Circuit Description
WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.
The power sliding door module (PSDM) supplies the power and ground to operate the power sliding door (PSD) clutch, which is part of the PSD clutch/motor assembly. Upon receiving a PSD request, the PSDM supplies 12 volts battery positive voltage through the clutch control circuit to the clutch. The clutch is grounded via the clutch ground circuit to the PSDM. With the clutch energized, the sliding door cables are mechanically connected to the PSD motor and the sliding door is powered to either the open or closed position. When the clutch is de-energized, the sliding door can be operated manually.
