Test A: The Wipers are Inoperative - Windshield

PINPOINT TEST A: THE WIPERS ARE INOPERATIVE - WINDSHIELD

Normal Operation
Under normal operation, when the ignition switch is in the RUN or ACCESSORY position, voltage is supplied to the wiper run/park relay coil through circuit CBP45 (YE). The wiper run/park coil is grounded at all times through circuit GD120 (BK/GN). High current voltage is supplied to the wiper run/park relay through circuit SBB03 (BU/RD). When the wiper run/park relay is activated it supplies voltage to the front windshield wiper motor through circuit CRW03 (VT/WH). The front windshield wiper motor is grounded through circuits GD123 (BK/GY) and GD120 (BK/GN). The multi-function switch is grounded through circuit GD111 (BK/BU). The front windshield wiper motor receives open and ground inputs from the multi-function switch through circuits CRW17 (GN/VT), CRW18 (VT/WH), CRW19 (BU/OG) and CRW08 (VT/OG) to activate the wipers to the appropriate modes.

This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Relay
- Wiring, terminals or connectors
- Multi-function switch
- Windshield wiper motor
