Re: 68 Wiper ??????
The wiper motor gets 12V from the yellow wire. The wiper switch grounds the other wires to activate the motor. You might get our your volt meter and see if you have 12V on the other wires with the switch off and ensure ground is applied when the switch is in various positions. That should isolate the switch, wiring, and motor.
