Question type: Maintenance & Repair

Fuses are ok, what else should I check

1 Answer


...for your radiator fan, which is what i assume your talking about, aside from the fan, which needs to be tested as well, there is also a radiator fan relay, and a temperature sensor that tells the computer when to turn on the fan, then of course, there's the wiring going to and from everything, and the computer itself..... i had a car where the computer was bad, at least for that function, and wouldn't send the "turn on" signal/voltage to the relay.....
