First, you will need to check the fan good functionality. Ulplug the radiator fan and connect the wires directly to the battery. Check if the fan is running. If not, that's the fan needed to be replaced.


I have had same occurance not in the same car but other electronic fans cooling off the radiator.make sure your fluid level in radiator is correct. If not the antifreeze won't reached the censor causing the fans not to respond. Or simple as the relay is bad. Check fuses!!

Does the radiator fan come on when you turn on the A/C?


The thermostat may be bad - if it is not registering, your fans won't kick on.
