Power Locks: Description and Operation

Circuit Operation

The C-7 DOOR LOCK fuse applies battery voltage at all times to the door lock control unit (in left front door power window and lock switch). Locking or unlocking the doors with either door lock switch locks or unlocks all the doors. The control unit locks or unlocks the doors by applying battery voltage and providing a ground to the door lock actuators in one direction to lock the doors, and in the opposite direction to unlock the doors.
