Windows: Description and Operation

The Master Power Window Switch in the driver's door and the Passenger Power Window Switch send current to the Window Motors. Current flows in one direction for UP and the opposite direction for DOWN.

When the switches are in the "at rest" position, they ground bother wires of each motor.

To raise the window, current flows through the UP side of the switch through the motor circuit breaker, through the motor, and through the DN side of the switch to ground.

To lower the window, current flows in the opposite direction.

Each motor assembly has a circuit breaker to cut off power if a switch is held too long in the UP or DN position.
