Porsche Air Conditioning Frequently Asked Questions

Applicable Models:

 
Porsche 911 (1965-89)
Porsche 912 (1965-69)
Porsche 914 (1970-76)
Porsche 930 Turbo (1976-89)
     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.

Nickoxr Comments: Hi Nick thanks for the reply what is the amount of aircon refrigerant is needed in a 1984 944 and also where is the low side pressure switch located. THANKS
August 25, 2016
  Followup from the Pelican Staff: I don’t have that info.



I would grab a repair manual. It will have the procedure, special tools and refrigerant specs.

Give our parts specialists a call at 1-888-280-7799. - Nick at Pelican Parts
 
benanick Comments: i have a 84 944 aircon it clicks on for 15 seconds and cld air and off for 40 seconds can it be expansion valve problem .
August 24, 2016
  Followup from the Pelican Staff: Sounds more like a pressure switch or low refrigerant charge. - Nick at Pelican Parts  
RyanNaman Comments: I have a 2003 Cayenne , AC works great during cooler temperatures. Under 95 Degrees. Once it gets hotter the AC just does not work and will start to blow hot air. I looked through the asked questions did not see one to address this situation. Thank You!
August 15, 2016
  Followup from the Pelican Staff: Confirm the condenser fan is coming on and the condenser is free of debris. If there is poor air flow, the system will stop cooling. - Nick at Pelican Parts  
Carlton Comments: 1985 Porsche 928, 71,000. Frist time on the road in 2 years, My air condition doesn't turn on, or the 4 speed air switch, the switch moves, just no air, nothing at all. When I stored it all was fine, the fuse, #8 & 17 are ok, I am not sure about relay #5. This is were I should be looking? Thoughts
August 13, 2016
  Followup from the Pelican Staff: I would assume the refrigerant leaked out. Start by checking the system pressure. - Nick at Pelican Parts  
Czar Comments: hello I have a 1984 944 and I'm starting to fix it up and I need to find out how much Freon does it take after I do the retro fit to the car?
July 15, 2016
  Followup from the Pelican Staff: I don't have that info. Look at the tag under the hood for the charge amount. - Nick at Pelican Parts  
Thierry Comments: Cayenne S 2006. hvac recirculation flap actuator? Any idea where I can source this actuator online? Is that the same part on the vw touareg? does it require to remove the dash? Many thanks
June 29, 2016
  Followup from the Pelican Staff: Give The Pelican Parts parts specialists a call at 1-888-280-7799. They can figure out what part or repair kit you need.


Depending on which actuator, the dash may need to come out.

We don't currently have that tech article. If we get a chance to perform the procedure, we will be sure to document it.

I would grab a repair manual. It will have the procedure, special tools and torque specs.

Pkcayenne Comments: Hi I'm looking for A/C Intake Air Temperature Sensor. 2004 Porsche Cayenne turbo I have intermittent Ac usually works best when it's hot outside or when the engine is hot after 40 min
June 26, 2016
  Followup from the Pelican Staff: COuld be a low charge or weak compressor.

- Nick at Pelican Parts
 
Nonell Comments: HI everyone, I have a 996 carrera with one condenser to be replaced, the car has been sitting with the system open to the atmosphere for some weeks, the question is: Should I replace the receiver/dryer??

Thanks in Advance
March 4, 2016
  Followup from the Pelican Staff: Yes.

rsing Comments: i am buying a 991 gt3 rs, and considering an a/c delete due to weight saving and the expression of the car. The radio is already decided to delete. Two questions, how much weight do I save, and would I gain any power by not having the belt run the compressor, also with ac off? Also wondering how much work and how much to gain from just removing the compressor after receiving the car, then being able to put it back before resale. For the record, this car will mainly be tracked when in my possession, and I fancy the image of the old RSes, which came with no equipment and clients that didm´t expect it to serve for daily driving. RS should have a commitment to anyone lucky enough to get one, and that involves leck of comfort. If you go to the forrest you sleep in a tent. Also the idea of it being a fraction faster then "all" other RSes makes it special, although it will probably never be noticed on the clock.
November 4, 2015
  Followup from the Pelican Staff: It really depends on your plans. With the a/c off, you aren't stealing much power from the engine. The weight savings may be around 15 pounds, max. - Nick at Pelican Parts  
Fred Comments: I have a 87 944 Base model that was stored for a few years. Many issues, but most solved. AC worked, but just stopped a few days ago. Took it to my mechanic who could not solve the problem. It is full with R134. When you turn on the AC, the compressor does not come on. If you turn on the defroster, the compressor comes on. I installed another automatic temperture control unit and got the same results. Could the R134 casue any issues?Any suggestions or help? Thanks, Fred
November 1, 2015
  Followup from the Pelican Staff: R134 would not, unless the pressure was too low, due to the wrong charge amount. Might be the pressure switch. - Nick at Pelican Parts  
DARYL Comments: Im having trouble my my ac blowing warm air the past 4 days. Clutch doesn't engage. relays are ok. I turned on the car today and it starts to blow cold air again with the clutch engaging but when i turned it off the ac starts blowing war air again. Please advise. I have a 2008 honda accord.
October 11, 2015
  Followup from the Pelican Staff: The charge may be low. Start by checking system pressures. - Nick at Pelican Parts  
Louie Comments: where is the ac condensation drain located on the 99 boxster? When I run the ac the floor is wet on the passenger side.

Thanks
October 8, 2015
  Followup from the Pelican Staff: It's hard to get to front under the vehicle. Remove the panels in the passenger footwell, then look for the drain tube at the bottom of the heater box. Remove it and clear using stiff wire. - Nick at Pelican Parts  
Casey Comments: SOMEBODY PLEASE HELP-I have a 1986 Porsche 944. AC recently stopped working and I noticed even the heat would not work on the temp control unit. The only thing that worked was the fan. After some research it appeared to be the Temp control unit in the dash....so I bought a new one 600 bones. Put it in today and no dice. Still having the same issue. Also replaced the compressor relay switch. With the heat and AC not working it's got me puzzled. Help!
August 22, 2015
  Followup from the Pelican Staff: Does the compressor relay have power and ground? is it being switched on when a/c is turned ON?

Can you jump the compressor on via the relay and does the a/c cool? - Nick at Pelican Parts
 
FBC Comments: I have a 1988 924s. The a/c works fine when at idle and the air comes out the middle vents. When I accelerate the vacuum actuated flap under the dash loses vacuum and moves the air from the middle vents to the floor vent. The vacuum lines seem to be hooked up properly. Is there a way to test the vacuum reservoir. I am stumped. Everything looks ok.
July 27, 2015
  Followup from the Pelican Staff: Sure, detach the line to the valve, then connect a vacuum gauge in place. What is the reading at idle, then when you drive? - Nick at Pelican Parts  
Akmal Comments: Hi,

i have Porsche cayenne 2004 GCC Specs, i changed compressor, expansion valve and condenser unit including receiver drier, i start filling gas but ac is not working, may i know what will be the cause
July 12, 2015
  Followup from the Pelican Staff: You may need to put the a/s system into a vacuum to get ti accept new refrigerant. - Nick at Pelican Parts  
JH Comments: I'm having trouble with my air conditioner. It blows air with the engine turned off, however, once the engine is running, it no longer blows air. Any suggestions?
July 3, 2015
  Followup from the Pelican Staff: What kind of vehicle? - Nick at Pelican Parts  
GabrielS Comments: My '84 928s a/c started blowing warm air, I suspect it lost it's R12 charge. At this point I'd like to convert over to R134A. I'm not clear where the high and low pressure valves are located so I can apply the appropriate adapters, the engine compartment is packed pretty tight. Does the receiver/dryer and expansion valve have to be changed? Thank you for your input!
June 20, 2015
  Followup from the Pelican Staff: I would replace the dryer and expansion valve. Best to start with some new parts if retrofitting. Especially if there was a leak.


The Air Conditioning Service ports are located on the top of the Air Conditioning Compressor. And additional low pressure port may also be located on the suction line on the passenger side of the engine compartment between the Expansion Valve and the Compressor.

High Side Service Port
Diameter 3/8 in.
Pitch 24 threads per inch
Thread direction right
Low Side Service Port
Diameter 7/16 in.
Pitch 20 threads per inch
Thread direction right - Nick at Pelican Parts
 
Doukas Comments: Hi I have a 2003 996 Carrera, my vents inside the car are blowing smoke or steam and I also have a leak of some type of oil from the passengers side under the glove box.. Does anyone know what that can be??
May 27, 2015
  Followup from the Pelican Staff: Your A/C evaporator could be leaking. - Nick at Pelican Parts  
JonathanEngr Comments: Hi! A while back I asked a question and you answered:

Comments: I have a problem with the a/c on my 2000 911 C2. It works 100% of the time when I start my engine, but after running for a bit the a/c stops blowing cold air. Sometimes this happens in a few minutes, sometimes much longer. Running the fan to full and/or the temp to LO sometimes works, but not always. And when the air is working, it's very, very cold. I would like it to be consistent so I can use the AUTO setting. Any thoughts on this intermittent issue?

Followup from the Pelican Staff: Are the condenser fans running? If not, the system pressure may get too high, turning off the compressor. - Nick at Pelican Parts

Where are the condenser fans located? There is a fan that comes on intermittently on the front right side of the car. Is this a condenser fan? Is there only one? Thanks!
May 22, 2015
  Followup from the Pelican Staff: There should be two fans, one at each corner of the front bumper. - Nick at Pelican Parts  
mchamp Comments: Hi. Cayanne 4.5 non turbo, 2003/4. A/C not working. Changed compressor and re-gassed. Same problem as with original compressor getting power to compressor but will not blow cold.
May 1, 2015
  Followup from the Pelican Staff: What are system pressures with the A/C off and when commanded on? - Nick at Pelican Parts  
Luke Comments: 2004 Carrera 4 Cabriolet - squealing coming from climate control. Stops when fan is turn off or fan speed is increased. Is it possible to lubricate or do I need a new fan motor.

Thanks
April 30, 2015
  Followup from the Pelican Staff: The blower motor is likely faulty. You will have to replace it. Check to see if there is any debris in the heater box first. - Nick at Pelican Parts  
Lake Guy Comments: I just purchased an 84 911 Carrera. I was trying to figure out how to engage it and I've determined that I don't have the a/c switch or fan switch that should be mounted on the top of the console. There is noting on the console at all but I have the compressor, rear condenser, front condenser, various fans, etc. Is it possible that this version of 911 doesn't have switches? The manual states that there should be one for the a/c and one for the fan. I've also checked the fuse block and I see a small inline fuse blown and the A/C relay block is missing. What can you assume this all means?
April 26, 2015
  Followup from the Pelican Staff: I think the switch should be on the control panel. Maybe yours was swapped with one without the a/c option? - Nick at Pelican Parts  
CarreraTex Comments: Dear Pelican Experts. I have a 02 996 Carrera 911 coupe and within the last two months I have noticed that my A/C was blowing less cooler air. Today it is just blowing hot air. My imitiate thought was freon was low so bought a kit at local auto supply store. When I connected the gauge, the meter went striaght to the High warning red zone. What could possibly be wrong? Thanks!
April 23, 2015
  Followup from the Pelican Staff: I would have the system pressure checked. You could have a low charge, the charge kit you bought may not be reading right. - Nick at Pelican Parts  
Nodnarb Comments: I own a 2006 Cayenne GTS w 4 zone AC. No matter what I have the AC controls set at I get hot air coming out of the passenger side dash vent in center. Any idea what the issue is ? A stuck damper? Bad Temp sensor? The fan adjustment os odd also - by increasing fan speed on passanger side in any mode -drivers side velocity increases.
Any Help ? Thanks
April 19, 2015
  Followup from the Pelican Staff: You need to check the faults in the climate control unit. Could be a bad temp sensor, stepper motor, control unit, or even low refrigerant charge. Step one is check faults... - Casey at Pelican Parts  
Butch Comments: I have a 1996 911. The air conditioner was working fine until I moved the thermostat knob up one notch. Then it started blowing hot air out of the vents. Moved thermostat back to the cool position and it still blows hot air. Even if system is completely off it still blows hot air through vents. What steps do I need to take to correct the problem.
April 10, 2015
  Followup from the Pelican Staff: First confirm the A/C compressor is coming on and off. if it is, you may have an issue with the temperature control flap or fresh air flap. - Nick at Pelican Parts  
wallic Comments: How do you turn a/c on, i could not find on/off a/c button anywhere. I have 05 porche boxter
April 4, 2015
  Followup from the Pelican Staff: There is no specific button for A/C. The system turns on depending on your interior temperature setting. Check your owner's manual for more information.- Nick at Pelican Parts  
PK Comments: I have had trouble with keeping my 2002 911 turbo battery's charged. Techs say I don't drive enough. Once a week for 30 miles is what I average. Today I had to jump start the car and while driving it I noticed that the voltage level was at 13.7v vs. the normal 14 volt level. Turning of the A/C immediately brought it up to 14v. A/C works fine otherwise. Should the compressor load cause this? Any ideas?
March 17, 2015
  Followup from the Pelican Staff: You may not be driving the vehicle enough. Charging voltage sounds OK, I would be curios what charging system amperage is when the vehicle is started, at idle and under a load. - Nick at Pelican Parts  
JA Comments: I have a 2004 Boxster S. I've identified a noise in the engine compartment coming from the A/C compressor. two questions:
1 how can I test the A/C clutch to see if that's the problem
2 is it possible it's running out of synthetic oil? where can I check? can it be added without having to take the compressor apart?

February 10, 2015
  Followup from the Pelican Staff: Refrigerant oil is added using an a/c service machine through the low side service port. No way to do it without it.

You can remove the drive belt, then spin the a/c pulley and check for noise or binding.
- Nick at Pelican Parts
 
Qatar CTT Comments: Hi guys, I have a 2008 CTT cayenne... leaking water in footwear, asked a garage to clean the a/c drain. They did this... hardly any water came out. Seemed OK and fixed the issue... few months on it is happening again? I live in the middle east so not a rainy place to cause a quick clog up of drains. Ideas welcome. C
January 13, 2015
  Followup from the Pelican Staff: if the A/C drain fixed it for a while, I would recheck that. Have them inspect the heater box for debris. It may be full and replugging the drain. - Nick at Pelican Parts  
NineELF Comments: My 2006 997 C2 A/C on high fan setting will initially blow at top fan speed then will step down to low speed despite being set on high within minutes. Pulling the windshield washer stalk causes an increase in fan speed. The fan resumes high for several minutes then decreases again. At first I thought this was coincidental but is often reproducible and not drive time dependent. What could be causing the Fan's variability
January 12, 2015
  Followup from the Pelican Staff: Is this a manual system? It could be the temp hits a point then lowers fan speed. Possible issue with the evap sensor. - Nick at Pelican Parts  
Behnam Comments: Nobody hier?.....?.....
December 31, 2014
  Followup from the Pelican Staff: What can I help you find? - Nick at Pelican Parts  
Behnam Comments: I have Cayenne 2004s,blower fan works about 30seconds good,then not,look like that something is in fan and he block fan.and then same story again.
is that something with instalation on my display or just with fan .if i clean blower fan and make it good with white grease spray have i any chance for
Good resultate?
thanks a lot.
best regards
Behnam
December 27, 2014
  Followup from the Pelican Staff: Do not try to lubricate the blower motor.

Check the signal to the blower motor when it fails, if it is still receiving power and ground to turn on, and is not, replace the blower motor. If it isn't, check the final stage unit.- Nick at Pelican Parts
 
Vik Comments: I have Porsche Cayenne 2007. The front air con vents does not flow much air even the fans are full on. The cold air is coming thru side vents as full on, but the one in the middle, seems to be blocked..any reasons why would that be? Regards
December 13, 2014
  Followup from the Pelican Staff: Could be a faulty mode door or vent. Try activating the mode doors using a Porsche scan tool. If one doesn't respond, it may be faulty. - Nick at Pelican Parts  
ozzy Comments: I have a 996 tt 2002 , air con was great , now just blows coolish air , could i have lost the gas , where is the reciever drier located so i can check , thanks
December 11, 2014
  Followup from the Pelican Staff: Could be a leak, there are a lot of lines and connections that can leak. I would start by checking the ac system pressure. The dryer won't be your issue, however it may require replacing if you find a leak. - Nick at Pelican Parts  
robbath Comments: I have a 2006 Boxster S with Manual A/C control unit.

Is it possible to replace the manual unit with the Automatic unit, which was available as a factory option?

What would I require in terms of extra sensors, wiring harness etc...?
December 10, 2014
  Followup from the Pelican Staff: I'm not 100% sure. I imagine it will require the control had and a module or software update. Give our parts specialists a call at 1-888-280-7799 and they can help figure out which part or repair kit you need.
- Nick at Pelican Parts
 
Steve K Comments: I have a 1999 Boxster, the AC blows very cold and after a while a white vapor starts coming out of the vents like a fog. Whats the cause and how do fix the problem?
November 22, 2014
  Followup from the Pelican Staff: White smoke may be refrigerant leaking. Check the a/c system for a leak. - Nick at Pelican Parts  
Manny Comments: I have just purchased my first Porsche, a 1997 993. All is well so far, except for the air con. It was regassed just before I purchased it and was working well for the few times I used it. The other day, after I used it for a couple of hours the previous day, a very nasty smell was coming out of the vents. It was still cooling at that stage BUT the smell was unbearable to me. The smell has continued and now it won't cool at all. Just blows smelly air. Hard to describe the smell. It's sort of a musty smell but also a little gassy and I think it may have irritated my eyes slightly. What could be causing the smell? And is that the likely arson for no cold air?
November 22, 2014
  Followup from the Pelican Staff: The smell could be mold in the evap or a refrigerant leak at the evap. i would check system pressure and have the system leak tested if needed. If there are no leaks, have the evap disinfected. - Nick at Pelican Parts  
Scott Comments: Hi, 996tt ac clutch is engaged all fuses are ok but no air is blowing. Could you please tell me what else to check?
November 18, 2014
  Followup from the Pelican Staff: Check the blower motor and resistor. - Nick at Pelican Parts  
Vinz Comments: Nick, do u have a picture of thr pressure switch? Thanks
October 22, 2014
  Followup from the Pelican Staff: No, sorry I don't. - Nick at Pelican Parts  
Vinz Comments: I beoieve its 200..very high
October 22, 2014
  Followup from the Pelican Staff: 200 with the system off, that is too high. The system is overcharged. - Nick at Pelican Parts  
Vinz Comments: My 97 boxster aircon compressor wont ebngage. Freon is full. Snowflake button wont stay on. Sometimes on first start the compressor engages then 10 secs later it turns off. Is it a relay problem? But relays are good when checked. Fuse is ok. Any advise?
October 21, 2014
  Followup from the Pelican Staff: Likely a pressure switch issue. What is the system pressure when the engine is idling? - Nick at Pelican Parts  
Vinz Comments: No codes were lifted as the a/c worked fine when the technician checked. But when i went home the a/c blower again did not work
September 25, 2014
  Followup from the Pelican Staff: You stated earlier there was a flap error. I would start by addressing that fault code.- Nick at Pelican Parts  
KWal Comments: I have a 1983 Porsche 911 sc. My front ac condenser blower motor is working but is making a lot of noise. It is vibrating as well.
September 23, 2014
  Followup from the Pelican Staff: Check the fan blades for damage. - Nick at Pelican Parts  
Vinz Comments: I have a 96 bosxter. My aircon blower suddenly stopped. My technician erased a flap error. Then it worked fine..after 5 days the blower did not work again. What can be possible problem? Is there a flap motor? Pls help
September 21, 2014
  Followup from the Pelican Staff: COuld be a flap motor issue. What was the fault code? - Nick at Pelican Parts  
mxer54 Comments: i have a 2004 cayenne s and the ac blower will not shut off even with the motor off and key out. i was able to locate the fuse and pulling it shuts it off. any ideas?
September 19, 2014
  Followup from the Pelican Staff: COuld be a faulty blower control unit. - Nick at Pelican Parts  
Javid Comments: In my 2012 Panamera, when I hit a signifigant bump I hear and audible tone and the AC stops working for 20 seconds and then comes back on. Any thoughts?
August 31, 2014
  Followup from the Pelican Staff: Check if the battery is loose or the hold down isn;t secure. - Nick at Pelican Parts  
CSG Comments: Hello, recently got a 2001 Boxster 2.7. AC works fine but gives out a terrible smell. Smell is not musty but more of a chemical smell. Similar to a break rotor overheating. AC never stops working and no noises. Everything seems fine but smell. Any ideas?
August 27, 2014
  Followup from the Pelican Staff: Inspect the blower motor. It may worn, causing the motor to emit the odor. - Nick at Pelican Parts  
Dr Mark Comments: What are normal high and low side AC pressures at 80 degrees for 1989 928 S4?
August 26, 2014
  Followup from the Pelican Staff: If the charge is correct: 80°F Low 30-40 psi High 190-220 psi - Nick at Pelican Parts  
Chaidez1994 Comments: Hi I recently bought my 83 944, did some work and replaced the clutch and flywheel, was running great, then i turned on the AC and was fine, blowing hard cold air, then after like 5 mins of use the airflow of the AC became such as the fan just being on. Not sure if the AC compressor broke or?
August 23, 2014
  Followup from the Pelican Staff: You may have a line that was stressed during the clutch job that failed. I would have the system leak tested. - Nick at Pelican Parts  
juanka993 Comments: Hi. I have 993 97' and I refilla little 134 , and now I dond have cool air.
August 18, 2014
  Followup from the Pelican Staff: Could be overfull, not allowing the compressor to come on. I would have the system evacuated and leak checked. - Nick at Pelican Parts  
Diverjoe39 Comments: My 86 911 has the large bump on top of the evaporator box cover. Does the evaporator motor you sell fit my box? The diagrams all show the pre-86? box top with the small bump.
August 15, 2014
  Followup from the Pelican Staff: We should have something that will work.Give our parts specialists a call at 1-888-280-7799 and they can help figure out which part or repair kit you need.
- Nick at Pelican Parts
 
BF Comments: Have a 2003 Cayenne just added some freon and now the compressor isn't kicking on. ???
August 12, 2014
  Followup from the Pelican Staff: How did you determine it needed refrigerant? It may be overfull. If system pressure is too high, the compressor will not run. - Nick at Pelican Parts  
JonathanEngr Comments: I have a problem with the a/c on my 2000 911 C2. It works 100% of the time when I start my engine, but after running for a bit the a/c stops blowing cold air. Sometimes this happens in a few minutes, sometimes much longer. Running the fan to full and/or the temp to LO sometimes works, but not always. And when the air is working, it's very, very cold. I would like it to be consistent so I can use the AUTO setting. Any thoughts on this intermittent issue?
August 12, 2014
  Followup from the Pelican Staff: Are the condenser fans running? If not, the system pressure may get too high, turning off the compressor. - Nick at Pelican Parts  
Rue Comments: Porsche 2005 Cayenne V6.

I was driving and had the a/c on. The a/c just stopped working. No air blows when it's on. Please advise.
August 8, 2014
  Followup from the Pelican Staff: This could be a faulty blower motor or blower motor final stage. - Nick at Pelican Parts  
Richard Comments: Hello, I have a 2008 Cayman and the front AC blower/fan sounds as if its about to die. In this model is the blower located in the front trunk or behind the dashboard? If it's the latter, how long would it take to replace the unit assuming it was handled by a professional?
Many thanks
July 21, 2014

TW Comments: I own a 2006 Cayenne S w/2 zone A/C system. The drivers side & passenger side front air vents no longer blow any air. Center, top & floor vents blow good cold air. Additionally, the passenger side vent also makes an annoying "Tick, tick, tick" sound at low fan speed then the ticking noise gets faster as the fan switch is increased, stopping the sound at full speed, returning as the fan speed is lowered. Any thoughts? Is it an easy DIY?
July 12, 2014
  Followup from the Pelican Staff: The ticking could be something jammed in the fan or a blend door actuator. The lack of air flow lends me to feel a blend door may be at fault. I would say the diagnosis alone is not an easy DiY. Once diagnosed, you may be able to swap out the part, depending on what it is.- Nick at Pelican Parts  
jas Comments: Hi, I have a 2004 cayenne. No matter what the heat setting is on either side it blows out hot air. What can cause this problem please?

DomP Comments: I have a Porsche 986 Boxster 3.2s. The AC has stopped working again. I have replaced the refrig with 134a - pressure was 0, but fills up 40 ok no probs. However no cool air out the front. However the strange thing is that on the front passenger side in front of the wheel - cool air is blowing out But baking in the cabin No fault lights. Also I had the water squirter cable drop out from inside the wheel arch. Not sure a bump could have loosened a cable. Also pressure drops to zero after a day or so.

Sweating in Missouri. Comments: Hi. Have a 996 02' carrera 2. After not driving it all winter, I took a loop around the neighborhood and turned the AC on. About 5 minutes in I heard a loud grinding-like sound behind me. I came to a stop and it went away. Then as I drove forward again it got louder, and increased in frequency as I slowly gained speed up to 15mph. The noise seemed to match the rpm of wheel rotation, not engine rpm. As I reached 15mph the noise abruptly stopped, as if something broke loose. But that's when the AC stopped being cold. There is still plenty of air flow from the vents, but now it's just slightly-chilled air, and now there is a low humming noise when the AC is turned on. Any suggestions? -Sweating in Missouri.

May 15, 2014
  Followup from the Pelican Staff: This is an odd one. I would check the blend door for heat and cold is in wrong position. If so, when the fresh air door closes, air flow may reduce or become limited. - Nick at Pelican Parts

May 2, 2014
  Followup from the Pelican Staff: I would check the blower resistor at the blower duct. It is the easiest place to check if the signal is getting from the blower speed switch to the blower motor. You will want to confirm that the switch still sends a signal to the resistor with the A/C on. MOnitor it when the A/C is off and the blower is working to determine the right test values. - Nick at Pelican Parts

MannyV Comments: I have a 1998 Porsche 986 Boxster. AC was great till I heard a sound like the one made by a loose V belt. I stopped the AC, started again and everything was OK. Cool air was coming out. Few days later same thing happened, did same thing but this time no more cool air was coming out. Removed the trapdoor behind the seats and found that something had melted in the compressor clutch. Started the engine, connected the AC and saw that the clutch did engage and worked for a few seconds the the center stopped turning and a burned rubber smell started to come out of the clutch. I am sending a picture of what I found. Could this be that compressor is damaged?
February 28, 2014
  Followup from the Pelican Staff: Either the compressor clutch has failed or the compressor itself seized. See if the center bolt on the compressor rotates, if so, try replacing the clutch assembly first. - Nick at Pelican Parts  
metritype Comments: Re: 1985.5 944 Air Conditioning Operation - Just had the control unit rebuilt and I think the operation of the a/c is now different. I recall that, if the fan switch is set at zero and the a/c switch is pushed in, the a/c does not start to operate. In other words, the compressor will not come on in the zero position - only in fan positions 1, 2, 3 and 4. Am I wrong?

danmanporscheman Comments: Hello, I have a 1986 930 turbo with a new a/c compressor, the fan in the car would always come on and blow normal lukewarm air anytime it was switched on. I put R134 in the system without knowing if there was any old/stagnant r12 leftover, and also did not have the system vaccumed out first, but it blew cold air for awhile, and i drove it around town, it was very nice. Then when i went to park somewhere, turned the a/c off before turning the car off, left, came back about 20 minutes later, turned the car back on, switched on the a/c, it blew cold like it was before, then it suddenly stopped blowing period. it doesnt blow even normal air when the knob is toggled on. Pleas help, what could this be the cause of? a relay going out? the r13 freon? I'm at a loss

CrimsonArchangel Comments: I just picked up a 1986 944
the AC has already had a r134 adapter attached to it, vacuumed the system out, put in enough 134 till the compressor I believe was supposed to kick in and take the rest of the can. after hot wire here and there and to the main battery we noticed the clutch was removed. not sure if the compressor can even be tested without a clutch so probably should just buy a new/rebuilt compressor.
i am seeing a lot of 82-95 and 87+ compressors but 1 or 2 that say 85 1/2 - 86 but the sites that say their 87+ compressors will fit the 86. Is this so??
and is it realistic to buy an aftermarket compressor that says comes with the hoses and clamps to convert to fit the 944, hoping the year is correct in their conversion kit?

Dive964 Comments: Have just had the A/C repaired on my 1990 964 C2. The A/C guy told me that it's best to leave the A/C switched on permanently regardless of it being summer or winter and just use the climate control to control the temp in the car. I realise the A/C should be switched on occasionally to stop 'drying out' but surely things like the compressor will last longer if not on the whole time? What are your thoughts?

September 2, 2012
  Followup from the Pelican Staff: If all the fuses are OK< you may have fried some components. I would focus on one item. Say the cluster. Check if power is getting to it, then check the grounds. If it is missing, you have to find the open or blown fuse, it power and ground is present, you shorted out the cluster. - Nick at Pelican Parts  
Trying to be helpful Comments: spyglass Comments: 1987 944 Porsche Aircon. Fuse #29 7.5 amp keeps blowing. Tried 10 amp but that failed after 2 hours. YOU ARE VERY LUCKY YOUR CAR DIDN'T CATCH FIRE IN 2 HOURS! Any ideas what to check or what may be at fault would be appreciated. MATE! Never, ever put a bigger fuse in if a smaller rating fuse that is supposed to be there blows. Fuses blow for a reason and it is not because of the fuse! A fuse is there purely to protect the rating of the wiring. NOTHING ELSE. If whatever you are feeding is faulty it is drawing too much current and therefore the fuse blows to protect the current carrying capacity of the wiring. By putting a bigger fuse in you risk two things! Firstly it wont blow when its supposed to which is STRAIGHT AWAY, and you have proved that. The second thing is if it doesn't blow, you have now INCREASED the rating of the fuse PAST the rating of the wire where it will CATCH FIRE. So, when a fuse blows, check the rating. If it is the CORRECT rating it blew for a reason! Look for the reason! Never, put a bigger fuse in. You may as well put a roofing nail in then call the fire brigade.......

Royal Comments: 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?

  Followup from the Pelican Staff: I would have the system leak checked. Repair the leaks. Then replace the receiver/dryer and retrofit to R134. You should be OK. - Nick at Pelican Parts  
LuisPorsche Comments: 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!

Harvey Comments: 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
  Followup from the Pelican Staff: Yes, I prefer to use nitrogen when leak testing. I use it to pressurize the system while looking for leaks using a detector. Once found, I repair them. I would suggest finding a shop that uses this method. I bet you have one major leak and that is all. - Nick at Pelican Parts  
chris ghiatis Comments: 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
  Followup from the Pelican Staff: I would avoid stop leak. It can plug the system.

The staining might be a leaky hose. I would have the system leak tested. Once you confirm where the leak is, repair it and recharge. - Nick at Pelican Parts
 
shovelhead Comments: 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

sweden Comments: 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
  Followup from the Pelican Staff: Pressure when? If you mean when filling it, you add refrigerant by the ounce, not pressure. - Nick at Pelican Parts  
sjphd Comments: 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.

May 3, 2011
  Followup from the Pelican Staff: Are you referring to the blower motor? It may be worn out. i would check that it is getting good power when on HIGH or when the problem is present. - Nick at Pelican Parts  
Robert Comments: 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
  Followup from the Pelican Staff: Yes, this sounds like a faulty blower motor resistor. - Nick at Pelican Parts

Tkid007 Comments: 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  
2porscheguy Comments: 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  
Jimbo Comments: 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  
lundy Comments: 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

go282 Comments: 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  
Piaf Comments: 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: 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  
Gavin Comments: 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  
Jeff Comments: 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  
Ellis Comments: 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.

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  
BobL Comments: 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  
dawg Comments: 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  
dawg Comments: 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

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 928 Comments: 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  
bill Comments: 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  
mjsluvs2wrk Comments: 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  
Boxerboy17 Comments: 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

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

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
March 4, 2010
  Followup from the Pelican Staff: If you add a small amount of water to the fresh air intake, does water come out the bottom of the vehicle? This is a quick way to determine if the drain is plugged. You may only need to treat the evaporator with a cleaner to remedy the odor. - Nick at Pelican Parts

September 17, 2009
  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

jbsf100 Comments: 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
