Power Windows

The operation of the power windows is controlled by the master switch on the driver's power window switch. When the main switch is off, only the driver's door window can be opened or closed. With the master switch in ON, all windows can be opened or closed by the driver's power window master switch or each window by its respective switch. The driver's window switch also has an automatic down mode which is controlled at the driver's power window switch.

The power windows are driven by reversible motors. Each motor is protected by a built-in circuit breaker. If a window switch is held on too long (with the window obstructed, or after the window is fully up or down), the circuit breaker opens the circuit. The circuit breaker resets automatically as it cools.

When the ignition switch is in RUN or START, voltage is applied to the coil in the power window relay. The contacts of the power window relay close and voltage is applied to the driver's power window switch, the power window control unit, and the passenger's power window switch. When the ignition switch is turned from RUN or START to ACC or OFF and both front doors are closed, the integrated control unit will keep the power window relay energized for approximately ten minutes or until one of the doors is opened.
