Let the car run for roughly 15-20 min still not at full operating temp 90 celuis, and when it is at 90 only blows warm air not hot hot air advice> water pump and timing belt have been done in nov as well as coolant flush.
View 5 RepliesMy car recently started making strange noises sometimes. Sometimes I hear a whirling sounds coming from the bottom half of the block which I'd hope it isn't the water pump. Also when i start my car and it cranks over, I hear what sounds like a blow off sounds but its not from my diverter valve.
View 5 RepliesI have an 01 Jetta 1.8t wolfsburg eddition and the AC won't blow cold air. The AC Clutch does engage when I press the AC button on the control unit The refrigerant pressure is good The fan blows, but its hot air. the condenser is working because the pipe is cold when the ac is running I am curious if any of you know what other possible problems could be causing this. It is currently 100 degrees with 100% humidity
View 11 RepliesOf 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.
Mk4 problem: my interior fan in my Jetta doesn't work on any of the levels, the ac button doesn't work either, and nothing is lit up except the recirculating button.. Resistor?
View 3 RepliesI 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?
View 10 RepliesOk here is the issue, my girlfriend owns a MK4 '99 Jetta. Through the search I was able to figure out why she is having so many issues with her door locks and how they can be fixed on the cheap..thats awesome. But here is the problem. She was driving down the road the other day, A/C working...then suddenly it stopped blowing cold. Fan is still working, just blows hot air. She said it started blowing warm suddenly and hasnt been getting warmer through out the past days or anything.
With the hood popped and the a/c on, you can see that the compressor isnt engaging. The car makes a noise like its engaging the compressor, but nothing is happening that I can see visually. Seems as if the compressor is not getting the signal to engage. It sounds like its trying to make the compressor kick on about every 5 seconds or so. Basically that initial clicking sound that your hear RIGHT before the compressor comes on when its working normally.
We have checked the fuses and no luck with those, all look good. Seems like its an electrical issue to me. What this may be? Bad pressure switch? Low pressure in the system? I know the car has had the compressor replaced before...and the clutch seems to spin freely when the car is off.
Let's start from the beginning. 3 months ago, I replaced my oil pan, and since then I've noticed that white smoke would randomly blow out of my exhaust- A couple times when I really got on her, and a few times when sitting idling for 10-15 minutes.
Two days ago, I was driving and about to hop on the highway to make my 40 minute commute home, realized that my temp had gone up about an eighth over 190 (usually stone cold centered)... Watched it for another 2 minutes and the temp was 3/4 of the way to the red, so I pulled over and popped the hood.
The coolant reservoir was COMPLETELY empty, which didn't really make any sense- I had been running my AC all day because it was hot out, but I don't think I was idling with the AC on for too long.
I let her cool off, had a friend bring me some coolant (not much at all) and a TON of water. Filled her up and went home; temp was trying to climb but I wouldn't accelerate too much so she wouldn't go much higher than that eighth over the 190 mark.
Next morning, dropped her off at a mechanic's before work, asked for an oil change, inspection, and to check out this temp issue. These guys told me that they ran a compression test and everything was okay, no leaks or cracks in any hoses so it is a faulty turbo. They also stated that in idle, there seems to be intermittent white smoke out of the exhaust- coolant burning, obviously).
Drove it from them to a spot nearby to let her cool off because I wanted to see if there was more white smoke.. Driving TO the location, I blew A LOT of white smoke on acceleration, I had the heat blasting the entire time so the temp didn't really rise too much.
I'm hoping it's not the turbo, reading up on these issues in here it could be a number of things, but the ONLY reason why I don't want to spend a fortune on replacing the turbo right now is because one or two mechanics i spoke to today said it's not the turbo, but 3 others said it was...
I have no loss of power, no hesitation, and no abnormal sounds from the turbo. Actually, she sounds amazing. I don't however thing it's a head gasket because the dipstick and oil cap aren't milky.
My 2005 Jetta gli 220k miles just spurred going down the road now every time I accelerate and get into high Rpms the Ac vents start to blow harder and feels like loss of power. It's fines at idle and first gear but 2nd and up its does it I'm stumped....
View 2 RepliesThe A/C does not blow cold. The Compressor clutch does kick on and stay on The passenger side fan kicks on only (I think the driver side is toast but i need to test it to confirm) The system has 45psi on the low side
I did not check the high side as I don't have a gauge for it but will get one if I need to test that. So my thoughts are that my expansion valve is toast which is what expands the hot liquid and turns it to cool liquid so the A/C gets cold. I think this because it seems all of the other components work.
I recently put a cold air intake on my car and I could hear the dump when I let off of the gas. But I also put in a boost gauge but I think I had a leak in the hose going to the gauge. After I drove it for awhile the blow off valve started making a flutter noise when dumping. I fixed the leak in the hose but the flutter is still there. How do I fix the flutter? A new blow off valve? Mk4 Jetta 1.8.....
View 6 RepliesI'm at the end of my rope! My 2005 Ford Five Hundred Limited has a constant problem with the A/C system and overheating. In the last year I've replaced the compress, expansion valve, dryer FOUR times. They have replaced the condenser, blower motor, and added Freon, and checked for leaks. It will blow cold when running fast and then blow hot. They have replaced belts pulleys, They have replaced the thermostat, fans, coolant reservoir, hoses. and it still overheats. I've taken it to 4 difference mechanics including two dealerships. No one can seem to fix this problem.
View 9 RepliesI've only had the car about a month, and love everything about it. . . . but with the onset of cold mornings, I'm not very excited about the luke-warm air coming out of my heater.
It's reminding me of my old B5.5 Passat VR6 wagon and the annual heater-core flush that it required. Of course, the Passat was 13 years old and had 200k on it.
Today my a/c stopped working, it just blow normal temperature air not cooling, never had a bad experience with it before, I even use it not on the lowest set up, always on 19 Celsius. It was working fine when i arrived at work, 10 minutes later My boss told me to pick something up and when I turned the a/c on it Never worked.... Is this normal?
View 1 RepliesI got my APR ECU & APR Intake done at the same time about a month ago. After both the upgrades I hear the turbo winding and a slight blow off sound more between shifts. Is this due to intake or ecu tune? My brother drove my car yesterday and asked me however I told him I'm not sure...
View 1 RepliesA few months ago, when I used the AC, it would kick in cold for a minute, then blow hot air for three minutes or so... and repeat. I checked into it, and the only error I got was the N42 resistor short to ground code. Looked it up, and it's supposed to be located here:
(#1 in the pic).
Funny thing... Cars with Climatronic don't have that resistor in that location (or at all from the searching I've done... and my blower works fine on all speeds). A week later (after a cold front), the AC worked flawlessly... Through SOWO. Wasn't until earlier last week that I noticed it crapped the bed again. The compressor isn't even kicking on... I haven't had the chance to scan the car again, but I'm going out on a limb to say it's the same error, to a resistor that isn't on our cars...
The compressor seems to work perfectly when it does work... So I'm thinking something's not kicking it on like it should. I'll be checking all fuses/relays tomorrow in the daylight.
The climate control can be completely off (fan, everything)... and my vents will commonly continue to blow (room temp) air. Don't know if I'm missing something here. This is while in motion or stopped.
View 1 RepliesAir conditioner was acting weird. (It doesn't blow cold air when the car stops at the lights or in the parking lots. But it works great while driving). Then I went to dealer. And they scan my computer. And they said we need to change Aux Fan control unit and also one of the fan .I ordered OEM Aux Fan Control Unit . And I installed it. I connected Vagcom and cleared the Fault code but It still acts same. I checked the fans. They both works fine to me. They run 10 seconds and stops. So I didn't get this part. How the heck this AC works fine while I am driving but it doesn't work when I stop ?

View 3 RepliesI have a mk4 jetta vr6 200,000 miles with a bigger pcv and a cold air intake ( universal) and silicone vacuum hoses and secondary water pump delete and exhaust. (Just a little info) I seem to have a lot of blow by and its been eating 2qts or so of oil between oil changes. I am using 20w50 castrol gtx high mileage and a locus and is still eating it (2qts). I do drive it hard and race so I figured it would be fine the thicker oil plus arizona heat. I am thinking maybe more lucas additive about 40% of lucas and 60% 20w50. Just trying to keep it running support the worn seal and compression and horsepower and of course oil lose. It is such a pleasure to drive and race.
