Theory Of Operation: Notes

By studying the schematic above, you will notice that the window driver circuits both go to ground when the switches are in the neutral position. In the driver switch, when a switch is moved to lower or raise a window, the switch leaves the ground contact, and supplies 12 volts to the Master Window Switch Rear Up or Down circuit. Likewise in the rear switch, when a switch is moved it leaves the ground contact and supplies 12 volts (through the window lockout switch output circuit) to the Rear Window Driver Up or Down circuit.
