Golf 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 RepliesI 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 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 RepliesWhere the magnetic clutch relay on a 2011 Camry is. I recently tried to refill the Freon in this car but after vacuuming the system and trying to add the Freon thorough a manifold set it does not appear to be getting added. I assumed this was a problem with the magnetic clutch relay. (also how I could get the part number for said relay).
View 2 Replies99 Jetta, installed a new AC compressor a month ago, has been working great, not clutch will engage for a few moments, then turn off for a minute, then engage again. Seems, like there is Freon in there by the gauge on the low side.
View 4 RepliesI found out that the bearing in the compressor clutch is the one making my car sound like crap... but I have been looking for it and everywhere I call they only sell the whole compressor that is expensive. I was thinking on get the clutch out and lube the bearing up or something but I don't know if I have to discharge the freon for doing it ... How to remove the AC clutch ?? Its an mk4 btw....
View 4 RepliesI got a 2003 GTI 1.8t and the AC air is blowing warm. With the car on, AC on and fans full blast both rad fans turn on but compressor clutch does not engage. Took it to a shop and the mechanic said the system was full of refrigerant but that the compressor was not getting the proper signal and there was an electrical problem.
I check the power at the compressor and it is reading about 7 volts, which is low correct? That should be getting 12-13 volts correct? I also check the pressure switch over by the passenger side and it was getting 13v. What to check next to start ruling out causes? Any quick way to determine whether this is electrical or a compressor issue? I am limited in my abilities as far as electrical work goes.
The A/C does not blow cold. The Compressor clutch does kick on and stay on The passenger side fan kicks on only (I think the driver side is toast but i need to test it to confirm) The system has 45psi on the low side
I did not check the high side as I don't have a gauge for it but will get one if I need to test that. So my thoughts are that my expansion valve is toast which is what expands the hot liquid and turns it to cool liquid so the A/C gets cold. I think this because it seems all of the other components work.
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 RepliesAbout 2 weeks ago, my jetta decided it didn't want to start. Was getting symptoms of a bad ignition switch prior to this. Could get it to start one by jiggling the key. Replaced the ignition switch and now could hear the starter relay click but still no start. Yesterday, installed a reman starter and got it to start once. Could here the solenoid click when trying to start. Was reading on here or somewhere that it my be my power control relay, so took the top off to look at it and it was fine. Battery was down about 100 amps so it was replaced and still no start. Going to go see if my vag com will talk to to the ecu. Thinking about pulling the starter out and having it tested.
MK2 are so much easier.
My wife drives a 2002 Golf 2.0L with about 214k on it at the moment. It runs really well and I'd like to keep it that way. Last week she told me that the car wouldn't start sometimes and that she would hear a buzzing noise when she turned the key. If she turned the key off and then on again the car would start. The problem was occurring more consistently as time went by and sometimes she would have to try to start the car four or five times.
I took a look at the car and her description was correct. The 53 relay under the dash was buzzing once the clutch was depressed and the key was turned, but the car wouldn't start. I took out the relay and put it back in and the car started fine. I swapped it with the other 53 relay in the panel (dual horns), and started the car a bunch of time with no problem. Then I gave the car back to her to drive to work. Everything was fine for a while.But now the problem is starting to return.
AC 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.
So I drove my car about a mile to a friend's house and when I went to start it back up 10 minutes later, I got no start and no crank. Just a single loud relay click from the engine compartment. Tow truck tried jumping it and then thwacking the starter solenoid to try and get it going. No dice. Battery seems all good.
Had some interesting things go wrong the day before which may be related to it. First, I was tracking my MPG and fuel trim on a highway trip and the trim and fuel consumption data just stopped coming in. Speedo and RPM data was still coming down the OBDII but I just assumed that my reader took a ****. Later that night I noticed that the lights on my climate control (the manual kind) went out. Tapped on it and it came back on, but only briefly. The bulb looks shot.
No engine strangeness on the drive over or earlier in the day. I drive it most every day. Has 215,000 miles on it.
I'm guessing either a short or bad starter. FWIW, I've also been experiencing the typical starter whine after starting. Was meaning to take it off and grease it. Not sure that has anything to do with it. I also tried rotating the crankshaft to make sure the engine wasn't locked up and it does turn, albeit not incredibly easily. It does have oil on the dipstick.
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 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 RepliesMy horns aren't working. I'm getting power at the horn fuse, but no power at the horn connectors. Where is the horn relay located? Is it in the fusebox under the hood? There are many relays, but none of them labeled "horn".
View 7 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.
