Driver and Passenger Door Lock Operation (with Keyless Entry)
WARNING: This page is about a different car, the 2002 GMC Savana Special, 2002 GMC Savana Camper Special, 2002 GMC Savana, and 2002 Chevrolet Chevy Express. However, it is still accessible from the selected car via links, so may be relevant.
On vehicles equipped with keyless entry, the passenger and rear door lock actuators lock in the same manner as described above, however, the driver and the rear door lock actuators have the door lock motor unlock circuit connected to the remote control door lock receiver. The remote control door lock receiver internally grounds the driver door lock actuator and also provides a pass through circuit for the rear door lock actuator to the door lock motor unlock circuit and then to normally closed contacts of the unlock relay to ground.
