This is for the air conditioning system
Remove the wiring harness from the back of your 1999 Cadillac Escalade radiator fan motor. Remove the radiator fan motor retaining bolts. The radiator fan will come off.
maybe check the thermostat.
The water temperature sensor on a 2002 Kia Sedona is located on top of the engine, near the upper radiator hose. It relays the temperature to the vehicle's computer and triggers the cooling fan to come on.
When you say "cooling fan", do you mean the radiator fan or the cabin air fan? If the radiator fan and the compressor are failing to come on, it could just be low refrigerant but in either case there is no guarantee that any single component would cause what you describe. It could be a fuse, relay, controls, connector or any of a number of possible causes.
The fan blade would be connected to it.
Check the thermostatic switch
Problem with the temp sensor.
It is important to have a working radiator fan. If it does not work, a person needs to check the wiring and its fuse.
check thermostat. check engine fan coolant sensor possible locations radiator or thermostat housing. check electric fan working
The fan itself, its fuse or thermostat.
Depends on how long the car was running. Let the car run for an hour at idle and if it never comes on, I would check the fan. It should come on at sometime. Check the relay..............I just had this problem on my '89 Beretta. DoratheExplorer
