Normal Operation
The windshield wiper motor receives open and ground inputs from the windshield wiper/washer switch through circuits 56 (DB/OG), 58 (WH), 61 (YE/RD) and 63 (RD) to activate the wipers to the appropriate modes. The module (internal) controls the wiper run/park relay (internal) using internal circuitry to control the motor in conjunction with the high/low relay (internal).

- Wiring, terminals or connectors
- Windshield wiper/washer switch
