try turning on the fan switch in the car
you might have to replace your water pump, coolant, or coolant fan switch wich is located behind the power steering fluid. If none of those work you might have a vacuum leak
Either go to a shop that has Alldata or a parts house and ask them to give you an illistration of the coolant fan switch or purchase a Haynes Manual that is specific to your car.
It's located on the passenger side head. Let me tell you, it's very delicate and breaks easily.
Blown fuse, bad fan motor, defective thermal switch or a bad fan relay. Or check the coolant temp sensor.
On my 91 RS 305, the coolant fan sensor is located next to the thermostat cover on the top-front of the intake manifold. If your fan is not coming on, it my be a bad coolant fan switch. The coolant fan switch is screwed into the block above the starter. It provides a conditional ground to the fan once the temperature reaches 225F. I replaced my coolant fan switch 3 times and my fan still wouldn't come on so I finally gave up and permenantly grounded the wire for the fan switch. So for the last 3 years, my fan runs continuously while the ignition switch is on. I also replaced the fan motor with one with a life-time gaurantee for $25.AnswerWrong, the coolant FAN sensor is on the right side of the engine (if you are standing in front of the car facing it) under the exhaust manifold, the coolant sensor next to the thermostat only controls the temperature gauge in the car. =) That might explain why you replaced it 3 times and it never worked =)
Check your radiator fan switch and your fan switch coolant sensor .
Not that I am aware of. Are you sure the body control module is the problem and not the power or grounds. You may even have a bad fan switch.
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.
You probably have a bad coolant temperature switch, this are fairly cheap and easy to install.
does your car have A/C? If yes theres a a/c fan switch located by the a/c compressor
If you are talking about the coolant temperature switch that turns the fan on when the coolant reaches the right temperature, then mine it is located in the bottom of the radiator directly under the fan.
