What is wrong if the cooling fan comes on when the coolant sensor is unplugged but when it is plugged in the fan and AC will not work?
I have seen this before more than likely your coolant sensor has a internal short and needs to be replaced.
Your coolant temperature goes up at low speeds and the fan will not come on in your 1994 fire bird what is wrong?
Either the fan motor or the sensor needs to be replaced. or your thermostat is stuck.
Coolant fan will not come on?
If the coolant fan does not operate on a Chevy Corsica, it is likely that a fuse is out. There could also be a mechanical defect in the fan or wiring.
89 Maxima over heating What could be wrong?
Low coolant? Radiator plugged or restricted? Water pump not circulating coolant? Cooling fan not working? Thermostat not opening? Cooling system airbound?
Why would the coolant fan stay running when the keys are out of the ignition in a 1998 dodge caravan?
The coolant fan is triggered by a temperature sensitive switch. when coolant reaches a certain temp it turns the fan on. When the coolant drops below that temp it shuts off the fan. The ignition switch plays no part in the operation of the cooling fan.
What else is wrong 92 beretta gt changed head gasket kit new fan new fan relay new temp sensor new rad bottle cap fan not coming on and antifreeze is blowing out of the bottle?
someone obviously did your head gasket wrong. if it's a 3.1, did they bleed air from system using the valve on coolant rail. this can cause air trapped in the system to boil the coolant.
What is the cause of excessively high coolant level in the coolant recovery reservoir?
coolant fan
Where is the fan control unit on a 1997 VW Jetta?
I have a 1996 Jetta. If you have the older body style then it is directly beneath the round coolant expansion tank, attached to the strut tower. It is a black rectangular box with fuses under a clear plastic cover. You'll need to unscrew the coolant expansion tank to get at the fan control module. It is susceptible to being doused with coolant which might cause the fan control module to short.
Why don't the coolant fans on your 99' Cutlass work?
The coolant fan may have a blown fuse. The electric motor, on the coolant fan may be not working. The ground wire on the cooling fan may be corroded or loose.
Does the ECM and the fan work off the same coolant sensor on a 92 grand am 3300?
I could be completely wrong, but I think they share the same sensor. If there's two sensors for the coolant, one usually goes to a gauge and the other is used by the computer, which in turn controls the fan activation and speed.
What does the fan do in a car engine?
cools the engine. without a fan, the car will overheat and the coolant will boil. the fan controls this from happening by cooling the coolant as it passes through the radiator.
What is wrong if your 1997 Grand Am GT overheats even after you've replaced the thermostat water pump and radiator and the fan clicks on when it is supposed to?
You probably have a cracked head gasket!!!!! You probably have a cracked head gasket!!!!! Check coolant to see if there is oil in the coolant this will prove it or if you have foam in coolant overflow check coolant resevior cap
