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 RepliesTurn the interior air fan On, select air for Windshield, AC Button turns On. I turn off AC (amber light turns off on AC button), but i still get ice Cold air that is blowing on to the windshield.
I this normal? Never had this issue with other car makes.
Just want to know before i take a trip to the dealer. Its a new car with 5k miles on it. Its been doing this since day one.
I also cant select recirculated air for windshield.
On occasion the heat on my mk6 golf will start to blow cold when turned to the max click. Turning it back one click will cause it to start to blow hot again.
Friend at the dealer said he thought there was a software update for the hvac controls ....
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.
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.
View 4 Replies'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.
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 Replies 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.
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 RepliesNo 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....
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 RepliesWell 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 RepliesThe 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?
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 RepliesI have 08 460 I got in today and turn on the air and it blows hot. Made sure the AC button was in and it was. So I left car running had someone push the AC button and the compressor doesn't turn!
View 6 RepliesMy 98 ford ranger only blows hot air .when i rotate temperature control knob there is a sound of a creaking door behind dash but only hot air blows even if i turn on ac.
View 2 RepliesLong story short, my Ac went out yesterday morning. There is absolutely NO AIR blowing out at all, not hot or cold... Its been 2 days and its about 120* where I live. I have a 2007 bought new, 150k miles on it and have NEVER had any problems with anything...
View 9 RepliesNew owner for the passat 2003 gls passat 1.8T. I turned on the AC and its not blowing cool air. Looking for DIY to fix my AC problem.
View 3 RepliesWent to turn car off and vents kept blowing air even after car turned off and key out. Replaced the blower module and that didn't work. Am I doing something wrong? Kinda cold out, would like some heat...
View 10 RepliesI have a 1996 geo metro that I have been working on for the last couple days. The problem that I have been running into is the ignition fuse keeps blowing the instant that the key is turned.
This kills the power to the fuel pump as well as the power to the ECM. (killing all the idiot lights). The engine still cranks over and all the accessories still work.
I have tried disconnecting the fuel pump wires as well as the ECM and the ignition module to try and narrow down the problem but the fuse still blows about 2 seconds after I turn the key.
I have a 2007 Prius. I turned on the AC for the first time this spring last week and the air blowing out of the vent was ambient temperature. When I looked through the sight glass with the AC running, it looks like there's fluid in there, but it's not moving anywhere and the evaporator pipe did not feel cool. I also replaced the 12 V battery a few months ago, with an optima yellow top battery.
What's wrong with the AC? Will a recharge do it fix this, or did I mess something up with the battery. There were a lot of warnings about "resetting" the system after you have the 12V out, but I didn't seem to have any problems that were described as symptomatic of needing a reset.
