if it's broken. You might be able to find a replacement switch at an electronics store. - Wayne at Pelican Parts
Comments: thanks just what i did and it worked...
August 1, 2010
Followup from the Pelican Staff: Thanks for the feedback. Glad we could help. - Nick at Pelican Parts
Comments: Good article but how do you open the rear lid when it is shut closed and will not open by pressing the switch? I can hear the relays click but nothing happens. Is there a manual over ride? I actualy disengaged the two push rods because the plastic tips broke and after doing that I pressed the switch and the rear lid closed and will not open again.The roof is in the closed position becauase i was able to manually pull it up after disengaging the push rods. Need help on this and thank you.
July 27, 2010
Followup from the Pelican Staff: Although I haven't had to do this myself, I think you need to reach in through the passenger compartment and disconnect the pulls for the bottom of the roof and the long plastic piece connected to the roof. Then pull up the back part of the roof. That should give you just a bit of access to remove the engine cover carpet, and then you should be able to reach the motor at the rear, or the clips on the side of the mechanism. Huge pain in the butt. - Wayne at Pelican Parts
Comments: Sure would be useful to have an article about completely removing the top and replacing it with another one as I'm attempting now.
