From what I understand from research, the radiator cooling fan has to be running when car is idle. Mine is not. I tried switching the relay and fuses under the hood, but that did nothing. Then, I saw that you could hook jumpers from the fan directly to the battery, so I tried that, and the fan didn't come on. Would it be more than likely that the fan motor went bad?

    If you have power going to the motor and it does not turn, ya the motor has a problem.

    So, I got my new fan and it doesn't turn on. I checked the fan by jumping it from the plug directly into the fan, not through the controller (?) Would that have made a difference? I thought I had to start with the source closest to the fan and work my way backwards.
