99 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 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 picked up a 2004 GTI not long ago for pretty cheap because it had a few issues. I am working my way through them. However, having 3rd gear issue.
All other gears are perfectly fine but there is way less play in the shifter in the 3rd gear position and I have to hold the shifter in position until the clutch is engaged (pedal up) to avoid the gear grinding. Once the clutch is engaged it stays in 3rd gear fine. It doesn't matter if I am moving from 2nd to 3rd or 4th to 3rd. Same deal. I have aligned the shifter several times using to proper procedures with no effect.
It never grinds 3rd with the clutch disengaged (so the synchro is fine?) and it will bang shift no problem. Oh and the clutch is less than a year old. It was installed by a shop before I bought the car. It's not really a big deal, but I would like to fix it. If I have to swap the trans that's fine, but need to figure out if it is a trans or linkage issue first.
I bought a 2005 Ford Taurus last month with a bad A/C clutch. I had a friend, who says he knows about such things, replace just the clutch. He says he lost no refrigerant, which should be right. The A/C blows cold OK regardless of the ambient temperature, but the new clutch clicks in and out. I was of the opinion that this was caused by a low charge.
My (not always right) friend thinks it's normal, due to the cooler weather. I THINK the compressor should run all the time, and the car's interior temp is regulated by the flapper doors. I have no way to capture the present charge and weigh in the exact amount needed. I have accurately weighed in an additional 8 ozs, with a good digital scale, and it still clicks in and out. I have readings of 125/25, but the outside temp is only 50F this morning.
What readings should I see at 50F? Do I still need more R134a?
I was thinking my AC clutch has too much gap and was gonna do the "fix it" listed in another thread. However, my clutch wouldn't engage like it states needs to be done. The only time my AC blows cold is when it's cold/cooler outside OR I rev up the RPM's but it hardly stays engaged. I had a friend do a few diagnostics on it, with a paper clip (assuming he did it right) he feels my clutch is bad. But I've read the clutch is either good or bad, works or doesn't work, no in between.
Next, it doesn't seem to blow as hard as it used to. I replaced the blower motor last summer, but even before that, it seemed to not blow very hard. If I have it on low, it's very hard to feel it. With a crew cab and 2 little boys seated in the back, they often end up sweaty and miserable, no matter how far we go. I've read the orifice tube might need to be replaced, or something needs to be cleaned cuz it's dirty or clogged like the orifice tube. But I can't remember what.
I need diagnosing why my A/C isn't working. I'm wondering if my clutch staying engaged has burned up my compressor before or after my clutch went bad. I don’t think it’s the air gap issue because I took my clutch off and checked and there were zero washers. I guess somehow I re-installed it with no washers maybe the last time I fooled with it.
I've only knew to check the air gap trick and when that didn't work, I wasn't sure what my next step could be. I tried looking at the high side pressure switch connector to see if it was burned up and it looked ok.
Can track down if my compressor is still good and replacing my clutch is the only thing I need to do or if I need to replace my compressor? Or if there's something else that's totally unrelated that I need to check?
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 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 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've been noticing my GTI has been making some weird noises, especially after only have 380 miles on it. When idling with the clutch engaged, it makes a rattling noise that goes away when depressed. There's also a rather loud sound coming from the timing belt and just underneath the plastic engine cover. I'm hoping it just needs breaking in, but I'd just like some reassurance that it's nothing serious.
View 8 RepliesWithin the past 2 weeks I've been noticing that when I shift hard into 2nd and 3rd, I manage to grind the gears slightly. At first I thought that maybe I wasn't engaging the clutch fully but after enduring rush hour traffic in the hilly streets of SF yesterday, I noticed that I could replicate the grinding at a full stop with the clutch fully engaged which makes me think that maybe my clutch is going bad.
I'm a bit unsure since the car still pulls up the hills like a champ (maybe it could be pulling harder?) and need to point out tell tale signs to look for when your clutch is starting to fail and requires replacement.
If my problem is not due to clutch, what could it be? If it is, any good place in bay area to take the R? I plan to replace with stock set up.
Currently I have stock clutch w/ +73k miles. I did have an episode where a car transporter managed to make thick grey smoke pour from my clutch due to ineptitude so clutch failure would not surprise me.
I currently own an mk6 gti with a manual trans... as of late I've been noticing a rattling noise when the clutch pedal is not engaged.. once engaged the rattling stops completely .. it seems to be getting louder and louder .. I am worried this could eventually turn into something worse than just a rattling noise .. i had a friend mention it could be the "throwout bearing" ..

Obviously an electrical issue, no way all these codes spring up all at once for separate reasons. Any fuses, relays, harnesses or grounds that relate to all or most of these problems.
Car has trouble at start up, takes a little longer to turn over. If I don't stay on the gas it will eventually cut off. Once I am driving its fine. Its only once the E brake is up, it will cut off right after the brake light comes on.
OK, here's the update so far.
- new battery
- all fuses fine in panel, all fuses fine on battery pack.
- am getting power to trigger switch upon engine crank (tested w lamp and volt meter).
- did the 'mechanics tap' on the starter motor body
Still no crank when key is turned, instrument panel/gauges light up as normal
So am I right in thinking that I've narrowed the problems down to:
1) bad solenoid
2) bad starter
3) bad connection between battery and starter
or have I missed something?
Also, is there a way to directly test the starter (or indirectly test the solenoid) by applying power to the starter?
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 touchscreen that the dealership provided me but with the catch that I've got to install it myself, pretty sure it has something to do with the state the previous stereo was taken out, all I'm left with are a cluster of wires none of which I know are for what.
View 2 RepliesI finished installing an auto out of a 1999 beetle into my 2000 golf. I used the beetle TCM now it wont shift out of 3rd. If I manually start in first it will shift up to 3rd but nothing past 3rd. I had it scanned with a generic scanner and these are the codes. P1780, P1783, P0725. I researched the heck out of this and I'm not sure what to do. Do I need to take it and have a vag com hooked up to make sure the ecm and the new tcm are talking? It seems others have had these issues and I thought it might be solenoids but that's not what's coming up.
View 2 RepliesOkay just installed a newer 24v into my existing 24v VR6 GTI both with 135k. I have heard the motor run before it was pulled and sold to which sounded fine. Upon receiving the motor I put new timing chains, guides, headgasket and new gaskets all around. The timing was right on the mark and I tightened everything up to torque spec and I'm getting this noise which sounds like it's from the timing cover area. A code just popped on which I'm going to scan as soon as I get my hands on one. The car was running great for about 20 minute and I shut it off then turned it back on about 5 minutes later and experiencing these scary noises. I tried pulling each individual coil with no results to get the noise away. What could this be?

My 2001 Expedition 5.4L sat for 2+ years and due to a new child, I put it back on the road late last fall. Last week, we had our 1st "must use AC" day and it didn't work.
I listened to see if the compressor was cycling and it never engaged. I picked up a gauge and r134a kit.
Outside temp was about 60F, I think my therm was showing 57F to be exact. When I checked the low side pressure with the engine off, the gauge reading was below 15. It made sense that the compressor wouldn't start at the pressure. I put in about a 1/2 can with the motor running A/C on max and it was showing 40, but still no compressor cycling. I then shut the motor down, let it sit for about 3 mins and restarted. This time, the compressor started to cycle, it was cycling quickly though, I'd say about every 3 seconds.
With the compressor cycling, the pressure would jump from 17 to 40. With the motor off, it would read 50. Still no cold air. I put in about 14oz of R134a.
I guess what I need to know is if I should I keep adding R134a until it stabilizes around 40, even when the compressor is cycling? Also, where should the static pressure be? It's sitting at 50 now. I've been told it should be around 80, but I'm thinking that might be dependent on outside temp.
BTW, I'm now thinking that the reason that I'm not getting cold air and the compressor keeps cycling is because I need to add a lot more R-134a. I think when the compressor starts and draws coolant, the low side pressure drops to low, causing the compressor to turn off. When the compressor cycles off, it sees the low side pressure at 40 and starts it up again causing the coolant draw and low side pressure to drop to low again. Am I right on this thought? It looks like I'll need to add another can to get the pressure to stay above 22 when the compressor is running.
One other thing... How much R-134a the system takes? I need to know because I have access to a vacuum.
