I need the steering wheel wiring diagram for my 1992 Chevy Cavalier I have to unhook all of the wire's from the steering wheel column to shut the car off or the battery will go dead. What is the problem I have checked for shorts on all the wires and there is no shorts and my fan has a certain switch to turn it off I have to turn the fan on everytime or my car will overheat and I have to shut it off when I get out of the car?
