I need a wiring diagram for my 1970 buick skylark. Wipers do not turn off, unplugged the switch and they still run. Checked and have power at the motor with switch unplugged. Anyone have any idea's where to start and there must be a relay under the dash? Thought the best way to go is start with a wiring diagram. Hope someone could helpout.. Thanks, Vin
i can think of 3 possibilities for the wiper motor continuing to run. 1) wiper switch not grounded 2) the park circuit in the wiper motor has failed. 3) short in the wiper motor
