Radiator fan doesn't turn on and thus my car overheats. Could this be the radiator cooling fan motor that doesn't work? Or do I have to replace the entire radiator fan?
Do you
have the same problem?

Hello,

Does your vehicle have 1 or 2 fans? Also do you have A/C? If so turn the A/C on, do the fans come on? If so most likely it is your Coolant Temp Sensor. It is locate on the front of the engine in thermostat housing.

Sorry, for delay in responding.

Ok, do you know the location of the Radiator Fan Relays? They are located in the Relay Box on drivers side in engine compartment... You will need to check them... Here is a diagram...

Check out the link below for relay testing....

If relays test good then try straight wiring from battery to fan plug.
