: radiator fan not spinning

07-22-06, 05:40 PM
I've been having problems with overheating. With the temp at 210 today, the radiator fans on my 99 Deville was spinning slowly and then stopped spinning. Ahha! Since both fans are behaving the same way, I was guessing that is wasn't the motors but there would be something else keeping them from running, maybe bad wiring? Just looking for suggestions or other experience. Thanks.

If I am reading my manual correctly the fans don't even come on until the temperature reaches 229 degrees. The fans will switch to high speed if the temp reaches 234 degrees. This is if the AC is off, the fans run all the time if the AC is on.
