Door Lock Actuators

The power door lock actuators receive their power from the door modules. The door modules apply battery voltage of the correct polarity to their respective door lock motors when any door lock or unlock command is received, driving the door lock lever in or out. The power door lock switches are generally closed for just a moment. If the power door locks are commanded for too long, an circuit breaker in each actuator will open to protect the motor against damage. The circuit breakers have Positive Temperature Coefficients (PTC) and will reset automatically when voltage is removed from the actuator. When either the left or right front power door lock switch is activated, all of the doors are locked or unlocked in unison.. When the driver's door key cylinder is turned, all doors will unlock via the power lock system. The key locks and manual lock levers will still work if electrical power is lost.

Each door lock actuator assembly contains a manual door lock lever. The rear doors have no power lock buttons, only manual lock levers. The lock levers move with actuator position and may be used to independently lock or unlock any individual door at any time. Both front doors have key cylinders that will unlock and lock the doors by manually moving the front door lock actuators
