Normal Operation
Under normal operation, the rear window wiper motor receives power through circuit SBB30 (BN/RD) and circuit A_CBP12 (GN/WH). The rear window wiper motor is grounded through circuit GD150 (BK/WH). 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.

Possible Causes
- Fuse(s)
- Open in circuits CRW20 (GY/YE), CRW21 (YE/VT), SBB30 (BN/RD), A_CBP12 (GN/WH) or GD150 (BK/WH)
- Inoperative rear window wiper motor
- Inoperative multi-function switch
