Test B: The Wipers Are Inoperative - Rear Window

PINPOINT TEST B: THE WIPERS ARE INOPERATIVE - REAR WINDOW

Normal Operation
Under normal operation, the rear window wiper motor receives power through circuits SBB19 (BU/RD) and CBP43 (GY). The rear window wiper motor is grounded through circuit GD149 (BK/GY). The rear window wiper motor receives open and ground inputs from the multi-function switch through circuits CRW20 (GY/YE) and CRW21 (YE/VT) to activate the wiper to the appropriate speeds. The multi-function switch supplies a ground input to the rear wiper motor on CRW21 (YE/VT) when INT 1 is selected. The multi-function switch supplies ground to the rear wiper motor on CRW21 (YE/VT) and CRW20 (GY/YE) when INT 2 is selected.

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