Door & Tailgate Locks - General Motors - Actuated: Description

The electric door lock system uses a permanent magnet motor lock actuator assembly at each door, conventional switches and a relay. All doors lock and unlock manually or from the door control switches. An instrument panel switch is used on station wagons equipped with a tailgate lock only. Buick wagons use a lock relay; all other wagons with tailgate lock only use a polarity-reversing switch system. Camaro and Firebird models also use the polarity-reversing switch rather than a lock relay.
