Golf IV / Jetta IV :: Only One Of Radiator Cooling Fans Working
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 RepliesFord - Flex :: 2009 - Radiator Cooling Fans Won't Working
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?

A 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 RepliesGolf IV R32 :: Overheating - Radiator Fans On - Cruise Control Stopped Working?
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.
Camry :: 2003 Camry 2.4L - Cooling / Radiator Fans Stay On All The Time
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.

My 2001 alero 3400 engine is getting hot again this alero is running with a 2001 impala engine run great for few months, replace radiator, hoses, thermostat and suddenly coolant start leaking in the overflow, fans not working even with ac on, i replace the etc sensor and did not work, the fans turn on when I disconnect the etc sensor so i think the fan motors are ok. I got one pcm module from the salvage yard in case I need to replace it but I read that only the dealer can reprogram the computer system because vin number issues....

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 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?
Golf IV / Jetta IV :: 2002 - A/C And Both Fans Stopped Working?
So 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.
Camry :: Cooling Fans Will Not Come On Except When AC Turned On And Stop Working When AC Turned Off
2003 camry 2.4 ... This is what is happening, cooling fans will not come on except when the AC is turned on and they will stop working when the AC is turned off, otherwise the car will over heat.
This is what I have done...Replaced the fans (because the radiator fan was bad, after hooking them up directly to the battery). I checked all the grounds, including the one under the intake, checked the fuses, checked relays using 12vots to the relay and used a ohm meter to see if it made contact when activated, on the three fan relays. Replaced and tested the new radiator sensor using a pot of water on the cooking stove with a cooking temperature gauge and ohm meter. It tested ok.
Unplug the radiator sensor while the car is running, the fans will come on, but go off as soon as it is plug back in, even when the motor is over heating. Also replaced the thermostat.
What can I do next, before I burn the motor up trying to fix it? Motor just started running rough. Just now pulled up a code of the number three cylinder miss firing
Lexus GS 2006-11 :: Starter Doesn't Engage And Radiator Cooling Fan Comes On
08 Lexus GS350. Drove car Christmas Eve everything was fine, Christmas morning I go to start the car and it attempts to start once and before it cuts on it stops. Then anytime afterwards when I push the start button the starter doesn't engage and the radiator cooling fan comes on. I let the car sit for half a day and try to start it again I get the same cycle (it engages the starter but quits before the car turns over)...
- Battery is new as of September 14 (also took the battery to get checked 100% charged).
- I replaced the alternator in November 14
- I currently have the car at my mechanics but they can't figure it out as of yet. So far they are saying that the can't the cars computer to respond to their machine.
Golf IV / Jetta IV :: 2004 - Overheating / Fans Stopped Working Correctly And Fuses Kept Blowing
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.

Celica :: 1991 - Cooling Fan Stopped Working
My cooling fan just stoped working the other day (not sure why) i replaced the fuses and relays they are all good. Now when i unhook it from the radiator fan switch it turns on but plug it back in and well it shuts off, i put a new switch to see if it will work but it started running real rough and hard to start so i put the old one back on and nothing changed. I read the book and checked everything but still nothing and why my engine light came on and it started running rough.
its a 91 celica 1.6 (4AFE)
Scion - Tc :: 2012 - A/C Stopped Working - Radiator Fan Not Getting Power
So I have a scion tc 2012 and the A/C no longer works properly. The AC blows lukewarm air (seems to just blow whatever air is outside) when I press the AC button, it doesn't kick on the compressor. The heat works fine. I took it to a shop and they tested the pressure and said it was good. They can plug in a scan tool and make my car blow cold air but it won't work without the scantool, the scantool can kick on the compressor. They checked all fuses and relays. They tried replacing A/C amplifier and they tried replacing (A/C switch?). Now they want to charge my $350 to fix drier and evaporater. If that's not it they want to replace the compressor.
This is getting expensive fast, and they haven't even actually diagnosed the problem! Also the radiator fans don't seem to power on either.
