Golf IV / Jetta IV :: AC Clutch Doesn't Engage
My AC doesn't work right now, however, sometimes it works. It's very random, it doesn't matter if its hot outside or if its cool.
What happens is my AC clutch doesn't engage. when I turn ac on, it raises the idle for a second, and as soon as it does that, my ac compressor gets around 12 volts for less than a second, and the idle drops again. it does that in a loop.
My fans work fine, both high and low speeds, everything else works, all the fuses are good. I changed the pressure switch, didn't fix the problem. I also checked the ac coil and clutch. everything clicks and works. ground on the compressor is good.
Other odd thing - positive wire on the compressor constantly getting around 3 volts. What can it be and what else do i need to check?
Golf IV / Jetta IV :: Starter Motor Doesn't Engage Or Spin When It Is Very Cold
My starter motor in my 2004 Golf 2.0 doesn't engage or spin when it is very cold. By very cold, I mean below 5F.
The battery has plenty of juice, and jumping the battery doesn't work. I turn the key to "start" and nothing happens. When key is in the on position, fans, wipers, etc all work fine. When the car warms up to 20F or so, everything is fine and the car starts.
Here's the funny thing. If I put a little space heater on the driver side floor to warm up the fuse and relay panel, it starts with no issue.
I don't know enough about the interlocks between load reduction, starter motor, ignition switch etc to make a good guess as to which relay (if any) may stick in extreme cold. It's a tough problem to diagnose, because I can only experiment when it gets REALLY cold, when it isn't very fun to experiment anyway. I don't think it's the piggy back harness, because the wipers, horn and fan all work.
Golf IV / Jetta IV :: AC Clutch Does Not Engage To Cycle Freon So No Cold Air
I had to replace one of my Ac lines. The skinnier one.I have never seen the air work in this car. That line was broke since I have owned it.
I went to try and fill it today with r134. I have as much pressure on the low side as I can put in. (55 says the cheap gauge) But when I turn the car on the clutch does not engage to cycle the freon so no cold air. What I know,The fans do not turn on when Ac button pushes.The connector to the compressor only read 4v. I cannot get any number on the high pressure switch connector. (3 pin)
I don't know if it just doesn't turn on because nothing in the high side? Is there a way to bypass? I read jumping the switch is a bad idea.
Golf IV / Jetta IV :: 2003 - AC Compressor Clutch Won't Engage - Low Voltage?
I 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.
Golf IV / Jetta IV :: Clutch Disengages Then Engage Again For A Split Second When Accelerate
So I just bought a 2000 MK4 Jetta for a $1000, its been ok, replaced the breaks, rear calipers, swapped in new headlight socket, swapped in amber tails, new plug wires, new drive belt, water pump/ timing belt all new.
Car has 173,xxx and i drive in pretty bad traffic daily, there are times when i am going to accelerate and between 2-3k RPM it feels like the clutch disengages then re-engages for a split second. then continues to drive normal, happens 2nd, 3rd, and 4th. Is this the clutch slipping? will it be fixed if i were to order a new clutch kit? I am on a budget and do all my own work, so i can't afford to buy a new clutch kit and have this not fix the problem.
Also, the car gets a little wiley on the free way, feels like its the struts, but the steering wheel vibrates a bit, i just found out the PO had different rims on the car before. So the tires might need to be balanced. I JUST Ordered new Racelands hopefully to stop the creaking/bounciness of the suspension. How to get this steering in check.
Golf IV / Jetta IV :: No Dash / Radio Lights And Cooling Fan - AC Clutch Will Not Engage
Just picked up a 2004 MK4 Jetta GLS 2.0 for really cheap.
As the title reads I have found some issues with the car after giving it a once over.
Dash/Radio lights - My Dimmer Switch is not getting power. I was wondering what the next step would be. I checked all the fuses and there is no issue.
Cooling Fan - I read about testing the plug and a CFM. Which should be done first?
A/C - I changed Electrical-Switch & Relay: A/C Clutch Switch and it did not fix the issue.
Ford - Windstar :: 1995 - When A/C Is Turned On Compressor Clutch Doesn't Engage
I have a 1995 Ford Windstar. When I turn on the air conditioning, the compressor clutch does not engage despite having sufficient refrigerant in the system. Jumping current directly to the compressor clutch will engage the clutch, so it's not the clutch. I suspect the relay for the compressor clutch inside the CCRM may be bad, but am not sure how to test it. I have a Haynes repair manual, but how to test this device?

2000 GTI
260,000 miles (60% highway)
2.0L 4cylinder AEG
All stock.
I have a new issue developing on the clutch of my car. When I fully press the clutch pedal to change gear, I hear cacophony of grinding, hissing and whirring noise, probably coming from gearbox. When I take my foot off of the clutch pedal completely, the noise is gone. half clutch has reduced amount of these noises. I had this symptom briefly one night two weeks ago and when I topped up oil, this was gone. Tonight, it is back.
Accent LC (2000-05) :: Need To Push Clutch Really Hard To Allow The Gear To Engage?
2001 Accent 1.5 GL 165K miles.
The clutch doesn't engage until it's on the floor. I have to push real hard to allow the gear to engage. It then shifts... sometimes smoothly, sometimes it takes a hard push of the gear shifter, or it grinds until getting into gear.
I've changed the master cylinder twice in about 3 years but those times the pedal had no spring and just fell to the floor and stayed. Now, the pedal has spring (I push it to the floor and it springs back) so I assume the MC is ok. I even bled it with fresh fluid.
I'm not sure if the tranny fluid has ever been changed. Would changing the fluid fix this problem or does it sound like I need a new clutch? I'm guessing it needs a new clutch (or corresponding parts) since I've had two MC's go bad in a few years.
The pedal, even when it's shifting smoothly is pretty non-responsive and still engages a little mushy (comparing it to my 2012 Elantra 6sp).
Jeep - Overheating - Weather - Cherokee - Clutches :: 2000, AC Clutch Won't Engage On Hot Days
2000 Jeep Cherokee Classic 4.0L, in Palo Alto, CA.
My air conditioner clutch stops engaging after driving in hot weather.
In hot weather (>80 degrees), when I first turn on the AC it blows nice and cold for up to 30 minutes, after which it gradually gets warmer and then hot air comes out. If I leave the AC on when it is blowing hot air, it will suddenly blow cold again (sometimes it takes a couple minutes for it to work again, sometimes it takes 30 minutes). Then the cycle repeats.The AC seems to be dependent on outside temperature: on very hot days ~95 degrees the AC will only work for ~5 minutes before blowing hot, 80 degree days the AC works longer, limited testing in cooler weather (at night ~60 degrees) AC always blows cold. When it is blowing hot air, the clutch on the compressor hasn’t engaged. When the AC is blowing cold, the clutch engages/disengages normally depending on how you set the temperature. I replaced the low pressure switch, did not change AC function. I recharged the AC, did not change AC function.Engine temperature reading always in normal range <210 degrees. Heater is working normally.
I’m pretty sure the clutch is getting the signals to engage. When the AC is working normally the engine revs slightly higher when AC clutch is engaged.Likewise, when the AC is blowing hot air and the clutch isn’t engaged the engine revs higher. And if I disconnect either the low or the high pressure switches the engine reduces to normal idling.
Golf IV R32 :: When Let Out The Clutch, Gears Grind But Will Not Engage
148,000 miles, and yesterday my R decided it would no longer allow me to use first gear. It sort of starts to go in gear, but feels kind of mushy, not positive, and if I let out the clutch, the gears grind, but will not engage. All other gears feel and perform normally.

View 24 RepliesGolf/GTI VI :: Loud Squeal Or Screech When First Engage The Clutch
I've been experiencing a loud clutch squeal or screech when I first engage the clutch after the car has been sitting for longer periods of time, overnight etc. It goes away after a few shifts and only returns after the car sits for a long period.
I brought it to the VW dealership since I'm still under warranty for a bit. After two visits the have come up with two hypotheses without any evidence. They claim to have not heard it or found anything wrong visually.
1) it could be a rear main seal leak. Or leak from somewhere on the tranny onto the cultch. When I first drive it is burned or wiped away. After putting on the lift they found no evidence of leaks. So hypothesis two:
2) Thy flywheel may be developing a bit of a patina of rust. After the clutch is engaged a few times, the rust is gone and the squeal goes away.
Golf IV R32 :: Stutter In Engine Which Continues As Clutch Begins To Engage On Up
2nd gear runs fine, but occasionally, when in first i have a real bad stutter in the engine and it continues from the moment the clutch begins to engage on up. The car just seems to jump or skip along rather than run smooth.. It occasionally will work itself out but other times will continue for 5 seconds at which i switch into second gear and everything is gravy from there. What the main root cause of this is? I don't want to get the wrong thing fixed which I've been trending on lately.

View 14 RepliesGolf IV / Jetta IV :: Intermittent AC - Compressor Would Engage Then Disengage
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.
Golf IV / Jetta IV :: 2003 - Compressor Does Not Engage, Fans Do Not Come On
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.
