     If you are not the original owner of your BMW, chances are there are quite a few things amiss with your car, and you are left wondering how they got broken. There probably isn�t a place on the car with more gadgets and devices that break than the door. Not only do you have window glass and potentially leaky seals, but you have door handles, mirror switches, window regulators, door stays, and door panels�all of which are very susceptible to breakage or damage. Even if you only work on your car from time to time, there is a very good chance you will need to dive into the door to fix something that has broken. This project specifically targets the replacement of the door lock assembly, but because there are so many moving parts on the door, I�ll discuss just about everything else as well.

     The first step in working on your car door is removing the door panel. (An important note: If you�re looking to remove your outside mirror, you do not need to remove the door panel; see Project 76.) Photos 1 and 2 detail the process of door panel removal. The toughest part is pulling the panel out from the door�it is attached with 11 plastic clips that can be difficult to snap out of their frames. Also, the door panel often separates as you pull it away from the frame, leaving the plastic door pockets attached. Never fear, though, these are easily glued back on at reassembly time with some 3M Super Weatherstrip glue.

     With the door panel removed, you should see a foam covering glued onto the back side of the door. A black, sticky goo attaches this to the door, which can be removed and reused again if material is still pliable. Be careful not to tear the foam covering when you remove it, though.

     With the panel removed, you will have access to a number of items inside the door. The door stay can simply be unbolted from the door frame and removed. The plastic door handle can easily be swapped out. The window regulator can be removed or repaired (see Project 70). Any door seals or channel guides that need renewing are accessible to you as well. If any door-mounted speakers are broken, don�t forget to replace them while you have the chance. The E36 speakers have a thin outer lip on their housing that often cracks as people bang on the door panel with their feet and knees. Unfortunately, this small lip is an integrated part of the speaker, and you must replace the entire speaker with a new one if you want to fix the broken lip.

     One common failure point of the E36 BMWs is the small switch located inside the power lock assembly. These switches get a lot of use, and when they wear out, they can cause all sorts of problems. Switches that are stuck open tell the car the door is ajar all the time. The dashboard chime may ring continuously, or the gauge cluster may experience some erratic behavior. If the switch is stuck closed, then coupe and convertible owners may have a heck of a time opening and closing their doors because the window won�t roll down that 1/4-inch or so to allow you to pull it away from the car. The replacement of the lock assembly is detailed in the sequence in Photo 5.

     On my 1993 E36, I had a really tough time chasing down a fault with the alarm system and door locks. I thought for sure it was related to the door switches, but in the end, the problem was related to faulty wiring in the trunk. (See Photo 2 of Project 82 for more details on this failure.)

     Closing up the door panel is straightforward. I always like to use new plastic door panel clips because not only are the new ones cheap, the old ones get brittle and may break in the very near future, causing an annoying rattle. Don�t forget to install the foam covering. It�s very common to accidentally leave this on your workbench, only to discover it later on when you�re putting your tools away!

Figure 1

Shown here is the sequence for removing the door panel. A: Slide the outer door handle trim piece toward the front of the car to remove it. B: On this convertible, there�s an additional hidden screw on the passenger-side door handle underneath a small plastic plug. The location and quantity of screws varied slightly over the years. C: Below the handle, two small plastic plugs cover two screws that secure the handle of the door panel to the door frame. D: Eleven of these small plastic clips secure the outer edges of the door panel to the door frame. Carefully pry each of these out of their mating holes to remove the door panel from the door.

Figure 2

Shown here is the back side of the left (driver side) door panel from an E36 convertible. There are 11 plastic clips that attach the panel to the door. You need to remove each of these clips from the door prior to removing the door panel. It will feel like you�re breaking the door panel, but you will need to apply significant force to pull off each of the plastic clips. Use a stiff plastic spatula to wedge the door panel out without scratching the paint on the door. The blue arrows show the back sides of the two door speakers, and the red arrow shows the side mirror switch.

Figure 3

With the door panel removed, you should see the foam covering (top). This material has a plastic back to keep moisture out of the door and a foam front to help reduce noise in the interior. Carefully remove the foam barrier by peeling it back. It�s attached to the door with a gooey, black adhesive. Be careful not to tear the piece as you remove it. The bottom photo shows the door with the foam barrier removed. The purple arrows point to the four rivets that need to be drilled out if you are removing the window regulator. The blue arrow shows the Allen bolt that holds the end of the window regulator to the door. In the inset photo, you can see the back sides of the two door speakers. These speakers need to be disconnected prior to removing the door panel. Reach around the top of the door panel and disconnect the wire harnesses by pulling on them carefully.

Figure 4

The mirror switch simply pops out of the door panel (left). If you need to replace this switch, pry it up out of the door and unplug it. If you�re removing the door panel, then remove this switch. The plastic door handle is a part that can wear out and break (center). With the door panel removed, replacement is a snap. Simply unbolt the door handle, detach it from the actuator rod, and install the new one in its place. While you have access, you might want to replace your door stay, if it�s worn out (right). Simply unbolt it and remove the pin from the body.

Figure 5

This photo sequence shows the procedure for replacing the lock actuator and switch assembly. A: Start by disconnecting the wire harness that attaches to the lock actuator. B: Remove the Torx bolts that hold the entire latch assembly to the door. Don�t forget the bolt that is on the side of the door. C: Loosen and/or disconnect the actuator rod (green arrow) from the door lock assembly. D: Maneuver the assembly out of the door with your hand. E: Pull the entire assembly out of the door so you can access the black plastic actuator on the top of the latch assembly. F: Remove the actuator from the top of the latch assembly, and replace it with your new one.

325IS

Comments: On March 7, 2013 Margaret asked about P/N 51418122408 the metal door panel clip used to replace the �plastic strip� or �top rail� that holds the door panel to the door. The "top rail" is apparently notorious for breaking into pieces � mine did. Nick from Pelican correctly remembered that this parts inserted into the clamps P/N 51211977747 mounted on the door itself, but did not explain how the metal door panel clips were actually fastened to the door panel.

I recently purchased this part and Javier from Pelican sent this link http://www.pelicanparts.com/BMW/techarticles/101-Projects-67-Doors/101-Projects-67-Doors.htm , but this shows only the plastic button panel clips in the door panel and does not show installation of the �top rail� or the metal door panel clips P/N 51418122408 on the door. On my 325IS, 6 of these metal door panel clips are supposed to replace that "top rail" that was glued to the panel and, like Margret, I can't find/figure out how the metal door panel clips are fastened to the panel either. The plastic OEM "top rail" is not sold and was replaced by these clips. Does anyone know how this is done or have a picture?

Gary	Comments: I have a black 1997 E36 M3 coupe. While driving with my windows closed, there would be times when my dome lights turn on like the door was opened, & when this happens & I turn right, the window would go up & down as if someone was pressing on the door striker microswitch repeatedly. During this whole time, I cannot use my powerlock button to lock all doors. Usually this problem resoves by itself but if it persists when I park the car, I would not be able to lock the doors remotely & would have to use my key on the doorlock & turn it clockwise.
April 30, 2013
	Followup from the Pelican Staff: Sounds like your door latch is not holding tight. Push on the outside of the door, you should be able to duplicate the problem. If so,inspect the door latch and microswitch, replace what is faulty. - Nick at Pelican Parts

Craig	Comments: My bmw e36 325i has double locked on three doors and i am unable to get in as the drivers door lock is not in use/damaged. Is there any way of over riding the system?
April 30, 2013
	Followup from the Pelican Staff: This is a tough one. When the doors are double locked, or deadbolted, you cannot unlock them from the inside, only from the driver door lock or with a request from the remote key. If the driver door lock is damaged, the only other option is using the unlock button of your remote key. - Nick at Pelican Parts

Dave	Comments: I need to know how to remove and replace the driver's door lock & actuator assembly on a '96 750il. I have the door panel off, any plugs unplugged, and most of the linkage. The bolts are out too and the assembly is loose, but appears to be hanging up on the keylock assy. Any help would be appreciated. Thanks!
April 22, 2013
	Followup from the Pelican Staff: You'll haver to remove the door lock to remove the latch. There is a rod that goes into the latch, if not removed it will not allow latch to release. - Nick at Pelican Parts

trinidad	Comments: the display is saying door open when all doors are closed...will that kill the battery? what step should i take, there are 4 doors?lol
April 8, 2013
	Followup from the Pelican Staff: This could discharge your battery, especially if the interior lights are on. You may have a door switch that is not functioning. Depending on what 3-Series you have, the switch could be in a few different places. - Nick at Pelican Parts

rich p	Comments: just purchased a 1995 318i conv.. the manual indicates that there is button on the console that opens & locks the doors. however that's not the case, what am i missing, where would it be located? the panels on both doors are loose, right one very bad. what are the steps involved in removing each panel & put new clips in? aboth doors
March 24, 2013
	Followup from the Pelican Staff: The door lock switch is mounted next to the hazard light switch on the center console. To remove the door panels you have to remove the door panel fasteners, then lever door panel clips to release door panel. Once detached from door, disconnect any wires and remove from vehicle. - Nick at Pelican Parts

wp kelpfroth	Comments: The black plastic pieces on my door panel were cracked and not attached to the panel anymore, so I glued them back in place and used gorilla tape to hold them and reinforce the pieces. it's working pretty well.
March 21, 2013
	Followup from the Pelican Staff: Thanks for the tip. - Nick at Pelican Parts

Margaret	Comments: I bought part 51418122408 to replace the plastic strip on the top of the door panel that holds the door on 1996 BMW 328ic. I can see how these fit onto the metal clips on the door itself, but I can't see how they attach to the door card. Can you explain how to attach them to the door card?
March 7, 2013
	Followup from the Pelican Staff: I am going by memory, but if I remember correctly, part# 51418122408 is used to reattached the clamp 51211977747 to the door panel. The clamp attached to door. - Nick at Pelican Parts

Jumanji	Comments: Hi, someone tried to break into my 318 e36, they put a screwdriver in the lock, now the surround trim is broken and there is a hole in the lock, but the key still works in the door, can I get a lock cover or do I need to replace the whole lock, is it a big job and can it be done by myself?? What options do I have?
January 16, 2013
	Followup from the Pelican Staff: The doro handle cover is availabel separately. The lock cylinder is available as a unit. Give our parts specialists a call, they will help you find the right part: 1-888-280-7799- Nick at Pelican Parts

Shady1989	Comments: HI i have a BMW 1993 325i im having a problem with the radiator and door locks. the radiator has access pressure and sprays of from under the cap and the door locks do as they please i unlock then it locks right away and vise verse very hard to get in the car please help.
December 19, 2012
	Followup from the Pelican Staff: Excess pressure in the cooling system could point to a faulty head gasket. The door lock problem may be related to a faulty lock cylinder switch. Once you release it, it reads LOCK and relocks the door. - Nick at Pelican Parts

Comments: 1987 BMW 325i coupe. The ignition key will not unlock the doors or trunk, it will fit and turn the tumbler but NOT unlock. The central locking mechanism works great and i found this out when the car wash locked the door and asked me to move the car forward. Both doors and the trunk were locked tight! Vice versa when I managed to pull up on the lock knob and all locks unlocked. What causes the key to discontinue working in the lock mechanism?

jeremiah.minor	Comments: Hello, I have a 1994 BMW 325i coupe RHD. After returning from my vacation my driver window regulator motor clicks very loudly after the door closes. I opened up the panel and it seems that it is the geared portion of the raising and lowering assembly inside and not the regulator motor itself. Is there a way to reset the motor or the linkage?

Comments: This needs a genius maybe, im completely puzzed...

Problem: Even though the drivers door of my e46 coupe is unlocked, it wont open neither from the outside nor from the inside.

Extra info:
1. Surprisingly, suddenly at times it starts opening normally! but then after a short while back to the same problem unlocked but not opening neither from the inside or the outside.

2. I unlock my car manually using the key since the remote battery seems to be dead but it unlocks fine and I've been doing it long before this problem.

3. The central lock only opens the passenger door and not the drivers door. However, this is recent and the original problem existed before this issue.

Any help what the problem could be? And what parts I need to change? ...something electrical or mechanical, or both :o ?

Thanks

joe-in-md.	Comments: I recently purchased a door handle assembly from pelican parts, I had a BMW shop install it, when I went to pick up the car everything worked fine, door handles unlocked, and window fit perfect. A couple days later the new door handle lock stop working, when inserting the key it turns freely as if there is no actuator to unlock the door. When I go to the passenger side, all the doors unlock. Any suggestions???

The auto feature will work, but the glass will stop at any point without being fully open or closed. I suspect a sensor is bad. Is there a way to disable the sensor?

But right now need access to battery as it is dead.

Comments: In response to "sam has a stuck door", I had the same exact problem this weekend and was able to open the door not by working at the pins on the mechanism, but by pulling the hollowed rectangular-shaped lever on the top of the mechanism closer to the outside part of the door. The lever may be hidden from sight if you look at the actuator while it's still attached in the door but if you search for images of the e36 locking mechanism, you could see what I mean- and where it is on the top of the mechanism.

sam has a stuck door	Comments: My 1996 328i driver front door is stuck shut and neither the inner or outer handle will open it; locked or unlocked, key in or out, or in any position. I'm sure it's the latching mechanism double locked?, but I can't remove the mounting bolts while the door is stuck closed. Is there a way to manually unlatch it to open the door so I can replace it? :/

Comments: i recently replaced the water pump on my 1993 e36 now my alarm flashes and when i try to lock the doors they just keep unlocking, the only way to lock my car is to unplug the battery and do it manually, not only that but the door ajar light doesnt come on even if the door is open, the interior lights flash randomly even if all doors are closed, and my SRS light flashes for a few minutes and then stays on... i find it weird that all this happened cuz i had to change my water pump along with the bands, are they related in some way? thanks for ur help

KevinL	Comments: Hi there, ever since I bought my bmw 318 1994 there has been a locking problem that i cant figure out. The central lock works from the driver's door. When I try to lock it from there however the doors would become unlocked and this will take several tries about 7-8 until the locks decide to stay locked. Any ideas what is going on?
June 21, 2011

Dazedandconfused	Comments: After more research I'm even more confused. My door won't latch. If I press the door hard enough the window rolls up, I can turn the key and lock the door, I can pull the interior lock up and down and see that it actuates, so my assumption is that my door lock actuator is actually good. I just can't get the latch to grab the strike plate. What do I do?

Steve	Comments: I have an 88 E30 M3 with a broken door brake. I have removed the brake from the door itself but the arm is still connected to the frame. Does the unit you sell include the brake and the arm also or would I reattach the new brake to the existing arm?

Comments: Hello, I have a 1994 bmw 740i, I am familiar with all systems except the door and window mechanisms. When I got to work this morning I could not roll up my front drivers side window back up it made it halfway before it came to an abrupt stop, then proceeding to get out of my vehicle I noticed that I could not!! The handle would not work on the inside, so I tried pulling the door lock up, and it was jammed! I have no idea what it could be, ideas? All 3 of my other doors, locks and windows all work. I have been trying to look online with really no luck so far. Thank you so much for any help! As always thanks for the amazing service you have to me over the years :

Comments: My door latch has broken cast metal on the frame itself and the door is getting hard to open. I believe it's part # 51218199923. It shows parts comes with key & latch. Can I take the key cylinder out and use my own so I can keep using the same key? When I order this new latch will I have to get it coded? Not clear about the coding thing and if I can use my own key cylinder. What to do?

Comments: Had a question about a door locking problem i've had. I've got a '98 328i that recently had more or less total power locking failure. One day everything was fine, the next nothing automated works. The locks still manually work with the key just fine, but the locks won't pop up for anything elseincluding the central locking button and i'm afraid that the security system is nonfunctional as a result. I've checked all the fuses can't find anything visibly amiss. Any ideas of where I should look next to troubleshoot?

unstuck in London	Comments: Hello, thank you again for your help. The latch mechanism itself was completely broken. It has no ability to actuate the catch spring to release from the sticker bolt. Got lucky after playing with it for 3 days. Door open, new latch/lock on order. If your door is completely stuck get your hand inside door panel and manipulate the door release handle towards the car exterior until it pops. It may take a long time. If the car door latch has a few weird moments and is getting sketchy replace soon.

stuck in London	Comments: Hi, my door is shut, will not open. I have removed door panel and actuator switch. I can move the lock mechanism, move the interior door arm, outside is loose but connected. Still cannot get door to open. Whats next
April 8, 2011
	Followup from the Pelican Staff: The outside door handle has a small plastic piece that connects to the main door lock assembly. Often this is broken. You need to find this piece (see door lock article above) and then pull on it, and you should be able to open the door. The replacement piece is about $5 if I recall correctly. - Wayne at Pelican Parts

duke	Comments: how can I install my after market alarm 4x extreme to the locking and unlocking wiring that I can't find under the drivers dash. Also the side flashers wires I can't find. Do they run through a module away from the drivers kick panel. Do you know the exact colors and location. I would love to see a video. Should I check the passenger side for the wires.

March 4, 2011
	Followup from the Pelican Staff: You might have to reprogram the remote. I have an article on this here: http://www.pelicanparts.com/bmw/techarticles/101-Projects-92-Alarm-Install/101-Projects-92-Alarm-Install.htm - Wayne at Pelican Parts

bobby	Comments: i have a '93 325is. last week, while moving the car, i heard a steady clicking noise for a while, seemed to be in front of me under hood. finally it stopped. after that, no power locks or windows worked for a day or two. then, i had intermittent window operation, and passenger door, trunk, nothing yet driver side. oh, when they work, i get a double click-if i turn to open, they click open, then click shut, and i need to turn it open once more and it stays. same when i close. very puzzling. could it be a bad control module, or one or more of its ic chip freakouts, a bad ground, perhaps an actuator or microswitchalthough, i suspect not likely for more than one to go bad at once, but, who knows? i thought if an electrical or electronic component goes bad, it's kaput, so this is puzzling. is there a fuse that could be in play, or anything around the fuse box, where i thought the noise came from? is there any simple way to test, or should i begin with the most obvious central possibilities and work my way back?
March 1, 2011
	Followup from the Pelican Staff: Electrical problems are a bear to try to solve over the Internet. However, the clicking noise you're talking about may be related to a relay failing? Perhaps, but I'm not convinced, as relays are very quiet usually, and don't make loud clacking noises. It could be a control module - I think you need to start tracing back the circuit to see what connects all of these components together, in an attempt to try to find a common fault. - Wayne at Pelican Parts

Geno	Comments: I own a E30 1988 325I 4 door sedan. Central locking system question. I am able to unlock from both side doors and from trunk lock cylinder. I able to lock from trunk and passenger front door only. Not able to lock from drivers door cylinder. My actuators in door and trunk move up and down. I think the micro switch on the door cylinder is bad. It has 2 wires going to it. I tested my theory and jumped the 2 wires and the actuators all worked. How do I remove this micro switch part # 61 31 1 375 137 . Also there is a lever arm #61 31 1 368 987 also to remove. Tough spot from within door. Do i need to remove window to access?
February 23, 2011
	Followup from the Pelican Staff: You're way ahead of everyone else in terms of identifying the problem. In order to get to this switch, I believe that you need to remove the door lock mechanism from the door itself and disassemble it on the bench. To do this, you need to remove the door panel - you typically don't have to remove the window, just roll it up to access the mechanism. - Wayne at Pelican Parts

Richard	Comments: Hi there I have a 1997 e36 318is 4 doors BMW euro version. On the driver�s side door the key will go into the lock cylinder but it won�t turn right or left in order to open or close the door. To be able to go into the car driver side I have to open the passenger side lock with the key or the trunk lock, and then the driver side lock will open. When I am inside the car, driver seat, everything works fine from the inside; I can open the door, as well as, lock it or unlock it. Please I need your help on what is damage??? So that I can order the proper part from you. Advanced thank you for the broad help : Richard
February 12, 2011
	Followup from the Pelican Staff: There's a little plastic clip inside the door that connects the door handle to the reset of the mechanism. It's shown in the pictures in the article. I think that's the problem, but you really need to open up the door and take a look inside to make sure before you order the parts. - Wayne at Pelican Parts

duke	Comments: The drivers door on my 1997 528i is locked. the electric locks seems to open but when you pull the door latch both from the outside and inside the door will not open. How can I get the door to open?
February 7, 2011
	Followup from the Pelican Staff: This is a bad situation to be in. I had this happen once, and it wasn't pretty. The door lock mechanism is broken. I would keep trying to mess with it to see if you can get the door open - don't give up just yet. If nothing works (try just about everything), then you need to remove the door panel to get to the door lock mechanism. I think you might need to remove the driver's seat for this, which means also removing the passenger seat (in order to pull it out of the car. Then, the removal of the door panel is not easy with the door closed - there are lots of trim pieces that are in the way, and on your 5-Series, I'm not even sure if it's possible with the door closed - you may have to cut through the door panel. I have my 1998 at work right now, otherwise I would take a closer look. Good luck! - Wayne at Pelican Parts

Lew	Comments: Hey the door sensors on my 1996 m3 don't sense the door closed. Previous owner put loose zip ties arount that works but they shift then the door is not seen as being closed, How do it fix for real?
January 27, 2011
	Followup from the Pelican Staff: This is definitely a problem with the microswitches that are contained within the door lock mechanism. The only good solution is to take the door apart and replace the mechanism itself. You can try tearing apart the mechanism to get to the switches and try to repair them, but I don't recommend that. - Wayne at Pelican Parts

england steve	Comments: i can only open and lock my bmw 328i 1996 convertable fromthe boot the key wont even turn in both front doors please could someone help
January 24, 2011
	Followup from the Pelican Staff: If you look at the article here, you will see that there is a plastic piece that connects the door lock mechanism to the actual key and door lock. These plastic pieces have a tendency to break. Replacing them is relatively straightforward, but you need to remove the door panel and get in there to reach them. - Wayne at Pelican Parts

John	Comments: To replace the door locking mechanism are there special tools required to remove panels/locking parts? If so, are they sold by pelican parts? can you provide a list?
January 21, 2011
	Followup from the Pelican Staff: Nope, no special tools required - just follow the instructions in the article. The only odd tool you might need is a 12-point star tool to remove some of the side door hardware. We sell these in our catalog as well. - Wayne at Pelican Parts

PJD	Comments: I have a 98 328i and just recently when I went to open the driver's side door from the inside interior something broke from the handle inside the door. The handle now swings freely without tension and is useless. I have to roll down the window and use the outside handle to open the door. What broke off inside, a cable? Can't seem to find any info on it.

Mike1025	Comments: bmwmarko, are you certain that someone jammed a screwdriver into the lock cylinder? If not, I would check that your key is not starting to get worn out. Try a newer spare key to see if problen persists. Most locksmiths can take the door apart and replace the lock with matching key.

January 6, 2011
	Followup from the Pelican Staff: Take a look at my article on the doors and replacing the lock mechanism. You need to remove the mechanism and see what you can salvage. There's a little plastic piece in there that connects the handle to the door lock - that may be what is broken and damaged. If so, it's a very easy fix. - Wayne at Pelican Parts

Dazedandconfused	Comments: Your comment to BMW12345 stated that it was the mechanism that was bad and that you sold it. I have the same problem. Do you have a specific name for it so I can buy it. Is it the actuator, assembly, or something else. Thanks for your help.
January 2, 2011
	Followup from the Pelican Staff: It's the door lock actuator and switch assembly mechanism - the box with the latches and switches in it that attaches to the inside of the door. See the article on replacing it, it's shown in Figure 5 in the article. - Wayne at Pelican Parts

dschwalm

Comments: I ordered a rear door actuator from you for my 1997 M3. I got the old one off finally, but I cannot for the life of me get the new one on. I can get everything lined up but can't get enough leverage to snap it on. There is not enough space to maneuver around with my fingers. The opening are quite small. I could barely get the actuator in so I can't see how I could get the locking assembly out. Can you give me any tips?

September 5, 2010
	Followup from the Pelican Staff: See Figure 5/C - the rod that is attached to the handle needs to be disconnected, either at the latch, or from the door handle itself. I can't recall which one is easier to remove, but there shouldn't be a major problem with removing it. - Wayne at Pelican Parts

Simon	Comments: I have euro e36 M3 1997 coupe. The door handle on the passenger side becomes sometimes loose so I can't open the door neither from outside or inside. The door lock is unlocked the pin is up but the inside and outside hadle won't open the door. When I press the door strongly from the outside under the door handle toward bodywork it makes "click" and the door becomes functional again so I can open the door from outside or inside. Could you tell me which part of the lock is faulty?
September 1, 2010
	Followup from the Pelican Staff: I'm not sure - you'll have to remove the door panel and take a look up in there. There are a bunch of plastic connector pieces that often break - I suspect it's one of them. - Wayne at Pelican Parts

Nea	Comments: I have an '03 Z4 that i need to get the door panel off of. My door wouldn't open from the inside or out. I did discover a trick that may help others... put the key in the door turn and hold to the unlock position and then reach in and pull the inside door handle. The door opens! Need to figure out how to fix it though. Can anyone tell me how? Thanks
August 20, 2010
	Followup from the Pelican Staff: Z3 panels are similar to the E36. As for figuring out the lock mechanism, it's probably a broken plastic connector piece inside the door. Take off the panel and take a look at the mechanism - the damaged piece is usually obvious. - Wayne at Pelican Parts

Bearclaw	Comments: After talking to several mechanics, there is another item in the central locking circuit to check. Especially if you live in a northern climate. There is a connector under the driver's seat where the whole system is inter-connected. The salt and moisture tend to leach along the carpet and rot the connector. Turns to a green powder like a trailer connector. My one mechanic just cut the wires and used a waterproof heat shrink. Voila! Central locking now works like new.
August 19, 2010
	Followup from the Pelican Staff: That's good advice, thanks for sharing. The computer that is under the seat is the alarm system computer, and it can indeed get really screwed up if you let it rain on your car with the top down. - Wayne at Pelican Parts

collardog	Comments: I have a 1994 e36 325i vert and the drivers door window stopped dropping down. the alarm works fine as does the door locks eith with the key or with the keyless remote. the passenger window works fine. I pulled off the panel I have your 101 projects book and the wires are fine and clipped into place. Is there a switch or sensor that just controls the window drop mode or is this part of the actuator in the door. some sites suggest there is a sensor in the latch on the body of the car. tks Les
July 13, 2010
	Followup from the Pelican Staff: If you mean the window dropping down when you open the door, then yes, there are microswitches in the door lock mechanism that control this. The replacement is documented in this tech article, and should fix the problem. - Wayne at Pelican Parts

Bill	Comments: i have a 1994 bmw 525I the drivers front door will not open I can't get the door panel off. how can I get it open ?
July 4, 2010
	Followup from the Pelican Staff: Hmm, I don't think I've been asked this one before. I'm not sure, but I would guess that you would start by removing the seat, and then taking off all the screws that secure the panel. I don't think there's anything on the door that keeps the panel locked into place when the door is closed. - Wayne at Pelican Parts

Bob Goding	Comments: 'New'owner of a 95 e36 318 is coupe with window electrical gremlins as described above.[the car is RHD.Japan assembled] The L/h [pax door]window works as I expect it should,but the drivers window has a mind of its own. I know I will have to open it up and fix it, but can you tell me why the window does that drop when the door opens and closes when the door is shut, The pax window doesnt do that. I know that its for the convertible,-but why on this coupe and why only on the r/h door? Can I bypass the lock switch to prevent this?--Thanks, Bob
May 17, 2010
	Followup from the Pelican Staff: The window is supposed to drop down when you open the door. It's the passenger side window that is broken. It has to do with the fact that there is no pillar between the roof and the door, and the car is designed like a convertible. The window lowers down to release it from the roof seal, and then slides back up to seal it into place. - Wayne at Pelican Parts

Is there anything I can spray in the lock cyl graphite, WD40, etc. to maybe unstick it? What are my options?

Comments: If you are getting water inside the car you need to replace the sound insulation and "black sticky goo". I paid $24 for each of the rear doors and the "goo" is 3M Windo Weld Ribbon. BMW calls is butyl tape but it's the same stuff, trust me. Use anything else and you may as well use silly putty. And don't forget those neoprene seals on the door panel clips. I did and had water pouring in through that same hole.

November 10, 2009
	Followup from the Pelican Staff: There are a lot of small plastic pieces in the door that break after many years. You really can't tell what's wrong in there until you tear it apart and take a look. Most of the time, it's obvious once you get the door apart. - Wayne at Pelican Parts

Tom	Comments: where is this write up for the e30 door panel, the e30 and e36 essentially look the same, but Im just wondering, besides the speaker configuration if there are other differences. I have an e30 and im starting to get problems with opening the passenger door from the inside. the outside works fine but this inside is where the handle is not opening the door mechanism fully, without pushing on the door to open or almost breaking the inner door handle to open the door. I like this site just found it today actually, will probably use this to purchase my parts from now on.
September 18, 2009
	Followup from the Pelican Staff: Yup, the door panel removal process is pretty similar for all cars. You just need to pop the panel off and take a look at what's inside. Usually, it will be obvious what the problem is (broken pieces of plastic, etc.). - Wayne at Pelican Parts
