Passat (B5) :: HVAC Control Died All Of Sudden
Jun 6, 2006
Yesterday, my wife said she tried to turn the fan control knob from 2 to 3, but there was some resistance. She turned it off, and when she tried to turn it back on, nothing happened. The fan control knob turns as it should, but no fan is blowing, and therefore, no AC. Also, we noticed after dark that the lights inside the HVAC control unit had also died. I was thinking fuse, but checked all fuses related to HVAC and dash lighting and they were all OK.

Car went in to the dealer to have headlamp replaced. Tonight I noticed that the HVAC Control Illumination wasn't working. Could they have possibly shorted something out? Tomorrow I'll check fuse box.

My 2003 Jeep Cherokee totally died all of a sudden. No lights, no locks, nothing. I am skeptical that its the battery because of how sudden this happened.

My daughters boyfriend was driving his 98 Expedition this evening and it died. From what he is telling me, he said it just all of a sudden lost power. As he was coasting to the side of the road, he said the RPMs where fluctuating then died. It cranks but won't start. No "theft" light flashing. All fuses under the hood are good. Turning the key, can not hear the fuel pump pressurizing.
No pressure at the Schroeder valve on the fuel line. While trouble shooting, found where someone had done a hack job of splicing the ground battery cable, wire was just folded over to hold together. As we were towing it home, they said there was a beeping coming from behind the glove box, which is where the PCM is I think. Kinda stuck on whether it could be PCM or fuel pump.

I was driving my 85 2.3 liter down the road and it died all of a sudden like and wont start back up. I took out a plug to check for spark and had someone turn it over and I touched it to the big metal part the grill connects to at the top but I got nothing. It IS getting gas. The spark plug was white as if it was really hot and rough-looking for its relative newness. I bought a new distributor cap because it was corroded, but it didnt work. They tested the ignition module at the store and its good, so I am thinking distributor?? Also, could compression issues keep it from sparking? I am a little worried it got over-heated somehow, but don't know....

So last night I was on a 55 MPH road that has a gradual right curve, that ends up at a stop sign in a T intersection of a major highway. I was in the process of slowing down when the engine all of a sudden died. Then the brakes and steering went as stiff as can be. I made the curve and was able to stop at a semi decent location. After checking my shorts. I tried to restart it and it would only run a few seconds with rpm's jumping all over the place. the check oil light would flash and then the engine would die.
I was able to get it to move like 20 feet to the side of the road. The major problem is the bumper to bumper warranty was up 6 months ago. So I just had it towed home. Now it's time to figure out what exactly is wrong with it. I tried to borrow a code reader from the local parts store. But none of the ones by me will lend them out anymore. This is also my only vehicle for the time being. I have had the vehicle since feb of 2009. It is a 4.6L 3v engine and only has 27000 miles on it. I have read a few things online about them stalling.

I was just wondering is the climate control self contained so it can be directly swapped for manual HVAC controls? I have a XLT and would like to upgrade the HVAC and radio system if possible if they are direct swaps.

I have a 1989 F250 4x4 with a 1990 460 EFI under the hood. As I was driving All of the sudden as i finished turning a corner the truck died. No Spudder like it ran out of fuel but more like someone had turned the key off.
I tried to restart it but i kept it short i was near other houses and it was 3am in the morning. On my way to work, I popped the hood, thinking okay we had a bad rain storm. Moisture in the Cap and rotor. Well went to pop it off Distributor is lose, oh joy. But the cap was dry but i did take out the rotor to clean the tip off and the cap too.. Still nothing when I tried to start it again.
I am getting ready to check for spark from the coil *hoping it just a lose coil wire*.. But would the Computer taking a vacation for life cause this.?

I just picked up this truck and have found my first undisclosed problem. The A/C only works on MAX. If you turn to any other setting, regardless of selected temp, the air blows hot. And I mean full hot! I was thinking the control panel assembly is bad?

2000 jetta 1.8t ... Yesterday driving home from work (1.5 hr drive and it was 25+ degrees) my car died on the highway just before I made it home. Just lost power all of a sudden with no warning signs before and no overheating. No lights came on I just felt sudden loss of power and pulled over and turned the ignition off and it wouldn't start again. Just makes a high pitched whining noise and won't crank over. I just found out the other day that both O2 sensors need replacing but I can't see that being the reason.

Earlier this evening on the highway while in cruise control I had a strange issue. Going up a slight incline all of the sudden I lost power, my ESP and EPC lights came on, and the engine was running very strange.
It wasn't stuttering but was louder and vibrating a whole lot more than normal. I pulled over and shut the car off for a couple mins, started it up, everything was normal and continued. About an hour later the same thing happened and when I started up the car again the check engine light was on.
I had my room mate scan it when I got back and it came up with ECM and PCM processor errors. Not sure what kind of problems this would be. All the searches on cruise control didn't turn up anything like this. What the problem would be? The cars a turbo'd r32.

Ok I have an early 2004 F250. Recently changed out the #8 injector and then had to replace the ICP Sensor. Was running great then while driving down the road just died all of a sudden. Would start right back up with no issues. Continue driving and I am getting intermittent power loss. Also noticed that when it would lose power suddenly the glow plug light would come on.
Codes are P0102, P0113, P0272, and P1000.
P0102 Mass or Volume flow circuit low input
P0113 Intake Temp circuit High input
These are just soft codes not setting a light off. MAF is plugged in and I will check wiring here later after work but could this be causing my intermittent issues?

2000 GM Buick Regal. Parked the car overnight and in the morning could not start the car. Mechanic said the BMC memory was completely lost. I would like to avoid this happening again. Car battery is 6 months old and strong. What would cause a total memory loss in a BCM when parked in a lot overnight.

My 2003 Passat has a musty smell coming from the HVAC system that just won't go away. Have resealed pollen filter and had airsept treatment (this worked for a while, but now the smell is worse than ever). Two dealers have tried (and failed) to fix this. It's so bad I can't take passengers in the car.

Have a pulsing noise when the HVAC is turned on (see other post about HVAC pulsing noise etc). I've traced the sound to behind the glove box, I suspect near where the cabin air filter is. I believe the blower motor is back there too? How to remove glove box to get to blower assembly...

My 08 B6 wagon has a very foul odor emanating from the HVAC system. It started after my wife washed the windshield with vinegar to get rid of some scaling from the bizarre water we have here. She thought the smell was from some of the vinegar running off the windshield. Well, that was several months ago and the smell is no better. Just recently, the temps have been down enough to turn off the AC switch and the smell is even worse.

2014 TDI Passat with 66k miles. No unusual problems until this point. Three days ago I began to notice a strong ammonia odor coming through the ac vents. Its become significantly worse over the last 24 hours. The vaporized ammonia is sufficiently concentrated to cause eye and nasal irritation. It occurs rapidly, within 30 seconds of turning on the recirc mode. Turning off the recirc mode can clear the cabin quite fast as well. There is no odor or leak perceptible in the engine compartment, under the car, or in the trunk space.
No check engine warning or alarm that there is a problem with the DEF system. DEF fluid container was last topped off about 5k miles ago. Clearly, this is a significant failure of the emission system. I've done a cursory search but have not seen this exact problem written up before. Wondering why a car would be designed with the HVAC close to the to the exhaust/emissions system that it could capture gasses intended for the exhaust system? Its not so much the ammonia I/m worried about as the odorless and toxic Nox gasses the emission system should be reducing. getting dropped off at the dealer tomorrow.

I know this has been covered many times before but I know how to remedy the problem. My question is that I have an 09 which is still under warranty, is replacing the cabin filter/charcoal filter due to bacterial odor covered under my bumper to bumper warranty? I found some posts where people said it was but I want to double check before i waste time that I don't have with the dealer since I've been really busy with school.

Had just got done filling up with diesel, drove 1/4 mile and truck just died. Tried to start it and nothing. No power to edge tuner either. Fuse #22 20a under steering column blown (engine control). Replaced and keeps blowing. not sure what is causing it. Just another wrench to throw in my wedding week!

My a/c blows nice cold air, then all of a sudden click it stops as if the cabin reached the ideal temperature, but the cabin is warming up. I dial down to LO but the A/C doesn't start blowing cold air. I shut off the car, restart and it starts blowing cold again. I even got it to start blowing cold air again when I accelerated, speed off.

I have an 08 2.0T and it just suddenly had a huge drop in gas mileage. I recently had new tires put on and an oil change (about 35k miles). getting closer to 40k miles now and wondering what could be causing this. Usually I get about 30-33 mpg easy on the highway. Now I'm getting 24-26 mpg. Already checked the tire pressures. they're to spec. no gas leaks from what i can see.
