I had my radiator fans replace two times already. The shop did some wiring work. My car has been doing fine for about two weeks now. Today I turned it off and it is making that noise before the radiator fans failed last time. Do you know what keeps causing them to fail

Check the coolant level in the radiator. Does the coolant temp. Gauge show overheating? Seems like engine may be overheating causing fans to overwork, growling may be from coolant boiling in radiator.

Ok, if it's already been pinpointed to an electrical issue and you say the wiring and relay have been replaced then I would suspect a bad powertrain control module (PCM). It is the vehicle's computer and could be sending wrong signal making more volts go to fans than should be, which will burn out the system quickly.

Unfortunately really no way to test the PCM, just have to swap with a known good one and see if it cures problem. It's just a box with a few connectors plugged into it as far as replacing it yourself.
