Golf IV / Jetta IV :: 2000 AC Not Blowing Cold
I have a 2000 Jetta that doesn't blow cold AC. Here are the details:
- When the AC is turned on, air does blow through the vents. Each setting (1-4) does blow harder than the previous.
- Both front fans spin and are working
- The AC compressor clutch never engages
- All fuses (two inside the car and the one above the battery) have been replaced and test good.
- When the AC is on full blast, the voltage coming from the AC compressor wire shows ~9.3V for about 5 seconds, then jumps up to about ~11V for less than a second, this repeats over and over and the clutch never engages.
What the next logical troubleshooting step would be? I've read about this possibly being the fan control module (maybe) and also read about testing the AC compressor using an external 12V power supply, but am not sure where to go from here.
Golf IV / Jetta IV :: Air Condition Is Not Blowing Cold
I have a mk4 gli and the a/c is not blowing cold, or remotely cool. When I turn on the a/c the engine drops rpm's like it is engaging, or whatever, but doesn't get cold. I checked under the hook and it sounds like something is trying to come on every 10 seconds or so...it's like the engine jumps or something. The fan on the passenger side is coming on if that means anything but the driver side doesn't when a/c is turned on.

'01 Jetta IV GLS AC not blowing cold air:
1. Blower works on all 1,2,3,4 settings
2. Cabin Air Filter Clean
3. When AC button pressed, I see the Compressor turns and noted the clutch also engaged.
4. AC Fan near Radiator comes on
5. Blend Door seems to be working fine - fixed the problem of spitting foam without opening up the heater box.
6. Since the above electrical parts seem to be working, I suppose it could not be a relay issue.
Golf IV / Jetta IV :: 2002 - AC Not Blowing Cold Air
I am trying to narrow down what could be the issue to my 2002 vw Jetta VR6 air conditioning. It is blowing air but the air is not cold. If I need to add refrigerant, where I can find the low pressure valve so I can do this on my own with one of those store bought cans.

No AC... Its not the fuse box on top of the battery, I recently already changed that. The air coming out is not cold at all, so I checked the pressure, and it was even higher then it was supposed to. After letting some pressure out, still no cold air. What could the issue be? Should I maybe bleed the system?
Also, its a 2001 GLX so I have climatronic....
Golf IV / Jetta IV :: 2001 - Compressor Turns On But AC Not Blowing Cold
My ac stopped blowing cold. The compressor turns on when I turn the ac on. When I pressure tested the low line port, it showed it was too high to add any recharge. 2001 jetta wolfsburg 1.8t....
View 2 RepliesGolf IV / Jetta IV :: 2002 - AC Quit Blowing Cold / Compressor Need To Be Charged?
The AC on my car (2002 Jetta 1.8t) quit blowing cold. Did some troubleshooting and...
1. Checked Freon- level was ok
2. Noticed cooling fans were not coming on with AC button pressed and ignition on. Fans also not coming on when car up to temperature, but gauge never went above normal. Seems strange considering I live in Houston and it was 95+ out.
3. tested fans with direct power and both high and low are fine.
4. jumped terminals 1,2 and 2,3 on plug for cooling fan switch and fans turn on high and low...so thought must be bad cooling fan switch.
5. Replaced cooling fan switch and still no fans or ac when AC button is pressed and ignition on.
6. replaced Fan control module. Still no fans.
7. Checked Freon once more...and although it was in the ok range decided to add a little more. (was in the middle of ok range, and a cheap gauge)
8. Compressor kicks on, along with cooling fan. End up using the 1 can I had and now have cold air and fans that come on when hitting the AC button with ignition set to on position.
I thought the mkiv cars would always turn on the fans when AC button is pressed with ignition on? Or does the compressor also need to be charged?
Golf IV / Jetta IV :: ESP Light On After Driving 10 Miles - AC Stopped Blowing Cold Air
So my alternator went bad last week so I replaced it. Tested it yesterday and it was charging fine and drove it to work. I got the esp light on after driving 10 miles everytime I start it. So I go start it and it turns over slow but starts. Before I got to a friends house I was getting on it from a stop pretty hard and noticed the ac stopped blowing cold air. I go to leave a few hours later and it barely turns over and died shortly after moving. Took a while to jump it and the battery light blinked the whole way home. THEN, I go inside and hear something about 5 minutes later and my stereo is on! Also ABS light is on. Could a dead battery do all this?
View 1 RepliesGolf IV R32 :: AC Turned On But No Cold Or Hot Air Blowing Out
Today I got in the car and turned on the ac, got no air blowing. Turned the ac off and the heat up, still nothing. I assume the blower is shot or maybe the fuse? I could hear the vents switching from top to bottom as I changed it but no air coming out. Where would the fuse be? What to check? Engine cooling fans replaced last year and working.
View 1 RepliesGolf/GTI VII :: 2006 - AC Just Stopped Blowing Cold
This is on a 06 GTI. Yesterday my AC just stopped blowing cold. I checked the fuses did not find any that were bad. Belts are new, compressor is spinning, not sure if the clutch is engaging, can't hear anything clicking etc. Upon further investigation it is doing some weird stuff. Fan speed works fine, blows air but no cold air however if I try and get hot air (the heater) there is no change in air temp. If I turn the "ECON" button on and off no change. If I turn on the front defrost then I get Hot air but that is the only way I can get any temp change hot or cold, nothing will make it blow cold just to clarify. Last odd thing is if I crank the heat up to max I get no airflow from anywhere!? What is going on?
View 2 RepliesGolf IV / Jetta IV :: A/C Is Blowing Hot Air Only
What are the normal things to look for to troubleshoot an A/C system? I do not have much experience with A/C's. I do not hear the compressor kick on, and it is blowing hot air. I know the fans should be on but both of them at the same time as soon as I turn the A/C on? I was thinking it's not the freon because it will lose its cooling over time not all of a sudden not work right?

I have a MKIV R32 and the other day I was driving with the A/C on, blowing cold air when randomly the air turned hot and hasn't blown cold yet. I took a look at the refrigerant levels today and they show a full charge along with the low-side refrigerant tube to the compressor getting cold but no still no luck.
The compressor is on so I don't think that's at fault, what else could there be? Something electrical maybe?

View 1 RepliesGolf IV R32 :: AC Stopped Blowing Cold - Driver Side Fan Wasn't Turning On
Well my a/c stopped blowing cold last week so I took it to an a/c shop and they said it was really low on freon. The guy recharged it and we noticed the driver side fan wasn't turning on. Said that it was causing to much pressure and it was blessing it off causing the loss of freon. So I came home and put it on the lift to check out the fans. I unplugged the fans from the bottom side below the fcm and the pass side fan comes on with a 12v source but when I put power to the other plug (drivers side fan) there's nothing across the high or low side. Guessing the fan is toast right? Just making sure before I order a new fan. What's all involved in replacing the fan? Also I've read the vw fans have a resistor that are known for burning out. Should I go with oem or a different brand from ecs?
View 5 RepliesGolf IV / Jetta IV :: Brake Lights Are Out - Fuse Keeps Blowing
First of all, its not a faulty brake light switch. I just found out that my rear brake lights have been out. I went to check the fuse and it was blown. I've replaced it but the second i touch the brake pedal, it pops again. Things I've tried...
I checked the wiring for any exposed wiring and i didn't find anything.
I disconnected the entire light assembly from the connectors on both sides and the fuse still blew.
I'm suspecting a bad ground, (as there was a point when the lights would work, even when i touched the pedal, but as soon as i pop the trunk open, the fuse would blow.
Where the lights are grounded? Is there anything else i should check?

Golf IV / Jetta IV :: A/C Malfunction - Air Stopped Blowing Out Of Vents
This morning my AC was working just fine, air blew cold and nothing seemed wrong. But then tonight when I went out it was cold outside so I decided to turn the heat on.. That's when a problem happened. Tried turning the AC on but no air came out the vents at all. Tried all the air settings, nothing at all, even when it's on "4". The only thing that seems to work is the re-cycilation button, it lights up and I can hear it working. So to sum it up, no air coming out the vents and the AC light won't turn on when I push it in.

View 7 RepliesGolf IV / Jetta IV :: Car Blowing Big Puff Of Smoke On Acceleration From A Stop
Well its a 1.8t pretty much stock except the previous owner added a turbo-back exhaust and has an apr tune running the 91/93 octane tune and they also deleted the stock airbox.
After the car warms up sometimes I'll get a pretty big puff of smoke on acceleration from a stop. sort of bluish in color and it happens randomly, not every time. I usually have to add oil about every week. I have taken it to a mechanic but told me it wasnt the turbo ( cause thats what i thought at first) and that it might be valve seals instead. I scanned for codes since CEL went on and i got a p0136 o2 sensor code and p0411.
Golf IV / Jetta IV :: 2003 GTI 1.8T - Oil On Top Of Turbo / Blue Smoke Blowing
My turbo started to have oil on the top of it. I don't know where it's coming from at all, it started to blow blue smoke but not all the time. You can also smell the oil burning off.. someone said maybe the pcv system but not sure. Still new to the vw world only owned the car for about 4 months. Trying to add pics but it's not working.. Will keep trying
