if cooling fan is not turning on you need to check fuse. then check fan thermostat . and switch, can also be bad motors check them.
Check the cooling fan relay and the control sensor. Check the fuse as well and if these are all good, check the fan motor.
check the cooling fan sensor somewhere attached of the fan housing.
check the coolant temp. sensor, this sends info to the computer to turn on the cooling fan. Check for other answers for the cooling fan, I posed a answer on how to replace the fan relay with out removing the front facia and bumper
Check ebay motor section
Check the fuses, check the relays and check the temp switch.
its a pulley fan, it never goes bad
get in the car when it is cold, turn on the ac, then check under the hood. the fan that is not spinning when the car is cold is the cooling fan
Check the fuses, check the relay and then check the fan motor.
When it's running hot you should hear the cooling fan running, if not that is your problem. If the cooling fan does not operate check the fuses, cooling fan relay, cooling fan switch and cooling fan motor. One of them is at fault.
Check the underhood fuse box.
If the engine cooling system fan, check the fuse/relay to see if the it has blown out. If not the fuse/relay, the cooling system temperature sensor switch may have failed. For he A/C system auxiliary cooling fan, the same trouble-shooting method. If you are referring to the cabin interior circulating air fan - check the fuse and/or the switch that controls the fan speed.
