View 2 RepliesPrius (Gen 2) :: 2006 - Radiator Cooling Fans Stopped Working
I 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 RepliesPassat (B6) :: Fans Blowing On Super High After Car Is Shut Off
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.

So, over the past day and a half my beloved B6 has been putting me through the wringer... Sunday morning I fire it up, drive to church, turn the car off and everything is fine. Church is over, I drive home, turn the car off and my cooling fan keeps running... I go inside and check again in about 15 minutes hoping it had shut off after 2 minutes or so, but nope, still running. So, in order not to kill my battery, I disconnect it. I let it sit for a few hours and went back out hoping that leaving the battery disconnected would reset something, but as soon as terminal touched the lug, the fan kicked on again.
Now, for the electrical issues that have come with this problem... Whenever I hook the battery back up, a few things can (and usually do) happen. The steering and traction assists don't work, the parking brake malfunctions, the transmission shifts HARD (if feels like somebody is rear-ending me), occasionally the transmission just stays in 3rd gear, and all of the PRNDS emblems in the dash readout are highlighted as if they're all in gear at the same time. Now, cut the car off and back on a few times and most of these issues go away, but other times I've got to fight it a while and disconnect/reconnect the battery for everything to fix itself. I popped my scanner on it, because it's throwing a CEL as well, and aside from the P0304 misfire code (stupid intake valve crud...), I'm occasionally getting P0864 - TCM Communication Circuit Range/Performance. Not sure what's going on, but it seems like my car is self-destructing...
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.

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?
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?
Camry :: 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.

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?
View 20 RepliesCaravan/Voyager :: 1998 - Engine Cooling Fans Won't Go On
I have a 1998 Caravan and the engine cooling fans wont go on. Ive replaced the relay and the temp sensor. When I pull the connector off the temp sensor the fans go on so I know the fans and fuses are fine. For some reason it seems the computer module isnt sending a signal to the relay to turn the fan on. I get the trouble codes P1491(radiator fan relay circuit fault) and P0118(engine coolant temp circuit high input).
I am also having a problem with the air conditioning not working. When I do the self diagnostic test on the A/C the results are that it fails the cool-down test. Why the computer module isn't sending a signal to the relay? Could the A/C problem be causing the cooling fans not to come on?

View 13 RepliesGolf IV R32 :: Cooling Fans Cycle On And Then Off Every Three Seconds When Start The Car?
Why recently the fan comes on when I start the car, then a few seconds later it turns off, then a few seconds later it's on regardless of outside temp or engine temp? Is this simply caused by a malfunctioning green coolant temp sensor? What type of electrical Gremlin causes our cooling fans to cycle "on" and then "off" every three seconds?!
