Check your radiator fan switch and your fan switch coolant sensor .
Blown fuse, bad fan motor, defective thermal switch or a bad fan relay. Or check the coolant temp sensor.
fan motor could be grounding internally Unplug the fan switch and ground the wire if the fan stops replace the switch. If not you have an open between the coolant sensor (switch) and the relay. The coolant sensor for the fan is not the same sensor for the computer/fuel injection.
The coolant fan switch is located close to the thermostat.
no switch,fan control is determined by the engine control unit with input from the coolant 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 =)
Where is coolant fan switch located on 1998 chevy Malibu with 3 .1
When standing in the front of the car, the first sensor is the coolant temperature sensor. The second one closer to the car bulkhead is the thermostatic auxiliairy fan switch sensor.
Check to see if you are getting power to it with A/C or defroster on Try Hot wiring the motor to see if it is defective Check fuse and relay Check temperature sensor switch XXXXXXXXXXXXXX ANSWER XXXXXXXXXXXXXXX The temperature sensor works the light or gauge. The cooling fan switch works the cooling fan. If, when the air conditioner is "ON," the fan works then there is no need to hot wire it. If the coolant is low in the radiator and isn't contacting the switch, then the fan will not work. Open the radiator cap and be sure the coolant is full. You can have a full recovery tank and a low radiator and the coolant will not transfer.
Cooling fan thermo switch is located on the radiator edit - only if fitted. Some fiat fans are controlled by the ecu, using data from the coolant temp sensor.
The fan switch on a 1995 Acura Integra is located on the dashboard. It is a part of the temperature control system.
The fan switch is the same as the coolant temp. sensor. It is located next to the thermostat "goose neck". Follow the radiatoer hose on the Right , standing in front of the vehicle.
