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 switch is operated, driving the door lock lever in or out. The rear doors have no power lock buttons, only manual lock levers. The power door lock switches are generally closed for just a moment. If they are held closed for too long, an electronic circuit breaker in each actuator will open to protect the motor against damage. These circuit breakers have Positive Temperature Coefficients (PTC) and will reset automatically when voltage is removed from the actuator. When either the L/H or RH front power door lock switch is activated. all of the doors are locked or unlocked in unison. Each door lock actuator assembly contains a manual door lock lever 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 and move the lock actuators. When the drivers door key cylinder is turned, all doors will unlock. The key locks and manual lock levers will still work if electrical power is lost.
