Golf IV / Jetta IV :: A/C Malfunction - Air Stopped Blowing Out Of Vents
Sep 15, 2012
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.

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....

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 2003 Passat 4Motion wagon with the 2.8 VR6 motor. I am currently having an issue with the air conditioning / climatronic unit. In the summer when the A/C is on, if the car is stopped hot air blows out of the vents. As soon as I start moving the air is ice cold. I have checked the compressor, had it recharged and everything on that end looks good.

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.

Yesterday I was driving with the AC on. I had it on the setting that blows out of all 4 dash vents (left, right, and two middle). I switched it to the option that should blow from the 4 dash vents and the vents in the floor/bottom. All of a sudden the two middle vents in the dash stopped blowing.
I have played with the settings - on, off, all the way hot, all the way cold - nothing from the two mid vents. The left and right vent blow with no problem. There is also cold air coming from the vent near the windshield - just the two middle dash vents are not functioning.
I found one thread that mentioned the problem may be with the "levers" or "actuators" that I have pictured here. I just replaced the 12v battery.

My car: 2008 Prius (base)
Here is the problem: All of a sudden the two middle vents in the dash stopped blowing. I have played with the settings - on, off, all the way hot, all the way cold - nothing from the two mid vents. The left and right vent blow with no problem. There is also cold air coming from the vent near the windshield - just the two middle dash vents are not functioning.
What I have done so far: I had it looked at by a mechanic who I trust. He said there is a small motor (he called it a servo motor) that controls that middle vents (open/close). He said that had gone bad. He manipulated it so that the air blows out of the vents now and said not to change any settings until I am ready to replace the part.

Is it true that on auto setting there is no air blowing out of the center vents? It happened to me this morning with my 2016 GTI.

I did a 9 hour drive last week and partway thru the trip the AC stops blowing out of the vents. No combination of punching buttons on the AC system solved the problem, although manually increasing the fan speed caused something behind the glove box to make a LOUD sound of rushing air (still nothing out of vents though). Finally I turned off the system completely for over an hour and then it magically started working again. I assume something in the system froze and had to thaw out. The exterior temp was low (mid-60s) but it was raining and the AC was keeping the windows un-fogged.

I've got a 2010 Jetta TDI Sportwagen and the blower fan stopped working (again).
About 3 months ago it stopped working on the 1-3 setting and 4 worked fine. So I searched these forums and found the resistor pack was blown. Replaced it with the ~$30 official VW part and it worked fine until last week.
Now all settings are not working. I ohm'd out the resistor pack and they appear to be fine. I put a current limited 12v supply on the fan and it spun up without a problem. I checked the voltage coming from the car to the fan connector and it was at 0v.
From reading the forums this tends to point to a faulty switch. If it is a fault switch then why does the AC light turn on when I switch from 0 to 1?

I've recently purchased a 2007 Prius and I just noticed few days go that A/C blows warm air (weather was fair when I bought it and I can't remember if it really worked or not then) and middle vents do not blow any air. I'm not sure if two problems are connected but I do want to get both fixed without spending $$$ at the dealership. Where can I start?

My R stopped blowing any air. I can just barely feel warmth coming from the vents, but blower is not working... I looked for some threads on this but nothing.

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?

Of the 4 vents that blow into the passenger's face in my jetta, only 1 really works. All other vents seem to work well (i.e., windshield defrost, footwell etc) but the ones that blow the heat/AC in your face seem to be affected. the one working vent is the driver's side of the 2 central vents (the ones above the stereo) neither of the 2 for the passenger work, and the one by the Driver's door works a bit.
I've tried opening them with the dial on the dash and closing, but that seems to have little effect. Are there dampers or something that can be adjusted on the inside of the vents?
I've spent some time searching on this one and I mostly found how to replace the heater-core and the blower itself. The blower works as does A/C, that one vent is ice-cold, but the other 3 don't really do anything.

Been the proud owner of a '04 Golf for a few years but it hasn't been without its share of hiccups. I recently had my battery die on me. Got the car looked at and apparently the alternator was the culprit, ie, it wasn't functioning and re-charging the battery. Swapped out the OEM for a rebuilt Bosch 120A (my car is a 2.0GL, so it's supposed to be 90a default, but I looked online and saw that I could use the 120). Even put in a new battery as the old one was past its prime. Now the new alternator (which was not fun to install) isn't working either. I had a different mechanic look at it and they said that while the auto shop gave me the right part number, that apparently VWs are hinky with aftermarket parts and I'd have to take it to a VW dealer for a diagnostic? Makes no sense as I've seen tons of people online who've used aftermarket alternators with no problem.
So now the car essentially is dead in the water. Battery light comes on when the car is started and I'm not tempted to not drive the car anywhere out of fear that the new battery will die in mid-traffic. I've checked the grounds, pulley, etc, everything looks fine and connected proper. What could be going on?

This is my first VW. My first European car at all. I've been having what I think are battery issues, but they're weird. Every... I'd say 3rd or 4th start, I just get the clickclickclickclickclick thing. Then I jump it and it starts fine. When I don't have to jump it, it's been starting rough. When I jump it is the only time it starts smoothly. To me that screams battery.
The other day, I went to start it and it wouldn't start. But I had nothing to do that day so I went back inside and did whatever. Went out about 5 hours later, and it started just fine.

I go my R32 calipers powder coated, I rebuilt the err m and got 20th rears while I was at it.
I did make a noob mistake and pressed the brake pedal to try to manually bleed my rear brakes (used a vacuum pump prior) then I remembered my front calipers were off.I might have pressed it 3-4 times.I re-bled all 4 corners, once all 4 calipers were on, and did so until I was sure there was no air.I read in a few places that our rear calipers bleed because the bleeder screw isnt at the high point, which makes sense. So Im wondering if this is what I'm experiencing or is there something, via VAGCOM, I have over looked?

So i just had my R32 at the stealership to get my AC recharged. Ever since ive noticed that my AC doesn't always blow cold. It will vary from cold to warm and back to cold then warm. Im not even sure what to start looking for as the issue

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?

I have a 2003 Jetta GLI. When i turn my a/c on some of the vents blow harder and colder than the others. Why that would be?

I have an 01 GTI GLX with climatronic, and I've noticed this hot plastic or hot wire smell in the vents. Yes the fan wire gets hot when the car is hot and AC is on. But I don't think that's it. I've torn the passenger side apart, took the blower motor out, not it. The vent / recirculate motor is external to the vents, the only other place is behind the radio for the other one. What else is internal, if anything, that could be causing this smell? I'm concerned that something will melt or burn up.
I've been wondering if the ecm in the cowl would be getting hot but I can't smell anything with the plastics on. I would say it does seem to occur after driving for about ten minutes in town. But it also seems like it's there when I first start it up also.
