Rear Window Lockout Feature

WARNING: This page is about a different car, the 2002 Oldsmobile Aurora and 2001 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.

The rear window lockout switch is built into the Driver Door Switch Assembly (DDSA). When it is pressed momentarily , the LED indicator is illuminated, and the DDSA receives the switch signal. The DDSA sends a message over the power door serial data line to the driver door module (DDM) indicating that the switch is active. The DDM then sends a message over the power door serial data line to both rear door modules prohibiting the rear windows from being operated from the rear door window switches, or, to all of the passenger door modules prohibiting any passenger window from being operated from its associated window switch. The passenger windows can still be operated from the driver door by using the passenger window switches built into the DDSA.
