WARNING: This page is about a different car, the 2004 Pontiac Sunfire and 2004 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
The body control module (BCM) controls the driver door lock actuator. The ground is applied to the door lock actuator lock control circuit through the door lock portion of the door lock/unlock relay. When the body control module applies power to the driver door lock actuator unlock control circuit, the door lock actuator energizes and unlocks the door lock.
