Normal Operation
With the key in the ACC or RUN position the voltage is supplied to the coil side of the accessory delay relay through circuit 297 (LB/PK). When the accessory delay relay is energized, battery voltage is supplied to the driver window control switch on circuit 193 (YE/LG). The driver window control switch provides voltage and ground to all other window control switches. The driver window control switch is grounded through circuit 57 (BK).
