Golf IV / Jetta IV :: 2001 - Misfire At Idle - No Cooling Fans?
I have a problem I can't seem to figure out. My car has a misfire at idle. It has stumbled every once in a while at idle before while at Red lights. Now it does it all the time. Check engine light is on and I got 5 codes. P0300, p0301, p0302, p0303, p0340, and p0012. The last two are for cam position sensor. I took it outo and looked at it. Looks fine. I reinstalled it and hand cranked the motor with a meter hooked up and I am reading about 10 volts when it senses the metal ring going around. So I think that is good. I sprayed brake cleaner on all the hoses to see if the motor reved to hopefully find a vacuum leak. Nothing. I also noticed today that my cooling fans or my ac don't work. Now I have another issue to deal with. I checked all my plugs and wiring and coils also.

I need a way to make my both fans be on constant during track days, I know induction makes a fan kit for the mk4 r32 which works great but the controller in the MK5 is different and the kit don't fit.

2003 camry 2.4 ... This is what is happening, cooling fans will not come on except when the AC is turned on and they will stop working when the AC is turned off, otherwise the car will over heat.
This is what I have done...Replaced the fans (because the radiator fan was bad, after hooking them up directly to the battery). I checked all the grounds, including the one under the intake, checked the fuses, checked relays using 12vots to the relay and used a ohm meter to see if it made contact when activated, on the three fan relays. Replaced and tested the new radiator sensor using a pot of water on the cooking stove with a cooking temperature gauge and ohm meter. It tested ok.
Unplug the radiator sensor while the car is running, the fans will come on, but go off as soon as it is plug back in, even when the motor is over heating. Also replaced the thermostat.
What can I do next, before I burn the motor up trying to fix it? Motor just started running rough. Just now pulled up a code of the number three cylinder miss firing
Golf IV / Jetta IV :: 2003 GLS AC Inoperative / Cooling Fans Turn On Low
My 03 Golf ac is not working and i am looking for a wiring diagram/ troubleshooting chart. the cooling fans turn on low and I hear the engine surging like the compressor is trying to cycle but it is not.. When I jump the low pressure switch the fans go to high and no power to the compressor. I get a flash of power to the compressor but just a blip every ten seconds. I am trying to check continuity of the ac clutch but having a difficult time getting in there hot. I just bought the car and fixed light body damage on the right front but it was not even bad enough to hurt the washer bottle. Hard to believe the hit caused damage to the ac? AC seems to be charged with about 100 psi static pressure. Why are diagrams so hard to find?

My 2003 camry LE 4 cyl cooling/radiator fans stay on all the time. As soon as I turn the ignition key both radiator fan start to spin even though the car is cold and not on. I checked all the relays and fuses. Checked the voltage on the coolant sensor harness with ignition switch on, there is no 5v or the green pin is not grounded. I am clueless where to go next.

2001 Chevy Venture: Pins to 2nd fan in 4 pin connector burned and melting to connector. Fan seemed to work when wiggling connector. Bypassed connector and now does not work unless A/C is turned on Full Speed. Is connector important? What controls fans? Computer controlled? Seems to be larger gauge wire in one side than the other.
View 2 RepliesGolf IV R32 :: Cooling Fans Not Turning On And A/C Not Cold
The last few times I drove my car, I noticed the A/C didn't feel very cold. I checked today, and noticed that neither cooling fan comes on with the A/C on. My understanding is that both fans should be in LOW mode with the A/C on. Also, after idling for a while and even after doing some spirited driving and pulling over, the fans never turned on.
From what I'm reading, this sounds like it probably is either the fan control module or the fans themselves failed. Is the fact that both fans don't work in either high or low speed point to this being more likely to be a fan control module? Would this show up as a fault code on a VAG-Com scan?
Golf IV R32 :: Cooling Fans Continue To Run Until Battery Disconnected
After about 3 weeks, I finally get my 04 .:R32 back from the shop after getting a new fuel pump (long story there) and the mechanic mentioned the fans began to run and stay running when the key is turned to the on position and then turned off, key removed etc. I picked the car up tonight and repeated his claim turning the key to the on position and the fans kicked on and stayed on until the battery was disconnected. I am hoping there is an easy fix. What this could be? FCM maybe?
View 20 RepliesGolf IV R32 :: Cooling Fans Cycle On And Then Off Every Three Seconds When Start The Car?
Why recently the fan comes on when I start the car, then a few seconds later it turns off, then a few seconds later it's on regardless of outside temp or engine temp? Is this simply caused by a malfunctioning green coolant temp sensor? What type of electrical Gremlin causes our cooling fans to cycle "on" and then "off" every three seconds?!
View 1 RepliesGolf IV / Jetta IV :: 2001 - Cooling Fan Constantly Running?
I've decided the first issue w/ my new-to-me jetta I want to focus on is the cooling fan constantly running. I suspect this is potentially related to the temp gauge not reading anything, which I suspect might be because of the coolant temp sensor.
So basically, when I turn the key to on (I'm pretty sure it's on, not start), one of the cooling can comes on. It's the fan on the right side as if you are sitting in the driver seat. I've been looking at the wiring diagram for this issue as well, and the only other thing I can think of that isn't a computer involving issue would be the thermo switch. But it seems like both fans should be coming on in that case, and it's definitely only the one fan that is coming on.
Golf IV / Jetta IV :: 2001 - Cooling Fan Not Working Properly
I am having issues with our 2001 vw jetta wolfsburg edition with a AWW engine the cooling fans not working properly. I had a bad fan and replaced it and since changed the thermo fan switch and the module under the battery and still no luck. With the key off I can jump the fans via the plug for the fan switch only low speed works with the key off. with the key on i can get both speeds of the fan to operate. With the ac on the fans operate.. normal driving the fans will not operate. and the engine will overheat and fans will not go on. Any other relays or sensors that could be faulty?

View 4 RepliesGolf IV / Jetta IV :: 2001 1.8T Does Not Stay On / Stalls Out On Cold Start
When the weather gets cold, (lower than 45 deg. F) my Jetta does not want to stay running. It turns over and starts just fine but it does not like to stay on. When I turn the key to the #2 position I can hear the fuel pump fire up and pressurize the system. I always attempt to start it after that, and after 1-2 seconds of running, it seems like it chokes itself out. I have the new coolant temp. sensor (green top), my MAF has been replaced, all spark plugs are new with the correct gap (approx. .030"), new air filter, I run 93 octane fuel.
The worst part is, once the car is warmed up (After forcing it fuel and starting it over, and over, and over again) it runs awesome! I have had this problem since I bought the car (about 2 years ago). The owner told me about it and mentioned that he has never been able to figure it out either (trips to the dealer included). I have been dealing with it for 2 years, but it is getting much worse. Over the past 2 days I have not been able to get my car to stay on long enough to get it to move.
Golf IV / Jetta IV :: 2001 - No Spark When Engine Turned Over
2001 Jetta GL, 2.0L, 170k miles.... It won't start and it's not likely the fuel pump. After the car has sat for a while, I hear the fuel pump spin up when I open the door. It turns over just fine. I pulled a spark plug, attached it back to the wire, held it close to the head, and when the engine turned over, no spark. Is that still a valid test for spark? I haven't had to diagnose a spark issue for so many years, I don't know whether that has changed.

Here is my problem....the cooling fan will not come on, even with the A/C turned on. The A/C fan works fine. I've changed the fan for a new one and replaced the relay, and checked all the wiring, but nothing has changed. I've read other threads that have kind of the same problem and they mentioned the coolant temperature sensor. I don't have a problem changing it, but don't know where it is located.

This is kind of an odd ball problem since I have not encountered this before, but every time I turn my wheels full left or full right and start moving a really high pitched squeaking sound comes from the front of the car. Is it bad alignment or wear sensors on the brake pads rubbing? the brakes have a lot of pad left so i find that hard to believe.
