Golf IV / Jetta IV :: Ac Don't Work Anymore
So my ac stopped working, well actually I bought the car in the winter and never realized it didn't work until the summer rolled around. The clutched pulley won't engage and I don't know why. I checked all the fuses and checked the the pressure in the system and its all good.
Here's the weird part through. I put my multimeter on the connector for the compressor and it reads 12v whether I have the ac on or not.
Golf IV / Jetta IV :: Cooling Fan Won't Work On The Low Setting?
I have a 00 Jetta 2.0 AEG engine code and my cooling fans don't seem to be kicking on the low setting. I have changed out my FCM and have also checked the fans to see if they were burnt out and both fans work on both low and high settings. This is also causing my car to overheat but the high speed will kick on when the temp gets too high.

View 7 RepliesGolf IV / Jetta IV :: Remote Only Work Close To The Car?
Well our remotes only worked close the car and was driving us nuts. You'd have to be within 10 feet or so to arm or unarm the car. So i looked at the wiring diagram for the comfort control module and found which pin the antenna wire is at. Its pin 10 of the smaller connector (12 pin i think) and is a copper wound wire with a clear sheath around it. its the only one that doesn't have a colored insulation around it. I removed the terminal and wire from that slot and installed a new terminal with 6 feet of wire spliced on.
I then routed the new antenna wire along the door sill and to the rear seat area. Its now a 6 foot antenna instead of the small 2 foot one. I then started walking away and arming and un-arming the car. i got to the end of my court (roughly 50 feet) and it was still arming and un-arming even if i held the remote low and not up in the air. Id have to say this was a HUGE improvement and i am much happier not having to walk down stairs to arm the car.

I was 4 hours into a 6 hour trip (on the way home) and my air stopped working! when i press the AC button, it lights up on settings 1,2, and 3 but NOTHING blows from the vents (whether the AC button is pressed or not, nothing comes out!) however... when I turn it to "4," air blows full blast but the AC light turns off and only blows warm air.
thinking I need to check my compressor!
Golf IV / Jetta IV :: Overheating - Fan Motors Work But Not Cycling
I have been having an overheating issue with my 2001 1.8 turbo Golf GTI MK4. What I have replaced and checked:
-Supposed new water pump (dealer said they changed it when they did timing belt) (to be even more clear i pulled the top line off the coolant reservoir and there was a constant flow of coolant from the line meaning the pump is indeed working.)
-Thermostat (I personally changed it, 190* thermostat, aftermarket brand)
-Green top coolant temperature sensor (I personally changed it, its the one on the flange at the head, from the dealer)
-Cooling fan Thermo switch (I personally changed it, its the one located on the driver side on the radiator itself from the dealer)
-Checked fan motor speeds and operation. (I tested the cooling fan thermo switch and both fans came on at low speed, as well as both fans came on at high speed, which according to this test states the thermo switch is bad, but i already replaced it.)
I used the operation : [URL] .....
What my car does:
-Car starts to warm up and reaches 190* and fans start to cycle
-Both top and lower radiator fans become hot
-Car starts to get hot (indicator starts to go to the first line after the 190 line)
-Fans stop coming on
At this point i do one of two things to resolve the issue:
-start to drive (thus getting air through the radiator, and it cools the coolant and the engine.)
-turn off the car
What the problem is:
The fans wont turn on, on their own past a certain temperature, but sometimes when i turn the car off the fans will then kick on. (At idle, with the car on, they wont turn on again past, what seems, a certain temperature.)

View 2 RepliesGolf IV / Jetta IV :: Trunk Latch Won't Open / Key Does Not Work At All?
My latch wont open at all! When i first bought the car the trunk would open but Im not sure what had happened to it. The key doesn't work at all but every time I press the button on my key too open it or from the button on the floor it makes the noise that it unlocked but its still shut??!!?! Maybe I thought it was the fuse but I had changed fuse 15 still nothing any body experienced this before seems too be a common problem. Should I just go through the front and take the panels off for the hatch and diagnose whats wrong with it?
View 1 RepliesGolf IV / Jetta IV :: Replaced Evap Box, Heater Doesn't Work
I just replaced my evap box along with most everything connected to it (had some bad servos and replaced other stuff for good measure). AC works great now, but the heater still doesn't work. I've had this car 4 years and the heater has never worked. When I took the box apart, the doors were naked (no foam). Heater core looked ok, but thought it would be stupid not to replace it while I was there.
So, I was hoping this may cure my heater issue, but was really only looking to get the AC going. So, the car had been running for 30-45 minutes and while the heater was on, I went to check the heater core hoses, the pass side hose was hot, the driver's side wasn't. Driver's side goes to axillary pump and bottom of coolant reservoir. Not too long ago, I replaced the mechanical pump and t-stat along with other stuff (crack pipe, etc.). Thought I'd get everything while I had the system drained. Didn't work then, either.

Is the Horn and the Alarm beep the same unit? Maybe a fuse?
Golf IV / Jetta IV :: Inside Trunk Light Won't Work Even After Replacement?
I just noticed the trunk (inside) light was out. So I replaced it and it still doesn't work. I put a 'test light' on the pig tail and one side lights up so I guess there is power there. Once the' light holder' and lamp is in there it still doesn't work. Also when I put the 'test lamp' on one side of the metal holder the 'test light' lights up.
When I put it on the other side it makes the bulb almost glow like half voltage. What it could be? What is that resistor there for ?
