Porsche Air Conditioning
Frequently Asked Questions

 

     I hope that at least one of the reasons you are here is to learn something about the air conditioning that's in your Porsche or is going to be in your Porsche. Personally I don't see how anyone would want to drive around in a car, especially a Porsche that can't keep it's occupants cool. Now, if the car is used strictly for racing, well then I can understand, but if their other car is a Toyota and it can freeze their socks off well then we had better get to work and right away ! The air in a Porsche can work as well as any other car on the road with out exception ! All the components that are in a Mustang are in a Porsche 914 or 911 or 968, its just that the parts are located sometimes in a different area because of how the car is laid out. 
  • The compressor is still driven by the engine, so it is mounted firmly to the case and connected to the Crankshaft by a belt.

  • The Evaporator is inside the passenger compartment so that air can be picked up by the fan and sent across the cooling coils and back out through the vents.

  • The condenser that is normally placed in front of the radiator in a 'real' car must be placed in the air stream or where there will be a steady high volume of cold air since this is where the freon sheds the heat that it has picked up inside the Evaporator.

  • The Receiver/Drier like those most 'real' cars use would be under the hood and have a 'sight' glass on the top so that the technician can see if the system needs additional freon is mounted somewhere on the body in the liquid line that runs from the Condenser to the Evaporator.

  • The biggest difference between a Porsche and the rest of the cars on the road is the amount of rubber hose that is needed to connect all these pieces together. In the past this was the biggest problem because all this hose had been made to purposely 'bleed' freon much like your skin bleeds air. The hose was actually pricked through the outer layer each inch or so to prevent the hose from blossoming from the pressure inside. What this meant was that Porsches were subject to the lose of much more Freon than the other cars and thus had to be topped up more often. That's the only downside.

So you see, there is nothing so Mysterious about the air conditioner in your Porsche !

But, if the technician that you take your car to for repair says that he doesn't know anything about the air in a Porsche, get back into your car, hook up your seat belt, drive off and seek out another tech.

Comments and Suggestions:
JJComments: Ctd. from below. Forgot to mention the car. It's a 1990 944 S2.
April 13, 2012
JJComments: I have a broken AC switch button on the dash. The AC still works but only if I hold my finger on the switch. Otherwise it won't stay engaged pressed-in. I have attempted to remove the switch but can't figure out how to get it out of the dash unit. I also can't believe this little button costs $100+ if you can find one.

89-944NAComments: What refrigerant was used in the 1994 968, R12 or R134a?
April 9, 2012
RufusComments: I have a 1983 944. My heat works great blowing through the vents but my AC does not blow through the vents. I keep feeling it on the passenger side in the floor board. Please advise what I need to look for or do.
March 26, 2012
vinComments: I am having question about the a/c of porsche cayenne.when do we need to replaced the dryer cartridge and what is the symptom or reason to replaced it.
March 15, 2012
PeterComments: I have a 1994 ROW 993 C2. The aircon works perfectly and blows cold air when the temperature dial is turned all the way counterclockwise to the coldest setting. But when I turn it even just 1 or 2 clicks clockwise so it's no longer at the coldest setting, the vents all blow fully hot air. Any ideas what might be wrong?
March 10, 2012
spyglassComments: 1987 944 Porsche Aircon. Fuse #29 7.5 amp keeps blowing. Tried 10 amp but that failed after 2 hours. Any ideas what to check or what may be at fault would be appreciated.
February 12, 2012
RickComments: I would like to wire in an electric fan mounted to the deck lid of my 1986 -911 to draw more air across a new condenser mounted in the Whale tail. I would like to wire the fan to turn on when ever the AC compressor is activated. Can you please recommend how best to wire it in?
January 8, 2012
dcromComments: I have a 1990 911 Carrera 2. One of the switches in the Climate Control Unit is broken. Are the switches available individually or can you only replace the entire unit for about $1200? I haven't been able to find it in the PP parts lists.

wittComments: I would like to REMOVE the a/c from my 1988 Porsche Carrera cabriolet. It's not cooling all that well and in my part of the world it is not realy needed. So far I have identified most of the hard parts, is it worth the trouble to remove that snakepit of hoses ? Are any of the parts good to anybody ? Would love to hear from someone who has done that kind of work before.
CHEERS !
WITT !

RobComments: What is needed to be done in order to change the a/c switch on the dash of a 1986 944 non turbo? Does the dashboard need to be removed?
September 8, 2011
DougComments: Today the a/c in my 1999 996 cab is warm and there is a clicking sound coming from under the dash on the passenger side. Can you tell me what I am looking for there that is AC related as I research how to access the area?
September 2, 2011
LuisComments: Need to know if 912e a/c parts are available compressor mounts blowers ect
August 11, 2011
MrMoleComments: I have a 1985 911 cabriolet. I took the belt off the compressor 10+ years ago because the a/c never cooled very well and i got tired of replacing Freon. Will there be a problem if I put a belt on and recharge the system at this late date?
August 8, 2011
57lincolnmanComments: I have a '75 914 and trying to get the A/C working. Replaced compressor with a Sandis unit, new drier, reused existing expansion valve, all new plumbing and fittings. The evaporator and coil has been inspected. It is not blowing cold air. The car won't idle with a/c on. When it stalls the car develops a vapor lock and won't start. Thoughts?
August 6, 2011
golfr71Comments: I have an 89 928s4, the ac runs out in the front of the car within a week. The back will continue to blow cold air though. Any ideas or help?
Thanks in advance for your help! Mike
August 6, 2011
EZComments: I want to convert my 87 944 to R134 but do not know what to do beyond adding the conversion fitting,is there more to it than that? do I need to purge the compressor of the R12 first? If I do how do i do that? Thanks
July 22, 2011
yellowperilComments: I just had to A/C recharged in my '86 911 and it again blows fairly good cold air but I notice the compressor is noisier than previous years, ka-thunking. Can I run it like that or should I rush out and purchase a new compressor. They are reasonably priced 350-450 $$. Also, might be my imagination but the motor seems to heat up much faster than before and the air temp here never gets much above 23-25 C low 80's The compressor doesn't seem to drag no big RPM drop, but it is a bit noisy. Thanks
July 14, 2011
Dan RachmelowitzComments: 928 AC control unit was blown out by a sloppy mechanic at Rayco in Eatontown NJ. Is there anyway to fix the controller without spending 1,300 plus another 600 in labor?
July 9, 2011
marshallComments: looking for the a/c condensor drain hose for my 86 928
July 7, 2011
RoyalComments: I have a 1983 911SC with the old A/C system. Do you think it's possible that I can test and possibly leave the existing hoses and simply replace the accessible parts? As long as there's no major leaks, the only apparent downside is the need to recharge every year or so with cheap R134A... and if it becomes a problem, I go ahead and replace with the $400 hose set and major labor later on? Is here any sense in this?

I do know that the newer hoses are smaller diameter for some reason - pehaps to increase the velocity of refrigerant through the system?
June 22, 2011
LuisPorscheComments: I have an 87 944S, and would like to get some A/C going for the hot summer, but the system only takes R12 and that is not available in stores... rumors have it that some places may sell it but will charge an arm and a leg due to the environmental controls. Anyhow, I have seen the R134a conversion kit which adds some sort of valve. Is this something I could use and do myself? You mentioned earlier that 'extensive' changes are required, but I wonder if I can get more detail. Also, I don't know how long it has been not working, so could other things be wrong with it clutch?. The fan blower works, heat works great. Thanks!
June 17, 2011
HarveyComments: I have a 1988 Porsche Targa. In the 14 years Ive owned it, I the system's been recharged 8 times. And of those times it's been every year for the last 3. Despite dye in the system, they can find no leaks. Dealer mechanic says the hoses have been extra microscopicly porous and that's where I'm losing the 134 freon. Thousands to replace hoses, he says. Best to keep refilling it every year. Isn't there a better way to run this railroad?
June 17, 2011
chris ghiatisComments: I have a 1997 993. One of the two rubber hoses next to the compressor has a stain. It is like a dry leak, but It is not wet. I have to recharge the ac every year. Do I have a leak? If I re-charge the ac with 134a with stop leak will it help? Thank You Chris
June 7, 2011
shovelheadComments: Where do you access the evaporator on a 1976 911? I tried to pull a vacuum on the system and thought that maybe my pump wasn't working. When I turned the AC on and started filling it with Redtek 12a It started escaling out from under the driver's side front fender.
June 2, 2011
swedenComments: 1991 911 carrera 4.
My ac is not working, so I'm going to drain the system with a vacuum pump. And when this is complete I will fill it again. So my question is how high the pressure should be? 80 lbs? Thanks Wayne u r great.
May 25, 2011
sjphdComments: My 964 A/C fan is only runnimg slow. It runs for a few seconds, then stops and then does the same cycle? The air is not cold.

Any ideas?
May 3, 2011
RobertComments:
I have recently replaced my a/c and now note the fan/blower is not working correctly. It only works in the 'full' setting and it can be switched off. The other 2 settings do not work, i.e. no air comes out.

I understand this could be a faulty resistor bridge?
April 22, 2011
Tkid007Comments: Thanks for the response. Found out my A/C clutch bearing was froze, waiting on reman compressor. Have another question, my cruse control won't engage. It will excellerate with the lever but it will not hold/set speed. any suggestions?
April 21, 2011
Tkid007Comments: I have an 85 944s and the A/C quit working. I charged the system two weeks ago and it was doing fine, now the compressor won't engage. Can not find a fuse, only a relay. how can I trouble shoot the relay and ac switch?
April 18, 2011
 Followup from the Pelican Staff: You can try sending 12V to the A/C clutch to see if it engages. If there is low or high pressure in the system, the clutch will not engage (it has override switches). These switches can also sometimes fail. I'm in the midst of troubleshooting this same problem on my 959 right now. - Wayne at Pelican Parts
2porscheguyComments: Thank you for your response to my previous query regarding the Carrera chain tensioner upgrade...I will call you when I'm ready to order the kit. Another question regarding my 1980 911SC Targa...living in Calgary, Alberta I am considering removing the AC unit as I rarely have the need for AC. In addition to removing the compressor, what other parts should be removed? Is there any harm to the engine in doing so? Would I expect any increase in performance?.....many thanks again! Your site truly is a great resource for Porsche enthusiasts alike!
March 8, 2011
 Followup from the Pelican Staff: If you remove the A/C system, then you can take out everything that is associated with it - the compressor, the lines, the front condenser, the rear condenser, the evap unit near the dash. All of this adds considerable weight, so removing it would indeed increase the performance of your 911. - Wayne at Pelican Parts
JimboComments: I have a 1986 944T which has just had the aircon modified at a cost of $850 to accept a new type of gas however its performence is woeful when the ambient temperature gets above 26 deg c, I am told that is the best I can expect. At 32 deg no cooled air is available. Is there a fault in the modification that the aircon mechanic has overlooked.
February 10, 2011
 Followup from the Pelican Staff: Well, there are correct and incorrect ways of modifying the system. Some mechanics simply fill the system up with R134a and then change a valve or two to try to make it work. In reality, you really need to change a lot of the system components to R134a specifications. The new refrigerant is indeed not as effective as the older R12 stuff, so you will indeed see a decrease in cooling performance. - Wayne at Pelican Parts
lundyComments: My 1990 C4 A/c is not working . The blower fan works. When I press the A/c button, the button light comes on, but I cannot hear the system "engage" like it used to. Similarly the engine revs do not drop when I press the button, so I assume the compressor is not going.
I have checked the fuse to the a/c compressor and it it intact.
I have had a flat battery since the last start up, when I thought the A/c worked, and recharged with a trickle charger , if this is relevant. Any suggestions?
February 10, 2011
 Followup from the Pelican Staff: There is a system pressure switch that will stop the compressor from activating if the pressure in the system is too low. I'm troubleshooting A/C problems on my 959 right now, and I think that the issue on my car may be this pressure switch. I would check this out and make sure that continuity is constant across the switch. Otherwise, the compressor is not going to kick on. - Wayne at Pelican Parts  
bnissimComments: hi friends
i need the technical details to install a/c system in 1976 911 if same one can help pls
respond to bnissim@013.net
February 8, 2011
 Followup from the Pelican Staff: I don't have this information handy, but I will move this question over to our 911 Forums to see if anyone there can assist. - Wayne at Pelican Parts
go282Comments: i have 87 911 ,cabin blower motor is not running. is there more then one motor i need
January 24, 2011
 Followup from the Pelican Staff: There should be one blower motor behind the dash that powers the ventilation system. If you have "auto-heat" in your car, then the control unit inbetween the seats may be suspect as well. - Wayne at Pelican Parts
PiafComments: Looking to install a/c on a 1994 993 non ac car,is this possible is there a complete kit?
January 17, 2011
 Followup from the Pelican Staff: No complete kit that I'm aware of. The 993 is an electrically complicated car - I think it would be easier to sell the car and purchase another one that had A/C installed from the factory. - Wayne at Pelican Parts
juggerComments: I have a 2010 997 w/5000m
A few months ago began to have intermittent moldy smell from A/C...now its all the time. Any ideas?
January 17, 2011
 Followup from the Pelican Staff: Try changing the cabin filter in the front. Also check that area for leaves and debris that might have caught water up there. Here's an article on the Boxster's filter, but it's in the same place and is almost identical to replace: http://www.pelicanparts.com/techarticles/Boxster_Tech/03-BASICS-Air_Filter/03-BASICS-Air_Filter.htm - Wayne at Pelican Parts
GavinComments: I have an '86 Carrera running R134, otherwise the AC is all original. Currently low on refrigerant so I haven't had the AC running as yet. If I was to replace one of the condensers at the same time as the hoses for improved performance, would it be the front or the rear? I am assuming the bigger one rear - correct?
Thanks
January 16, 2011
 Followup from the Pelican Staff: Unless you're going to be replacing it with a larger, more efficient one, then there probably won't be too much difference. But if I had to choose, I would probably choose the front one. - Wayne at Pelican Parts
JeffComments: A 1989 911 C-4 I am interested in buying says the AC needs to be charged every 2-3 years and that that is normal. Is it? Seems a little too often to me. Thanks
November 24, 2010
 Followup from the Pelican Staff: For a car that old, that doesn't sound too bad to me. That shows that it has a very, very small leak, but not enough to dramatically affect performance. - Wayne at Pelican Parts
EllisComments: Have a 1984 928S...28k miles....in the middle of replacing the a/c compressor, a/c dryer and expansion valve. Cleaned the entire system before install. The new parts are installed and unable to get the system to take any freon on the low side...acts as if it is blocked? Any help would be appreciated.
November 12, 2010
 Followup from the Pelican Staff: I'm a bit lost on this one as well too. I don't see how it would be blocked, unless there's something seriously wrong with the compressor. - Wayne at Pelican Parts
BobLComments: I have a 1985 944 n/a. AC compressor works and blows cold air but keeps blowing fuses. Additionally, heater seems to make warm air, but does not blow warm air through vents. Any thoughts on what the problem might be?
October 15, 2010
 Followup from the Pelican Staff: The compressor itself is a mechanical device, and isn't electrical - the clutch is electrical, and is probably what is blowing fuses if you are having problems. I would probably take a close look at the clutch and/or check to make sure you have the correct sized fuse in there. - Wayne at Pelican Parts
dawgComments: I have ordered the relay for the smugglers box it is cheap enough that replacement rules the relay out. the fan motors for the ac system seem to be elusive to me. I can hear a fan running in the front of the car and in the engine compartment but i do not hear a fan for the occupants of the car. Where are the ac fans located for the occupants and what is the access pathway to them?
Thanks.
September 7, 2010
 Followup from the Pelican Staff: The blower motor you're looking for is located in the front trunk, sortof under the wipers. You need to remove the cardboard panel that snaps in there (under the carpet) to gain access. - Wayne at Pelican Parts
dawgComments: I have an 89 911 the relay in the smugglers box keep blowing fuses any help? Is this common and the relay just needs to be replaced or do the motors tend to go bad. If so what access for the side motors? Thanks.
September 5, 2010
 Followup from the Pelican Staff: Relays don't typically blow fuses - the loaded motors and other devices typically are what blow the fuses - I would check for a short circuit or blown motor somewhere. - Wayne at Pelican Parts
ChokyComments: A/C on my 1991 928 is working well after being fixed, but the rear A/C is blowing hot air only!
Can anyone tell me what might be the cause?
August 23, 2010
 Followup from the Pelican Staff: I'm not too familiar with these cars, but I would guess that one of the flappers in the duct system is not functioning properly. - Wayne at Pelican Parts 
daveComments: 1985 911 A/C doesn't get cold. Had recharged and tested and guy said all was good. Bentley manual troubleshooting has yielded nothing. Evap motor: fine; blower motor: fine; compressor has voltage and spins but I can't tell if it works or not; way to test compressor? no visible leaks; evaporator under tail looks good, evaporator under moter has slight damage but coils are intact. resistor pack? I don't have access to professionals without driving 3 hours thank you!
August 12, 2010
 Followup from the Pelican Staff: Yes, you can check the system pressure using a standard gauge. Here is an article on the Boxster A/C system, but you can check the 911 system in a very similar manner: http://www.pelicanparts.com/techarticles/Boxster_Tech/97-MISC-AC/97-MISC-AC.htm - Wayne at Pelican Parts
Jeff 928Comments: I have an 86 928S. Getting water in the driver's side footwell quite a lot of water actually. Been trying to diagnose it for weeks! Originally thought it was the cowl cover under the hood which is flimsy and broken and does need to be replaced. I actually first noticed it after a rain storm and a car washing. But the water still happens with no rain, car not having even been wet for weeks. Then I thought it was an AC condensation hose or drain hose leaking. And it does seem to be worse when the AC is on. But I drove the car twice yesterday & today about 15 miles each time with the AC off, and I'm still getting water coming in. The water coming in is very warm. it is not coolant, though. This is making me nuts. Help!
July 23, 2010
 Followup from the Pelican Staff: Odd problem. The water is indeed either coolant, or leftover water from a storm that is trapped somewhere in your car. I think you need to keep hunting, if you're sure it's not coolant. - Wayne at Pelican Parts
billComments: i have a late 89 964..the ac was recently recharged and blows cold...but the water produced in the cooling process falls on my feet in both front floorboards...is there a drain hose that could be disconnected or plugged ? thanks
July 19, 2010
 Followup from the Pelican Staff: Yup, there should be a drain hose that channels the water to the bottom of the car - sounds like it fell out and is missing. - Wayne at Pelican Parts
mjsluvs2wrkComments: I have a 1986 928S. I just had the ac fixed. Upgraded with new compressor and dryer. The rear ac works good but the front won't cool. Any suggestions on what to look for or what the problem might be.
July 14, 2010
 Followup from the Pelican Staff: Sounds like the vents that choose between heat and cool air are stuck open or closed. This is controlled by the AC computer on the dash. You'll have to start looking in that direction to find the problem (either the motors that control the flaps, or the controller itself). - Wayne at Pelican Parts
Boxerboy17Comments: I have a 1995 carerra.The a/c system puts out cold air on the right side,and heated air on the left side.Is this like American cars that break blend doors,or is the actuator the most likely cause.
July 13, 2010
 Followup from the Pelican Staff: Yes, it sounds like there are one or more flappers behind the dash that are stuck and / or broken. Sometimes some foam gets stuck in the flappers or they just need tweaking. You can sometimes free them by tapping on them with a long, flexible pickup stick stuck down the vent. - Wayne at Pelican Parts
BobComments: Please ignore my question below... got it resolved. Was low on r134
July 1, 2010
BobComments: I have a 95 C2 and the AC is barely cool. Belts and all look good. Is this a r134 or r12 car? Thanks!
July 1, 2010
 Followup from the Pelican Staff: 1995 should be R134a - Wayne at Pelican Parts
lachComments: Need to purchase/install AC in 1975 911S. Any references in the Houston Tx area? Thanks
June 20, 2010
MELComments: mY 1988 911 DOES NOT COOL , THE HIGH PRESSURE SIDE IS HOT BUT THE LOW IS NOT COOL. aFTER YEARS OF TOPPING OFF THE SYSTEM CAN TOO MUSH OIL GET IN THE SYSTEM AND BLOCK IT? tHE PRESSURE IS AROUND 80 LBS COULD i NEED AN EXPANSION VALVE?
June 16, 2010
 Followup from the Pelican Staff: It could be one of many different things. If you've been topping off the system for a long time, then perhaps the fluid is contaminated - you may want to get it evacuated and then refilled. Sounds like it may need a trip to an A/C expert. - Wayne at Pelican Parts
jdComments: Since my post I found I need Ester Oil not Pag Oil and also I have to pull a vacuum.I think this is correct.Any help in this matter will be greatly appreciated.
June 2, 2010
jdComments: I have a 1984 944.A/C was working 2 years ago but evidentally leaked down so now I want to convert it.I bought 2 cans 134a and 1 can Pag oil,new reciever/dryer,o-rings,and fittings.Took it to a shop but they wanted to put in r12 and I decided to convert it myself now there is no pressure on the system.Can I just drain it,blow it out,drain the compressor,change reciever/dryer,fittings,o-rings,and then????Should I put in a can of 134a and then Pag oil and top off w/134a ?
Thanks,
jd
June 2, 2010
 Followup from the Pelican Staff: You probably have a large leak somewhere in the system. You need to find the source of that (most of the time you need specialized leak tester equipment) before you refill the system. - Wayne at Pelican Parts
928guyComments: I have an '87 928 S4. It hold fine for 2 or 3 weeks and then tapers off. Is there anywhere know to leak? I hate to keep replacing parts and not solving the problem.
April 26, 2010
 Followup from the Pelican Staff: There's a leak somewhere - the only place to find it is with a leak tester. Basically, you fill the system with a special dye and then use a leak testing machine to go around all the hoses and see where they are leaking from. - Wayne at Pelican Parts
jdoubluComments: im lookin for a shop to find freon leak in 1988 carrera. i live in san jose ca. 95127. any reccomendations?
March 26, 2010
RezzoComments: I have a 89 911 that is perfect except I can't seem to keep refrigerant in the air conditioner lines. When charged it will stay up for about 2 weeks and then gone. This has been going on for 8 years. We have put dye in and used a sniffer. Looked through the glove box and used the sniffer and nothing. Can not figure out where the refrigerant is going. Is there some secret place that you would know for us to look?
March 11, 2010
donnmaddyComments: I have a 88 911 and I have a musty smell comming from my ac vents. I think that my evaperator is pluged so I ran a long zip tie in a drain hose that is on the outside bottom of car at front passanger floor board area. There are two drain hoses with ac hose running betweene them. I do beleve that the smaller of the two is the evaperator drain hose, but not sure. No water came out of hose after inserting zip tie so I am not sure what my problem is. Do you have any idea what it could be. Thanks Don

gtexComments: I have an 87 911 that needs air conditioner and brake work. Do you know of anyone in the Houston area that's excellent?
January 17, 2010
GregComments: I was told by the mechanic that rebuilt my solex carbs. on my 912 that I need a preheat hose for them to work properly. I no longer have the heater boxes but do have the piece around the j pipe at the end by the flywheel.There's also an attachment for a hose on the right side engine compartment toward the back. Would that be a good place to connect my preheat hose? Thanks.

bobbyComments: My 79 911SC AC works but I notice when I feel the switch which controls the fan speed gets very hot after a few minutes of running the AC. Could this be a sign of the switch going bad or there's other reasons for this? BTW, love this site, keep up the good work!

 Followup from the Pelican Staff: I'm not sure, perhaps this could be a bad resistor pack. The switch shouldn't get hot - that means there's more current running through it than should be. - Wayne at Pelican Parts
AgporscheComments: I am having a problem blowing my a/c fuse when compressor engages. I can see that compressor is not locked up when a/c button gets pushed. System is air tight, no leaks. I can feel and see where the electrical leads attach to the compressor are loose. Could this be my problem? If so, how the heck do I tighten it can't gain access to it

 Followup from the Pelican Staff: Yes, it sounds like the leads have come loose and made contact with the housing, which has created a short circuit. This may or may not be fixable, you'll have to probably remove the compressor and take a closer look. - Wayne at Pelican Parts
TimComments: I am restoring a 1967 Porsche 912 and want air conditioning bad. Are any of the aftermarket kits that Roger Eaton talks about still available? Is there any new aftermarket kit available? I am open to any ideas or suggestions. Thanks - Tim.

 Followup from the Pelican Staff: I think that RennAire may offer a kit to install new A/C on these cars. Give our sales dept a call at 1-888-280-7799 and they can check for you. - Wayne at Pelican Parts
MeeshComments: my 1976 porsche 911S has an AC system that runs on R12... what should i do to change this to run in R134?

 Followup from the Pelican Staff: Give one of our sales guys a call at 1-888-280-7799. There's a whole kit that needs to be installed. - Wayne at Pelican Parts

djkikwlongComments: I am having issues with my 88 944 N/A. The csr had been sitting for a few years with the AC working before. I tried to recharge the system, and it took just enough to engage the clutch and no more. I also noticed that the oil was a bit dark in color. To me it seems clogged, also on the reciever/drier it is dry as a bone. Help
August 5, 2009
 Followup from the Pelican Staff: Sounds like you need to draw down the entire system, replace the receiver/drier, add some compressor oil and then refill. - Wayne at Pelican Parts
TovrinComments: I have Broken this piece, 944-653-922-00-M100, and am trying to find information on how to disassemble the control assembly to replace the part, or how do tell if i can, since the title states "Only for Control Assembly With Replaceable Switches".

I am also interested in a wiring diagram for this component.

 Followup from the Pelican Staff: You can replace that switch if you take apart your entire A/C control unit. I would just buy a used on on eBay though - they run less than the cost of the new switch! - Wayne at Pelican Parts
jbsf100Comments: I have a 87 911 and the front ac blower motor is sounding real bad. My question is: is it as simple as taking the old one out and putting the new one in? Do i have to take into account the refrigerant? not sure if this is part of the sealed system or not. Do you have instructions somewhere on how i can do this myself? I checked through the site and couldn't find it, but after all i am a man so finding things is not our forte. thank you
July 26, 2009
 Followup from the Pelican Staff: The blower motors can be replaced fairly easily - they are not part of the sealed refrigerant system. The front blower motor in the front trunk can probably be replaced in about 10 minutes. The ones behind the dash are more complicated. Depending upon the year, you gain access through the front trunk or the dashboard. - Wayne at Pelican Parts
rhipleyComments: 1989 911 carrar 4
changed the oil yesterday...now the compressor will not come on. Worked fine last used 2 days ago. Freon on other??
July 8, 2009
 Followup from the Pelican Staff: Hmm, maybe the wire that connects to the compressor got bumped? I'm not sure of anything specific with an oil change that would cause the A/C system to stop working. - Wayne at Pelican Parts 
StanComments: I am trying to install an A/C in 1973 914. I have picked up most of the pieces, but I am looking for more. I have the condenser needs work the vent/blower that mounts under the dash. Where do I find more and most importantly, where do I find info. on how it is bolted up? Thanks...

 Followup from the Pelican Staff: Yikes, that's probably a 13-page article all by itself! Try Griffiths, they may have some parts. - Wayne at Pelican Parts
VDDComments: I have a 1974 911 2.7L. I live in the Pasadean area and I need someone to work on/replace my non-factory A/C. Do you have any names of really experianced a/C experts. te car is very clean and I'd like the A/C guy to be fastidious.

 Followup from the Pelican Staff: The best guys I know of in the LA area is Callas Rennsport. www.callasrennsport.com They are located in the South Bay (Torrance), but have solved tricky A/C problems for me in the past. - Wayne at Pelican Parts
