Normal Operation
When the accessory delay relay is energized, battery voltage is supplied to the driver window control switch on circuit 193 (YE/LG). Operation of the accessory delay relay is controlled by the lighting control module (LCM) through circuit 194 (PK). Voltage is then distributed to the front and rear passenger window control switches from the driver window control switch on circuit 170 (RD/LB). The front and rear passenger window control switches are grounded back to the driver window control switch on circuits 313 (WH/YE), 314 (TN/LB), 316 (YE/LB), 317 (BY/OG), 319 (YE/BK) and 320 (RD/BK). The driver window control switch is grounded through circuit 57 (BK).

Possible Causes
- circuit breaker
- circuit 57 (BK) open
- circuit 193 (YE/LG) open or short to ground
- circuit 194 (PK) open
- circuit 768 (BN/YE) open
- driver window control switch
- accessory delay relay
