Lift Glass Ajar 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.
If equipped, the lift glass ajar switches use a discrete input to the BCM. The BCM utilizes these inputs from each lift glass ajar switch. If the BCM receives a ground signal from a lift glass ajar switch when the CTD system is armed, the BCM activates the alarm.
