how common a problem it seems to be that our fans just stop working. Replacing those later this week.
My question is concerning my AC not working. Is it possible that, since the two fans won't work at all, the AC system won't engage? Or do I have two completely unrelated problems?
New GTI. I can manually put all 4 windows down and open the sunroof then get them all to CLOSE by holding the lock slot on the door but I simply cannot get them all to open at once holding down the driver window switch. I'm doing exactly what the manual states to do. With ignition off. But with power either on or off this doesn't work for me.
View 8 RepliesSo I just got a 2002 1.8t, everything was fine until the fans and ac stopped working. After poking around the forums a bit I changed the following:
1. Fan Control Module. Result: nothing
2. Radiator Cooling Fan Switch Temperature Sensor. Result: nothing.
all fan components have the correct voltage going to them. Fuse 16 for the AC clutch is not blown and has power going to it. The AC compressor has power going to it. The fuses on the battery box have power going to them specifically S180.
My question is what am I missing? is it possible that the fans themselves could be bad? car is not overheating, the after run coolant pump kicks on. But the AC clutch is not spinning nor are the fans. btw AC clutch is not seized up.
I have a quick question, I got a 2005 mk4 gli, and when the cooling fans go on, only one works, the other one does not, I checked the fuse and its fine.
View 13 RepliesA few days ago I was driving around. I get back in my car and when i turn it on no air blows and the radiator fans aren't working at all. My car hasn't overheated but have stopped driving until I can figure the issue out. I have since replaced the fuse box on top of the battery to no avail. I was thinking that it could possibly be the fan control module but in all the posts I am reading not one says that theirs don't work, they just keep running. So is there something else i should be looking at?
View 1 RepliesSo with the car cold or hot . I turn the ac on and the motor rpm drops quickly and compressor kicks on . Can confirm this with someone watching with hood open. Low speed on both fans not working
Of I let the car idle in the for about 15 min then both fans high speed will kick on and run for a short time. Temp guage will always stay around 190. Car never overheats even in 95deg weather.
I tested the fans by jumping the 3 pin connector off the radiator and according to that test it's just the resistors on the low speed. So I ordered the nime control module.
So I completed the install of the OEM reverse camera with ECS wiring harness. I followed the wiring diagram, tapped into power at the back of the head unit according to this thread but nothing works. Neither the hatch lever nor the camera. I have to open the hatch manually from the inside.
I double checked the wiring diagram and everything is correct. I also plugged the old hatch wiring harness directly into the new camera by bypassing the ECS harness, and afterwards the hatch lever actually works... however, with the wiring harness installed, with the old hatch wiring harness inserted into the ECS wiring harness, the hatch lever does nothing.
Does the handle need power to function?
Did I tap into the wrong location for power? I was going to use a fuse tap, but couldn't get the fuse tap to plug in so I used the head unit. Where did people tap into for power? Did people use the red/white wire at the back of the head unit? I redid the connection with a simple twist joiner but things still don't work.... I also ran a new power line through the car to see if that would solve things. So is my problem:
1. faulty wiring harness
2. improper power supply
3. faulty camera unit
4. other.
So I noticed my temp gauge was starting to rise when I was on the freeway. I figured my fans were out but I just opened my hood and both fans were spinning. When I turned the car off both fans turned off but the temp gauge was almost into the red.
In the morning I turned on my AC and only the passenger side fan was working.
So I am not really sure what my next diagnostic step should be. The engine was not radiating any heat so I am not sure that it is even actually running that hot. Could it possibly be the temperature gauge? If I got a vagcom would I be able to check the actual temperature from there?
I am also concerned on how to find out if the fans are running at both speeds at the appropriate times.
Not sure if this is related but my cruise control stopped working a few weeks ago also.
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.

Well now I have to replace the multi function switch due to moving my steering wheel and the headlights sometimes working and turning signals not working. I saw a great video on youtube about changing a Multi Function Switch and it shows where the air bag needs to be removed. I was hoping that since my truck is an older 1997 F250 LD I wouldn't have to remove the airbag. Is there a way to do this w/out messing with the airbag on the 1997?
View 1 RepliesThe keyless entry for my Freestar has just started acting up out of the blue. It will occasionally work after repeated button pushing on the fob.
It does this for both fobs
It does this for all buttons on the fobs
I have tried changing the fob batteries
The door buttons inside the car work just fine
What can cause intermittent functionality of the keyless entry system? Is there a box under the dash I can unplug/replug or a fuse I can change?
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?
I have lexus RX350 2010. when i start the engine both fans are not working.
But when i turn the A/C on both fan start working. IS THIS NORMAL ?
This morning when I started up my car the coolant light flashed red, an audible warning chime sounded and the MFI read that I need to check the manual. Because the light was flashing, the manual says there is an engine coolant system malfunction and I need to take it to the dealer. The car was completely cold at the start, so I turned it off, then back on and there was no warning. I drove to work and the temperature gauge read right where it should be the whole way. This afternoon, when I started it up to go home the same thing happened. By the way, the car has only 4800 miles on it.
View 23 RepliesI'm curious whether something is wrong with the cooling function on my seats. While a +3 on the control seems to heat the entire seat rapidly and at a high temp, a -3 only gives me a moderate airflow out of the area under my thighs. Is the air supposed to flow out of the entire perforated region of the leather (upper back and inner-side sections) or is what I am experiencing normal?
Was thinking maybe I need to replace a component to get a stronger airflow out of the seat.
1999.5 golf afp engine cooling fans not working at all. fter run coolant pump also does not seem to be working. fcm changed still no luck fans do work when jumped straight to battery.

View 6 RepliesI just bought an 2008 Prius and I cannot for the life of me get the AUX function to work on my stereo. I have my iPhone plugged into the jack inside the center counsel, hit the DISC/AUX key and nothing. The cable between the iphone and jack is good, because I tried it on other devices and it works great. When I have a disc inserted into the stereo the DISC/AUX button works when switching from AM/FM radio to Disc and the cd plays. But when I have the cd removed from the stereo and hitting the DISC/AUX switch it does nothing. What am I doing wrong??? Or is the stereo broken????
View 4 RepliesCooling Fans and a/c compressor not working-2000 Grand Prix. They both work when I jumper them. Replaced coolant temperature sensor, checked fuses and relays -all good. Not sure what to troubleshoot from here.
View 4 RepliesI own a 2006 Prius with 52k miles on it. Great car BTW. The problem is simple, the radiator cooling fans stopped working on high mode; they run around 25% only even, not removing the heat from the a/c evaporator and the radiator coolant. I checked fuses: OK, checked relays: OK. They spin freely and nothing is blocking the front face of the evaporator. Funny I noticed it when I started hearing the a/c compressor buzzing noise and then I realized the fan noise wasn't there!
View 7 RepliesMy wife's 2009 Ford Flex has an intermittent radiator cooling fan issue. It has dual cooling fans and with the AC on, the passenger side fan runs wide open but the driver side fan doesn't run. With the AC off, neither fan runs even though I let the car idle for a long time to try and get it hot enough to allow the fan(s) to turn on. It doesn't matter if the engine is cold or warm, the passenger side fan runs extremely fast when the AC button is pushed. I've checked all connections and applied some dielectric grease to the connections. I also checked the fuses to the fans. Have to buy the entire dual fan assembly?
