I don't know where to start looking for the cause for this problem. Sometimes when I turn my car off one or both fans stay on and do not go off until the batrtery is dead. Usually it is just the passenger side cooling fan that stays on but both have been on as well. I have the otterstat jumpered to keep the fans on when the car is running (I have a new one ordered. This problem happens whether or not the otterstat is bypassed or not. I turn the car to on and then off and the fans will go off. Thanks for any help.
