Window Sub-Switch

When ignition switch is in ON position, battery voltage is applied to the power window relay through appropriate fuse in the dash fuse box, energizing the relay. When relay is energized, battery voltage is supplied to the master switch assembly through closed relay contacts. When a window sub-switch is operated, battery voltage is applied to the appropriate power window motor. The motor is then grounded through the opposite contact in the respective window sub-switch and master switch assembly.
