Prius (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!

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.

Some years back my "farm" '05 prius when a host of bells and whistles went off, cooling fan ran more than normal, and I lost power a couple of times. Turned out this farm prius had an accumulation of dirt, dog hair, hay and other debris that needed to be cleaned out. You got me through the whole process, and the car's run fine until.... . Fast forward a couple of years to 200,003 miles. Now the cooling fan is running pretty constantly, the red triangle stays lit, the check engine light comes on, the (!) is on, and the VSC light is on. Haven't hooked it up to check codes, but did check cooling fan and it's clean. Would it possibly possibly better to change the 12 volt battery?

My 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?
View 3 RepliesGolf IV R32 :: After Settings On Auto Fans Constantly Running?
So I replaced my big fan today. Everyone knows that the factory fans are notorious for going out. After replacing the fan, I turn the car on and noticed that both fans were on... and never turned off. So I turned the car off, and turned the car over again. and they still were constantly running. I messed with the climatronic controls and when I have the settings on auto the fans are constantly running, when I have it on econ, they don't run. And when its on neither, the fans are constantly on unless I turn it off. Before replacing the fan, I replaced both the FCM, CTS, and the fan switch. Its becoming pretty frustrating. I supposed it could act as my own switch for the fans, hahaha. I've searched and havent found anything like this. Hopefully its something small

View 12 RepliesGolf IV / Jetta IV :: 2001 - Cooling Fan Constantly Running?
I've decided the first issue w/ my new-to-me jetta I want to focus on is the cooling fan constantly running. I suspect this is potentially related to the temp gauge not reading anything, which I suspect might be because of the coolant temp sensor.
So basically, when I turn the key to on (I'm pretty sure it's on, not start), one of the cooling can comes on. It's the fan on the right side as if you are sitting in the driver seat. I've been looking at the wiring diagram for this issue as well, and the only other thing I can think of that isn't a computer involving issue would be the thermo switch. But it seems like both fans should be coming on in that case, and it's definitely only the one fan that is coming on.
Chevrolet - Lumina :: 1999 - AC Compressor Clicked On But Cooling Fans Not Running
99 lumina. Ac was not working. I added a few oz's and the compressor clicked on but cooling fans were not running. After 10 min of idling the fans did come on but went off after 1-2 minutes. It seemed like they were responding to coolant temp more than ac pressure. Do the fans run when the hi pressure rises to a certain point where the computer will turn on fans?

My 2003 camry LE 4 cyl cooling/radiator fans stay on all the time. As soon as I turn the ignition key both radiator fan start to spin even though the car is cold and not on. I checked all the relays and fuses. Checked the voltage on the coolant sensor harness with ignition switch on, there is no 5v or the green pin is not grounded. I am clueless where to go next.

The two Radiator fans are always running even at start up on a cold day. I have not had time to investigate as yet but I am assuming it is the temperature sensor located near the thermostat or a relay. No CEL on. What it likely is and how to approach the trouble shooting?
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?
Prius (Gen 3) :: Battery Cooling Fan Constantly Runs At Every Highway Trip
The past week I have noticed my battery cooling fan running constantly on all highway trips - 20 mile one-way trips going 65-70MPH.
The performance of the battery doesn't seem be degraded, but it seems like the battery is hopping more between charging cycle or whatever you would call it , where you watch the instantaneous MPG on the highway drop down for 10 seconds to 40-50, then back up to 60-70.
The car is a 2011 Prius III. It did not run like this earlier in the summer in the same weather conditions, I would hear the fan maybe once every few weeks in hot 90 degree weather. Now I hear it constantly. This is my first summer owning the Prius so this may be normal, but I wanted to double check with you all if this is a sign of premature traction battery death or something.
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) :: Vacuum Pump Running Constantly And Rattling?
I had the doors open while unloading the car this morning and noticed that the brake booster pump just kept running and running and running, plus I can hear a strange, hollow rattling sound somewhere under the car that coincides with the pump. When I say it runs "constantly," I really mean that it runs for 10 seconds (with the rattle), stops for about 5 seconds (silence), runs and rattles for ten seconds again, stops for another five, and just keeps on going for as long as I care to sit there with the door open.
