Golf IV R32 :: Cooling Fans Not Turning On And A/C Not Cold
The last few times I drove my car, I noticed the A/C didn't feel very cold. I checked today, and noticed that neither cooling fan comes on with the A/C on. My understanding is that both fans should be in LOW mode with the A/C on. Also, after idling for a while and even after doing some spirited driving and pulling over, the fans never turned on.
From what I'm reading, this sounds like it probably is either the fan control module or the fans themselves failed. Is the fact that both fans don't work in either high or low speed point to this being more likely to be a fan control module? Would this show up as a fault code on a VAG-Com scan?
Golf IV R32 :: Cooling Fans Continue To Run Until Battery Disconnected
After about 3 weeks, I finally get my 04 .:R32 back from the shop after getting a new fuel pump (long story there) and the mechanic mentioned the fans began to run and stay running when the key is turned to the on position and then turned off, key removed etc. I picked the car up tonight and repeated his claim turning the key to the on position and the fans kicked on and stayed on until the battery was disconnected. I am hoping there is an easy fix. What this could be? FCM maybe?

My 03 Golf ac is not working and i am looking for a wiring diagram/ troubleshooting chart. the cooling fans turn on low and I hear the engine surging like the compressor is trying to cycle but it is not.. When I jump the low pressure switch the fans go to high and no power to the compressor. I get a flash of power to the compressor but just a blip every ten seconds. I am trying to check continuity of the ac clutch but having a difficult time getting in there hot. I just bought the car and fixed light body damage on the right front but it was not even bad enough to hurt the washer bottle. Hard to believe the hit caused damage to the ac? AC seems to be charged with about 100 psi static pressure. Why are diagrams so hard to find?

View 2 RepliesGolf IV / Jetta IV :: 2001 - Misfire At Idle - No Cooling Fans?
I have a problem I can't seem to figure out. My car has a misfire at idle. It has stumbled every once in a while at idle before while at Red lights. Now it does it all the time. Check engine light is on and I got 5 codes. P0300, p0301, p0302, p0303, p0340, and p0012. The last two are for cam position sensor. I took it outo and looked at it. Looks fine. I reinstalled it and hand cranked the motor with a meter hooked up and I am reading about 10 volts when it senses the metal ring going around. So I think that is good. I sprayed brake cleaner on all the hoses to see if the motor reved to hopefully find a vacuum leak. Nothing. I also noticed today that my cooling fans or my ac don't work. Now I have another issue to deal with. I checked all my plugs and wiring and coils also.

I need a way to make my both fans be on constant during track days, I know induction makes a fan kit for the mk4 r32 which works great but the controller in the MK5 is different and the kit don't fit.

Had the car for about a week, Autobahn with lighting pack, leaving home is set to fogs. So when its dark out and I have the switch in auto, obviously the fogs come on when I unlock the car, as soon as I push the button to start the car the headlights will come on for a microsecond, shut off, then start up again and stay on. This happens about 99% of the time and it can't be good for the ballasts.

My independent mechanic says my radiator fan and AC fan are cycling too much. The dealer says they are not. I know it started about 6 months ago and that I get 2 miles per gallon less now. If the heat, defrost selector is in any position it happens as long as the fan control in not on off.The fans run for 5 seconds and then are off for 20 seconds. The independent says the AC has refrigerant but doesn't know what is causing it. It happens at all outside temperatures. It happens at all car temperatures. (Just started, been driving for an hour etc.)

Ok, to start off. I have a 2010 2.0T CCTA with 23k miles. I recently purchased a HPA Intake Manifold and installed it myself. I was told by HPA that they offer a tune specifically for their manifold. I however, purchase the Maestro suite by Eurodyne with the intention on getting it all tuned myself. I was able to code out the CEL for the flappers no problem. Now my only issue is the cold starts. During the cold start cycle I get misfires and air surge. I ran the fault reader and got the P0300-P0304 (Misfire faults). Obvious thing to check were plugs and packs. So I changed them. No change.
I read in a bunch of threads that these faults as well as air surge are a sign of the PCV Valve. I have a catch can kit on order so I will see if that wotrks. My guess is no. Another thing I think it could be is the N75 valve however, this issue only occurs during the cold start cycle. After the cold start cycle is done I have no issues what so ever. So I ruled out the N75 valve. If it was bad, then it would be bad regardless of how cold/warm the engine was. I have attached a video of the Cold Start.
Camaro :: 2000 - Cooling Fans Won't Come On
I have issues that are drivin me crazy. Cooling fans not coming on. I was driving and smelled antifreeze, I immediately looked at gauge was at 210. So I stopped to check, right side of radiator was split. Put new radiator in waterpump and thermostat. As the car was running during the flush process it started spewing so shut it down gauge was 210. Plugged in Modus ran codes were none for overheat. The cooling fans are not coming on while car is running, but I can turn them on with the with the modus so fuses and relays are all good. The one thing that puzzles me why it works with modus but not by itself. If that's not enough started a couple weeks ago sometimes when hitting bumps loose power to windows, radio, convertible top, and then hit a bump and it starts working again. I have been all under the dash and hood checking connections and grounds to no end.

My 97 lesabre cooling fans won't come on. the car gets pretty hot when driving around town. I saw on another form that they should come on when the Air Conditioning is on but mine does not. I got the fan to come on when connecting it directly to the battery so i know the fan is good. I replaced the high speed relay with the horn relay and still nothing.
Im not opposed to putting a switch in the cabin but im not sure the best way to go about doing that.
Touareg :: 2004 V6 - Cooling Fans Always On
I own a 2004 V6 Touareg as I have been going to the dealership for the last three months now and they cant solve the problem.
Once I start my car in the morning, immediately both cooling fans start running and they wont stop until I shut down the car, it takes them about 10 min to shut down.
Bonneville :: Cooling Fans Not Coming On
In the process of resurrecting my 93 SSEI after running at idle for awhile the engine was pretty hot. I noticed the fans never came on. I unplugged the temp sensor and both came on. So would the problem be the temp sensor, thermostat, or relay. I am not sure what the actual engine temp was because my Cluster only works when it wants to, usually when its warmed up and going down the highway or when I mat the throttle.
View 10 RepliesPrius (2004-09) :: Cooling Fans Won't Come On
I have 05 prius and the cooling fans wont kick on as well as the ac wont work. I have had the cooling fan motors checked they are good. I have changed the 2 cooling fans relays and the cooling fans still wont kick on.
When I bought the car the check engine light was on so I had it scanned and it threw the code P1121 coolant valve control. so I went and bought this part since I heard it was a common problem but haven't got it put on yet. Could this cause the cooling fans to not kick on and ac not to work or is it something else?
Passat (B6) :: 2006 - Cooling Fans Won't Shut Off
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
View 19 RepliesCamry :: 2004 - Cooling Fans Not Turn On At Any Stage
I have a 2004 Camry that the cooling fans won't turn on at all. I checked one of the cooling fans by running direct power and it worked. I then checked all the fuses relating to fans and A/C. Then checked relays by using the horn relay in Fan 1 and Fan 3, which are both 4 pin. I bought a new relay for Fan 2 as it was a 5 pin and still no change. The fans don't come on at any stage, turning on A/C or letting the car idle to the point of the water boiling from overflow. I'm thinking it's not the sensors as the fans should turn on when the A/C is turned on.
