Running Fan 1990 LeBaron

I have a 1990 Chrysler LeBaron that the radiator fan will not stop running all night and day when the car is off. It caused the battery to drain. Any information to fix this will be appreciated.

Thankfull

Hmmmm... sounds like you got a dodgy sender unit.. change the sender and the thermometer should help.. if not you got a short somewhere in the engine bay.. 1st check and see if you replaced the wires in the right place if you done some work recently..:)
