I don't see anything in my 2010 owners manual about the air cond compressor cutting off under throttle. Yet on my 2007 Audi, it stated such in the owners manual. I'm wondering if it still has this excellent feature in the base Golf.
View 7 RepliesCar's at the dealership, AC compressor died. Car has 22k miles. They stuck me in a Cobalt. Base model. Complete with manual windows and door locks.
View 6 RepliesWell, car is back in one piece now but I'm having problems to make my AC to run again. We change the condenser due to broken line, and now the AC lines are empty, yesterday when trying to refill the R134 freon gas, the AC compressor fails to run. I notice the compressor connector was not plugged in, so I tried to reconnect it and fail to lock the two parts together, for some reason the plug is not plugin !!
Maybe a broken tab on the male socket, i don't know. Other than that, i can't diagnose or make my AC compressor to go on again, what to try ?? All i know is that the compressor is good and should run again, it didn't get any damage from wreck.
Also the airbag light is on, even when no airbag popped out when I hit the curb, anyway, is there any quick fix to that light, maybe a reset or something, what should I inspect for to find the problem.

Not getting any cold air. A/C compressor is not spinning. Fuses look ok. What else can I check before I take it to a shop?
View 8 RepliesAC compressor won't kick on at all. I know the system doesn't have much refrigerant (just replaced the line that runs from the expansion valve to the bottom of the drier, the drier itself, and the condenser)..
Evacuated the entire system with a pump. Tried putting refrigerant in and the pressure on the gauge goes up immediately into the yellow/red...jumped the connector on the high pressure switch and the fans came on, shouldn't the compressor kick on too?
Checked the 14 pin connector on the fcm for 12V...PIN number 8 is barely seeing any power which leads to no power getting to the compressor...
The dealer diagnosed my a/c as needing a new compressor and clutch. I had an a/c specialty shop install a remanufactured compressor and clutch. however, they could not get the compressor to kick on. I checked all fuses (all are good).
I checked the compressor continuity (good, 0 ohms). I checked the plug where the compressor clutch plugs in (it reads 12 volts). the funny thing is, it reads 12 volts anytime the engine is running (even if the climatroinc is turned off). I am definitely not an a/c expert and really don't know how this stuff works.
In my 2001 2.0, my AC has been blowing hot air for a while now. It was intermittent at first but now is constant.
The compressor runs without going off when the AC is switched on. I can tell because I see the compressor clutch engaged and spinning.
I tested with AC manifold gauges and these are the readings I got.
Engine off : Low is 0, High is 135
Engine on, AC on full blast after running 10 min at 1500 RPM:
Low is 4, High is 135
Looks pretty bad.
I am trying to figure out why my AC is not working. Both fans are coming on and the AC button is light up but it is not blowing cold. The charge was checked and it has a good charge. The compressor appears to not be engaging. I checked for power at the electrical connector for the AC compressor and my voltmeter is showing voltage between 3.1-8.3 volts. It jumps around between that voltage every few seconds. The fuses have all been checked and are in not broken. What else should I be checking?

so far i have replaced 2 fans ; thermal switch in radiator ; ran all the tests i can find ; all fuses and relays seem fine ; jumped compressor and it engages .
key on & car NOT running there is no power to the compressor.
I wanted to check the low pressure switch but every test is for a 2 wire set-up.... mine has 3 wires. which wires do i jump?
I have recently bought a R32 2008, and when trying to turn the AC I don't hear the AC compressor clutch clicking, the fans are running normally (radiator fans ). What should I check ? Someone told me that maybe it's a compressor problem, and another one said that if the refrigerant gas is low the clutch won't be engaged.
View 3 RepliesI have a 2004 Jetta wagon 2.0. About 2 years ago my compressor was replaced with a used one and the a/c was working perfectly fine. Last year the air from the a/c began to get warmer until it completely stopped blowing any cold air. A couple of weeks ago we checked the freon lines and they had plenty of pressure in them. We also checked the fuses in the car and on top of the battery along with the fan control module. The compressor spins from the serpentine belt but the clutch does not engage and there is no power in the wires going to the compressor. There is power at the high pressure switch but the condenser fan does not come on unless the switch is jumped. Could the culprit be the ambient temperature sensor?
View 9 RepliesOk My Ac doesn't work on my 05 Jetta 2.0 blows hot air. These are the steps taken so far to no avail
_Function test A/C System_ A/C is not cold_ Recover A/C, System was low
_Pressure test system with nitrogen for leaks_No Leaks Found
_Charge system and add dye
_Test operation
_Found compressor not cutting in_ Inspect for ground at compressor_OK
_Test for power at compressor_NO POWER GETTING TO COMPRESSOR
_Inspect fuses_OK
What's going on with this and what the next steps might be?
I have an 02' 2.0 Jetta Wagon, and the A/C is having some issues. Since I know close to nothing about A/C systems, I took it in to a few places to have it looked at. I've had the whole system Evac'd and recharged, and have had the low pressure fitting replaced (apparently there was a slight leak there), and the system is still not working.
The A/C worked fine when I first purchased the car a few months ago. Shortly after my 800 mile trek from Oregon, back to home, the A/C started to only work intermittently. The compressor would engage, then disengage, repeat...It seemed like a bad idea to keep trying to use it in its sad state so I stopped using it altogether. As I said, I had the system emptied and recharged, but it still only works intermittently. It sort of follows a pattern where upon start up it works longer, and switches on and off at shorter intervals, until it doesn't engage at all.
There are no strange noises from the compressor, and when it was hooked up to the machine, it proved to be performing its function well.
Compressor does not engage, and my fans do not come on when I turn on the A/C. They do come on low speed when I jumper pins 1 and 2 on the temp switch plug, but they do not come on high speed when I jumper pins 2 and 3.
I have replaced the FCM with a new one, as well as a guaranteed working used one; neither one changed anything. I assumed right away that it was the fcm because my original one has a hole eaten through it from battery acid.
Compressor clutch ohms out within spec, and it will engage if jumpered.
I have a 2003 2.8 GLI and my compressor clutch will not engaged i provided the clutch with a direct power and ground from the battery and it engaged. i also went to the junk yard and got a couple of Fan Control Module ($4 each) and it still does not engaged.
View 3 RepliesGolf 2.0 ... Finding the location of the AC Clutch/Compressor relay location. On the TDI its behind the the dash and I looked on mine and it doesn't seem to be the same. I've seen a thread where some said it was under the battery? Where it is and what number will be stamped on it. Another thread said it should be behind the dash and number 385 or 358, I looked and I don't have those numbers back there.
View 2 Replies2002.5 VW Jetta GLI VR6 24V 6-Speed. Barely accepts a small can of Freon from full empty, and pressure goes to over 100 psi in the red, compressor does not kick in, idle fluctuates with A/C button on, small fan kicks on fine, some air pump turns on and off with the erratic idle and sounds like shot of compressed air. When I turn the A/C button off, idle comes back to normal and that psss sound is gone. I already changed compressors and that made no difference. Video below.....
View 5 RepliesClutch for the AC Compressor will not disengage even with the AC off. The only way I can daily the car is if I disconnect the power from the AC Compressor at the compressor itself. Seems the AC compressor has a constant draw if it is plugged in.
Plugged = dead battery...
Unplugged = good battery...
I'm getting ready to rip the damn thing off the engine and calling it a day, but that would defeat the purpose of me buying a new compressor.
I have a 2002 Jetta 1.8t and the A/c doesn't work. I took a look and I know that the clutch/compressor does not engage. also, the rad fans do not turn on when I have the AC on in the car. all I get is hot air. I tested the line and there is no freon in them whatsoever. which is why the compressor is off. however, I can't add any freon without it working. I checked the fuses on the side of my dash and on top of the battery as they seem to be ok. Also, I was told that I just need to replace the compressor with a new one and I should be good to go. Is this true? It will be an easy fix if it is.
View 13 RepliesI have an issue with my 2003 golf 2.0 ac I've done everything that I cloud thing of to check but I still have this issue so here it is. The air coming out of the vents is warm, compressor Clush turn on but doesn't kick off. I hook up ac gauges and it reads 70 on low side and 155 on high side with an ambient temperature of 80. The system has freon, I check fans and they are on when compressor kicks in all relays and fuses are fine.
View 8 RepliesWeird A/C issue that started yesterday. Had ac on all morning, start my car after lunch, a/c runs for a few seconds, hear a squeak (like a belt sticking) no more a/c. Moving the temp knob makes no change just all hot air. Both fans engage, compressor and what I believe is the clutch engage, hoses get cold, and no CEL's. Really stumped here.
