Normal Operation
Under normal operation, when the washer is selected, the multi-function switch provides ground to the smart junction box (SJB) through circuit CRW07 (GY/BN). When the SJB commands the washer ON, ground is provided to the washer relay coil through circuit CRW14 (BU/WH). When the washer relay is energized, voltage is sent from the washer relay to the washer motor through circuit CRW24 (GY).

Possible Causes
- A short to voltage in circuit CRW24 (GY)
- A short to ground in circuit CRW14 (BU/WH) or CRW07 (GY/BN)
- Washer relay
- Multi-function switch
- Smart junction box (SJB)
