Pinpoint Test A: The Wipers are Inoperative

Refer to Wiring Diagram Set 81, Wipers and Washers for schematic and connector information. Diagrams By Number

Normal Operation

During normal operation, the wiper motor receives voltage at all times from Battery Junction Box (BJB) fuse 49 (30A), through circuit SBB49 (RD). The wiper motor also receives voltage, with the ignition switch in RUN or ACC positions, from Smart Junction Box (SJB) fuse 45 (5A) through circuit CBP45 (YE). Ground is provided to the wiper motor through circuits GD120 (BK/GN). The multifunction switch sends open and ground input signals to the wiper motor through circuits CRW08 (VT/OG), CRW18 (VT/WH), CRW17 (GN/VT) and CRW19 (BU/GN). The multifunction switch is grounded through circuit GD133 (BK).

This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Wiring, terminals or connectors
- Multifunction switch
- Wiper motor
