Circuit Description
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 driver and front passenger door lock switches provide a path to ground for the driver door lock switch signal circuit to the body control module (BCM) through a 470 ohm resistor when the door lock switch is activated to the lock position. This input is used by the BCM to control the door locks.
