Description & Operation: Operation

A dual-winding electric motor moves the tailgate power window up or down. The direction the motor runs depends on which winding (raise or lower) is supplied with voltage. The dash-mounted tailgate power window control switch and tailgate key switch determine which winding is supplied with voltage.

When either switch is turned to RAISE position and the tailgate block-out switch is closed, voltage is applied to the raise winding of tailgate power window motor. The motor runs and the tailgate power window goes up.

Voltage to lower the tailgate window is applied through the lower contacts of both switches to the lower winding of the tailgate power window motor.

When the tailgate is opened, the tailgate block-out switch prevents tailgate power window from being raised.
