Im working on a buddies 72 corvette wiper motor. The wiper motor works but it does not go back into the park position. Also there is this resistor on a part where some of the wires connect for changing the speed and I do not know where the resistor tail goes. It kind of just hangs out in the air. Does anyone have a wiring diagram for in the wiper motor for a 72 corvette. It seems like this wiper motor setup is very similar to other gm vehicles throughout the 70s. Basically I need to figure out where the resistor tail connects and how to test the park solenoid switch assembly.
