Normal Operation
With the ignition key in RUN or ACC, the windshield wiper motor receives voltage at all times from the wiper PARK relay through circuit A_SBB09 (RD). When the wipers are commanded OFF, the smart junction box (SJB) deactivates the RUN/PARK relay. Voltage is supplied from the park switch (integral to the wiper motor) to the RUN/PARK relay through circuit CRW09 (BN/BU) to operate the wipers until they are parked. When the wipers are parked, the park switch (integral to the wiper motor) supplies ground to the RUN/PARK relay and the wipers will stop. The SJB monitors circuit CRW09 (BN/BU) for voltage when wipers are not parked and ground when the wipers are parked.

Possible Causes
- Open in circuit CBP23 (BN/YE), GD121 (BK/YE), SBB09 (RD), A_SBB09 (RD) or CRW09 (BN/BU)
- Short to voltage in circuit CRW09 (BN/BU)
- Windshield wiper motor
- PARK relay
- RUN/PARK relay
- SJB module
