Golf IV / Jetta IV :: 2001 - Cooling Fan Not Working Properly
Dec 17, 2015
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?

My problem(s) are as follows:
I recently got a 2001 VW Golf 1.8T from a buddy in the Marines. He delivered it to me at my home almost 4 hours away, as described, reportedly without any issues. I got all of the paperwork transferred so that my wife could have a solid daily driver, only to discover ...
1) The vehicle in question was apparently used by a car audio company local to him, who has done some serious screwing with the electrical system in order to incorporate (and then remove) their crap.
2) When shifting through the gears, and coming to 4th gear, you get a couple of seconds of initial acceleration, followed by deceleration and RPMs falling, which in turn leads to the speedo dropping.
3) The same thing happens in 5th gear.
4) The only option is to downshift to a lower gear, which she did, and was apparently cruising along at 60 mph in 2nd gear, as 3rd gear was behaving the same way as 4th/5th upon downshifting. I'm not a mechanic by any means, but I'm pretty sure this is a BAD thing .

Heat blows warm at best and A/C isn't all that cold. I want to believe its a blend door issue and dive into it this weekend and fix it but there isn't a single piece of foam coming out of any of the vents. Of all the systems on the car HVAC isn't my cup of tea I don't know anything about it. What else could be the problem?I can live without A/C but the heat things must be fixed.

My, auxilary cooling fan isn't working. However, the bigger (primary) fan is working fine. Fuses, looks ok and i see clutch is engaging fine too. well, the a/c is working but not as it used to before. Its cold but very faintly. I suppose this could be because of the not working auxiliary fan.

I recently picked up an 02 Golf with a 2.0/5-speed. It's just a plain-jane model without all the bells and whistles. My fans and A/C aren't working. I can deal with no A/C but the cooling fans are kinda important. I did all of the trouble shooting. Both fans work on low and high when jumped at the radiator temp switch so my fans aren't the problem. I replaced the temp switch with no change. My OBD-II scanner shows that my actual coolant temperature was about 10 degrees off from my temp gauge so I replaced the temp sensor too. The timing belt and water pump were both changed about 5K ago.
I borrowed a "good" FCM from a buddy's car and that didn't work either. I went through the troubleshooting diagnostics for the FCM harness and see that I do not have continuity between T14/14 & T14/5 on the harness side. This indicates that the "F38 Ambient Temp Swicth" is possibly my culprit. Everything else checks out good on the FCM harness. Where is this switch located? I've searched online and found nothing specific to my 02. For the sake of testing can I jump these 2 wires for continuity to simulate a working switch? From what I've read this ambient temp switch disables the fans and A/C when air temps are below a certain temp. My next step is going to be wiring in a variable speed fan controller if I can't figure this out .....but I'd rather not get in to that if I can get the factory setup working.

I have a quick question, I got a 2005 mk4 gli, and when the cooling fans go on, only one works, the other one does not, I checked the fuse and its fine.

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.

I have a 2001 jetta 1.8 turbo. when I turn the car off the cooling fans stay on and kill my battery. Ive been told it could either be a relay or temp sending unit but i dont know what one to tackle first, also my coolent temp stays way low almost as if the thermostat is stuck open.

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 have a brake problem on my 2001 Isuzu Vehicross that has mechanics at 3 garages stumped.I bought this SUV in Dec 2013 and drove for 9 months with no noticeable problems.
At PA state inspection in Sept 2014, all 4 brakes and rotors were replaced. Since then the brakes slowly started to not engage when the pedal is first pushed. It progressed until they didn't engage until about an inch from the floor.
In Nov 2014, the brake lines were checked for leaks and bled twice. Each time they worked fine for a few days, then started to not engage again. A friend suggested maybe it was not brake fluid in my brake line. A mechanic assured me they contained brake fluid. Needless to say, I did not drive this SUV much over the last several months.Then in July 2015, another mechanic thought it was the master cylinder so I had that replaced. It did not fix the problem.
It has progressed to the point where I can feel they are engaging when the pedal is close to the floor, but not very strongly and I travel further & further until I finally stop.There are no dashboard indicators, nor codes on a diagnostic computer showing a brake problem. I have never seen brake fluid on the ground under the vehicle. What might be causing this brake problem?

I have this weird problem with the cruise control of my 2002 elantra gt: I cannot set the cruise control at 30 or 40 mph, but I can do it somewhere above that (just went to the highway and set it around 60 mph). What could be the problem? Do cruise control systems need calibration or would I have to replace it?

My car is a 01 b5.5 1.8t 5 sp manual transmission. it has 170xxx miles on it and for some reason, it won't start. last year I had some trouble with it where it would either start right up, or nothing at all, and it's doing it again, except now it just won't start at all. you turn the key, the battery engages, and all the electronics work (aside from the power windows, and sunroof), but there's not even an effort by the engine. it's like I didn't even turn the key. All last week, it was doing it, but I would just disconnect and reconnect the battery and it was fine. yesterday morning it just stopped trying. What could be the issue? it's really weird....also before this, I've been having a lot of trouble with once the cars been running for about 5 minutes or so, the power windows and sunroof decide to not work. but when I turn the car off and back on their fine. its odd. also, the alarm horn will honk randomly a single time. my electronics are all messed up

2001 jetta 4 dr. 2.0 gas
The other day I was driving and the air just quit. No screeches bangs or anything. I checked all the fuses and realized my main fan wasn't working.
I replaced both fans but still no air. When I push the button on the dash for recirculate my brake light on the instrument panel comes on.

My stereo fuse had blown off and while trying to find it, i removed all the fuses one by one to see which one was blown. I found the fuse, changed it, stereo was back to life. Only problem is that right before removing the fuses the car was driving normal. After checking the fuses the car seems to take longer to start; starter keeps turning for twice the time it did before. Also it seems as if the turbo is not even there. Btw the car is a golf mk4 tdi 150 bhp 2001 model

So I just got a new car tonight (01 Jetta 1.8t) traded my tdi for it. They failed to tell me about the lighting problem. The dash light (blue ones that light up whole dash) only work sometimes. Don't work when headlight switch is on (have euro switch) but they will work sometimes if you put the left blinker or hazard lights on. Illumination for window / lock controls are glowing red, same as all the buttons by the vents up top of the radio, ac / climate control lights not working. They did end up telling me that they swapped the other car they had (2L golf mk4) and they swapped in that dash and it worked no issues. Do I need a whole new cluster?? Or is there something I can try to fix it?

I had some Helix HID lights installed (opdparts). The lights all work except the driver side low beam. Here are two short vids showing problem:
The light in question also will flicker if I hit a bump. I tried to research solution but i'm ignorant on this matter.
Also The adjustments do work for the light. I can raise/lower or make beam go left or right.

Just the other day my remote began to stop unlocking my doors at all? And the hatch button works most the time along with the lock. Locking it always sets the alarm but on occasion it doesn't actually lock the door. Am I just out a whole key..

So I bought an 01 GTI last week with a decent amount of things pre-modified including a Jetta front end swap? Anyway the guy I bought it from knew absolutely nothing about what had been done to the car other than the fact that there was an HID kit installed and it was set up to run high beams only.
I figured I'd remove the HID's until i drop some cash on a pair of nice projector housings. I removed them and plugged up some nice sylvania bulbs as per the OEM standard 9007, and figured I'd have no issues... They are still stuck on high beam only... What could be causing this?

I just got a 2001 Jetta 2.0 (I know slow but I needed a work vehicle) and the dash lights and passenger rail lights don't work, the check engine light, fuel light, all those type of lights work, but the speedometer and blinkers and that stuff don't work, and then the blinker works in the back but no break light. I'm pretty good mechanically but when it comes to electrical stuff I'm completely stumped. What it could be? I haven't looked into anything due to just getting it last night and having to work this morning.

My 2001 alero 3400 engine is getting hot again this alero is running with a 2001 impala engine run great for few months, replace radiator, hoses, thermostat and suddenly coolant start leaking in the overflow, fans not working even with ac on, i replace the etc sensor and did not work, the fans turn on when I disconnect the etc sensor so i think the fan motors are ok. I got one pcm module from the salvage yard in case I need to replace it but I read that only the dealer can reprogram the computer system because vin number issues....
