Power Door Lock Actuator: Description and Operation
Models equipped with the optional power lock system have a power operated door locking mechanism located within each front door. The lock
mechanisms are actuated by a reversible electric power lock motor that is integral to the door latch unit within each front door. A single short pigtail wire
with a molded plastic connector insulator connects the door lock motor to the vehicle electrical system through a take out and connector of each front
door wire harness.
The power lock motors cannot be adjusted or repaired and, if faulty or damaged, the entire door latch unit must be replaced.
On models with a base version of the Central Timer Module (CTM), the power lock motor is controlled by the battery and ground feeds from the power
lock switches. On models with the high-line or premium versions of the CTM, the power lock motor is controlled by the battery and ground feeds from
the power lock and unlock relays, which are integral and internal to the high-line and premium versions of the CTM. A positive and negative battery
connection to the two motor terminals will cause the power lock motor plunger to move in one direction. Reversing the current through these same two
connections will cause the power lock motor plunger to move in the opposite direction.
The power lock motors and circuits can be tested using conventional diagnostic tools and methods.
