Door Jamb Switches

WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

The front door lock cylinder switches are internally integrated within the door lock assemblies. The body control module (BCM) monitors all door jamb switches via a discrete input from each door jamb switch, including the rear door(s). If the BCM receives a ground signal from a door jamb switch when the CTD system is armed, the BCM activates the alarm.
