Description & Operation

The power window switches are located in the door trim panel armrests. The master control lock-out switch is located in the driver's door armrest and can be used to deactivate all of the individual power window switches. Single power switches are located on all door trim panels except the driver's door. These switches allow activation of the power window for individual doors only.

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.
