Windows: Description and Operation

Each Window Switch applies voltage to its Window Motor, causing it to turn in a clockwise or counterclockwise direction to raise or lower the window.

The Switch sends current through the Window Motor in one direction for UP and in the opposite direction for UP and in the opposite direction for DN. In the AT-REST position, both motor wires are grounded through separate switch contacts.

When the DN switch is pushed, voltage is applied to the DN motor lead. The UP lead acts as ground. When the UP switch is pushed, voltage is applied to the UP motor lead. The DN leads acts as ground.

Power Window circuits are protected by Circuit Breaker 24. Each motor assembly also has a self-resetting circuit breaker to cut off power if a Switch is held too long in the UP or DN position.
