Questions about radiator cooling fans. Mercury Grand Marquis.
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?
