Normal Operation
Under normal operation, the instrument cluster module (ICM) grounds the accessory delay relay through circuit 1332 (LB). Power is sent to the master window control switch through circuit 400 (LB/BK) from the accessory delay relay. The master window control switch is grounded through circuit 57 (BK).

Possible Causes
- Fuse
- Open in circuit 400 (LB/BK) or 57 (BK)
- Window control switch

CAUTION: Be careful when probing the CJB, battery junction box or any connectors. Damage will result to the connector receptacle if the probe being used is too large.
