Passat (B6) :: Fans Blowing On Super High After Car Is Shut Off
Jun 11, 2009
June, 95 degrees. Over the past couple of days after I shut off the car, both my fans kick on and I mean kick on. They sound like a helicopter is hovering inside my hood. They blow on "super high" for about 3-4 minutes and shuts off by itself. If I start the engine, the fans will quiet down drastically, basically to a point that you can't hear it over the engine, but as soon as I kill the motor they kick back on high. My B6 has just under 52k miles and I'm driving the car for 3 miles (5 minutes) when this occurs.

I have an 06 Passat 2.0T, and last night whenever I shut off the car, the cooling fan is constantly running. I had to unplug the battery so it wouldn't drain it, and about 5 hours later, I hooked it up and it stays off. I also noticed when turning on the air conditioning, the smaller fan doesnt kick on. I'm lost and don't know where to start. Could it be a thermal switch or the whole fan assembly

My gf's 2005 passat is not blowing any hot air out when the heater is set on high. yes, she did turn it on and yes she does know how to work the climatronic. I've noticed over the last couple of months that the passat was not blowing really hot air out like it use 2.
now it's just blowing cold air.
what would cause this?
I am assuming and HOPING that its just an air bubble in the coolant system.
IF not maybe the heater core is going bad or clogged? is there a way to fix this?

My cousin was driving his car last weekend and the car shut off on him, after we towed it home i hooked it up and got the following codes:
2 Faults Found:
012555 - Low Pressure Fuel regulation: Fuel Pressure Outside Specification
P310B - 001 - Upper Limit Exceeded - MIL ON
Freeze Frame:
Fault Status: 11100001
Fault Priority: 2
Fault Frequency: 2
004767 - Low-Pressure Fuel Pressure Regulation: Pressure too High
P129F - 001 - Upper Limit Exceeded - Intermittent
Freeze Frame:
Fault Status: 00100001
Fault Priority: 2
I cleared the MIL and its off but its still throwing the second code.. What would cause this? failing fuel pump?

I went out to my car this morning and the fans were both running full speed. That's before I even got to it then they carried on doing so when I started the car and still ran after I shut it off. I have stopped them by pulling the 30A battery top fuse for them but what has caused it and how I can fix it? Preferably not too expensively as I am moving house next month typically.
The car is a 2003 1.8t GTI with climatronics ....

Well I noticed the fans are running at shutdown, then next day check engine light plus the jack light which I was able to turn off. I have had the same symptoms several months ago and they went away. Now its back.

I bought a 2002 gti mk4 with about 127000 miles on it .I did not know the turbo fans were blown out , they were sitting in my down pipe next to my catalytic converter . So I replaced the turbo myself , and 2 hours later the fans fell out of the new turbo , what might be the problem ? why it keeps blowing.

Believe an engine temperature sensor is bad. I took it in to get a code read, and they said it could be either temp sensor or fan switch, but didn't know which one without newer software.
Codes are
19537 - Engine Temperate too Low
P3081 - 008 - Implausible Signal
I've checked the fuse legend to see if there is a fuse I can pull, but none of them marked fan seem to kill it after the car is off, so that I can save some battery power.
I believe that I have narrowed it down to the engine coolant temperature sensor. What is the level of job this is to replace? From a parts location manual, it looks like it is in the Thermostat housing, but I'm not sure where that is.

I have a 2006 F-250 Super Duty (6 liter diesel). The high beams stay on unless I pull the fuse (fuse 30). It doesn't matter what position the headlight switch is in. It is like the high beam flash on the multi-function switch is stuck. It feels fine, but high beams stay on regardless of position, even with the truck off. The low beams (if in low beam when the truck is shut off) do go out as do the running lights after 15 or so seconds (normal) it's just the high beams. Also the high beam indicator light is on all the time (until I pull the fuse) and the fog lights will not come on until I pull the fuse. Should I replace the multifunction switch or look elsewhere?

X2 nights ago at 11:45pm I was driving home from a friends house with my gf and were going about 65 on the highway and it's lightly raining, then all of a sudden my headlights, windsheld wipers, turnsignals, my ac/fans all just shut off so I had to pull over right away. After sitting there for about 15 mintues I figure out my high beams still work but only if I hold them on(clicking it on doesn't work. So I drive home and the next day check all the fuses in the drivers door and they r all fine. Everything else works in the car but the stuff stated above. My car was reposesd about a year ago when I lost my job and they put this thing I have to enter a code every month, it messed my windsheld wipers and turn signals up before but not anything else! But it still works and the other stuff doesn't, and behind the dash it sounded like crackling and smelt like burning electric right before it shut off.

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.

Have a 2002 SC lariat with climate control. A few weeks ago, the system stopped blowing air. It seems the brains still work for temp control as I can adjust the temp and the natural flow air through the system will change temp.
I heard a sputtering noise from the fans a few weeks ago at about the time it quit. Is this because the servo motors for the fans quit or if it would be something from the controls?

After about 10-15 minutes, following a cold start, this 2007 BMW X3 3.0 six does the following:
1) automatic cabin fan behaves erratically, jumping back and forth between low and high speeds;
2) cabin air does not heat;
3) electric radiator fans run on high;
4) coolant temp rises to normal, but then will suddenly jump up to full hot.
At this point, driver of course pulls over and shuts off engine. The amazing part is this: the engine can be re-started IMMEDIATELY and all of the above problems vanish instantly. Radiator fans shut off, temp returns to normal, cabin fan works normally, and cabin heat comes on. I'm thinking sticking thermostat, but why does shutting off the car momentarily fix it? Change of water pressure when coolant pump stops running?

I've figured out why my car has been overheating lately, the fans aren't running at all! How do I get the front end off and check things out, is there a fuse diagram for the B6...

I have a 99 B5 and the lights for the Heater Temp Knob, the AC/ heater Fan Knob and the blower direction knob are all out. The fuses are OK. I have checked that.

First summer with 2014 Passat. We have been getting close to 90 degree days this early in Summer and I have noticed a sensation that I have not had with almost the first year of ownership.
The last couple of days in stop and go traffic I have noticed that when the Radiator Fans edge up to the fastest cooling speed I can feel a vibration in the steering wheel. It is a strong vibration feeling. I had a friend turn off the car while the fans were going full speed. The largest fan on the drivers side seems to wobble as it cost down from the high speed. I am wondering if these fans can be balanced with counter weights.

My car just started over heating and I checked the fans and they are not running. I'm new to the VW family and although I love the way this car drives I've been baptized with quite a few problems.
