Normal Operation
With the key in the ON position (or with the delayed accessory function active), pulling the window control switch up or pressing the switch down supplies voltage to the window motor. Depending on which circuit has voltage supplied determines which direction the window motor operates. The window motor operates in the commanded direction to move the window up or down.

Possible Causes
- circuit 985 (RD/LB) open
- circuit 1205 (BK) open
- driver window control switch
