Windows: Description and Operation

The Window Switch in each door sends current through the Window Motor in one direction for UP and in the opposite direction for DN. The current causes the Window Motor to turn in a clockwise or counterclockwise direction, raising or lowering the window.

In the OFF position, both motor wires are grounded through separate switch contacts.

When the DN switch is pushed, power flows to the DN Motor lead. The UP lead acts as ground. When the UP switch is pushed, power flows to the UP motor lead. The DN lead acts as ground.

The Power Windows are protected by inline Circuit Breaker 12. Each motor assembly also has a circuit breaker to cut off power if a switch is held too long in the UP or DN position.

The Window Safety Relay allows operation only when the Ignition Switch is in the ACCY or RUN position.
