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?

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?
Golf/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?

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 3 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 :: 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 :: A/C Won't Blowing Cold Air Even Gassed Up - Fix?
having the issue where there aircon refuses to work even if the system is gassed up and leak free, and the compressor seems to be functional but not powering up. Before spending loads of cash on controller units, swtiches etc, your problem might be a dodgy connector under the battery tray.
As I have bought another Golf that appeared to have this issue, I took some photos this evening while I fixed it, hopefully this will be of use to people?
To start with, I had a look at my old Golf, which I knew had already been repaired. under the battery tray I found the repair. I put new tape on as the old tape was showing its age, so it shows up quite nicely - it's the blue tape!:
and a bit of a close up:
So now I knew what I was looking for, I had a look at my new Golf:
Which, I cut out, soldered the ends together, heat-shrink wrapped, then covered with some more trusty blue tape and zip tied it all up to try to minimise further chafing (the blue tape on the left is another part of the loom that looked like it needed a bit of tidying up):
A drive around this evening shows the aircon is now blowing a lot colder than before (previously it was blowing hot air after 5 minutes). I'll be testing it properly on a hot day, but I'm 90% certain I've nailed it.
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.
View 2 RepliesGolf IV / Jetta IV :: 2004 - Overheating / Fans Stopped Working Correctly And Fuses Kept Blowing
I have a 2004 volkswagen jetta, and it has started overheating. At first my problem was the thermostat. After that was changed out the fans stopped working correctly. It kept blowing fuses in s180 slot.
I read somewhere in another post that this is due to the fact the resistor in the low speed fan go bad, and for your car's radiator fan to go from zero to high speed, causes the fuse to blow. Also I read that when the fans start up it draws the most current, and then after it's running the current is considerably less.
This is my solution, I went to napa, and got a circuit breaker for a car, and Yes, to my surprise they make them. I picked up several a 10amp, 15 amp, 20 amp, and a 30 amp. First, I tried the 30 amp circuit breaker and it didn't trip the circuit, but when I put a regular fuse in the slot, it did trip the circuit, when I did the fan test at the thermostat switch. Next, I put the 25 amp in there and neither did it trip the circuit. When I put the 10 amp in the s180 slot, it tripped the circuit, just as the regular 30 amp fuses do. So that confirmed that the amps that were being drawn from the fans were not enough to trip a 30 amp circuit breaker.
What I did next, is I took a 20 amp circuit breaker and put that in the s180 slot. Then I hooked up vag com on my laptop to check and see how it performed with the 20 amp circuit, and these are the results.
Car Temperature in celsius
at 111 degrees the gauge was moving past the halfway point
at 115 degrees the gauge was one notch past halfway going towards the red zone
at 120 degrees the gauge was two notches past halfway going towards the red zone
at 122 degrees the fans kicked on high speed for about 30 seconds, and knocked the
temperature down to 105 degrees.
In conclusion, if the high speed on the fans work, you don't have to take those out and go and buy an expensive new fan set. Just stick a 20 amp circuit breaker in the slot, and keep using the fans that you have.

Golf IV / Jetta IV :: 2001 - Compressor Turns On But AC Not Blowing Cold

View 1 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?

Issue I have with my 2012 Prius I bought about 9 months ago. The air stopped blowing completely. No hot air blowing, no cold air blowing. It is starting to get warm out now and need some AC. Is it the blower motor under the glove box that has gone out? Seems odd.
View 1 RepliesFord - Escape :: 2012 - AC Stopped Blowing Cold Air
Last summer, the A/C on our 2012 Ford Escape stopped blowing cold air. We took it to our mechanic (who I trust). They checked for leaks but found none. They did an evacuation and recharge of the system. Cold air started blowing again! Then 2-3 weeks later, my wife says she saw a puff of smoke come out of the vents (not sure if it was smoke or vapor or what). The A/C stopped blowing cold air shortly after that. We took it back to the mechanic. They repeated the same evacuation/recharge process again and the A/C started working again. 2-3 weeks later, we saw the same puff and then no cold air.
That happened last Fall, so we waited until this spring to try again. Just took it back to mechanic. They checked the levels and the pressure was good before they did anything else. No leaks. They did the evacuation/recharge and the air is now blowing cold again. But, I have no reason to think it will last.
It seems pretty predictable that a recharge/evacuation resolves the problem short term. Why it's not lasting? What, if anything, could I try to diagnose? Seems that my mechanic does not know what else to try.
Camry :: AC Stopped Blowing Cold Air And Indicator Led On Switch Blinking On And Off
There have been two occurrences where the air conditioning has stopped blowing cold air (blows warm) and the indicator led on the switch is blinking on and off. This has happened twice, about a month apart. The air is generally plenty cold. Does this means the air is going out on my 2002 camry ?

The A/c stopped blowing cold on my 06 Passat 2.0t. I checked the pressures on the low side of the system and it was 100 psi with a cold engine and 130 when hot. Obviously this is too much. It seems as if the compressor is always engaged even when the a/c is off (every part of the a/c pulley is always spinning the little nut sticking out of the center of the pulley spins as well not but im not sure if that's how it is when the compressor isn't engaged).
