Normal Operation
When the accessory delay relay is energized, battery voltage is provided to the driver window control switch through circuit 193 (YE/LG). The driver window control switch is grounded through circuit 57 (BK). When the driver window control switch is moved to the window down position, voltage is supplied to the driver window regulator motor through circuit 227 (YE) and ground is supplied through circuit 226 (WH/BK). When the driver window control switch is moved to the window up position, voltage is provided to the driver window regulator motor through circuit 226 (WH/BK) and ground is supplied on circuit 227 (YE).

Possible Causes
- circuit 226 (WH/BK) open or short to ground
- circuit 227 (YE) open or short to ground
- driver window regulator motor
- driver window control switch
