Test A: The Wipers Are Inoperative
PINPOINT TEST A: THE WIPERS ARE INOPERATIVENormal 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 internal wiper motor module controls the internal wiper run/park relay to control the windshield wiper motor in conjunction with the internal wiper high/low relay. The windshield wiper motor receives voltage from circuit 2026 (RD/OG) and is grounded through circuit 1205 (BK). The windshield wiper motor internal microprocessor and relays receive voltage from circuit 2025 (RD/YE) and are grounded through circuit 1205 (BK).
This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Wiring, terminals or connectors
- Windshield wiper/washer switch
- Windshield wiper motor
