Circuit Description
WARNING: This page is about a different car, the 2002 Pontiac Montana, 2002 Oldsmobile Silhouette, and 2002 Chevrolet Venture. However, it is still accessible from the selected car via links, so may be relevant.
The rear side door actuator control module supplies the power and ground to operate the power sliding door actuator motor and the actuator clutch. The direction of the actuator motor rotation is determined by which of the control circuits is supplied 12 volts and which is grounded. The rear side door actuator control module varies the current flow through the actuator motor ground circuit to control the speed of the actuator motor as necessary. The actuator clutch enables the power sliding door to be operated manually when de-energized, or by the actuator motor when energized.
