Power Door Lock Actuator: Description and Operation

In the power lock and Remote Keyless Entry (RKE) systems, the locks are actuated by a reversible electric motor mounted within each door and the lift-gate. The power lock motor direction is controlled by the battery and ground feeds from the power lock and unlock relays integral to the Passenger Door Module (PDM).

The power lock motors cannot be repaired and, if faulty or damaged, the entire motor must be replaced.
