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. If the power door locks are commanded for too long, a 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. The manual key locks and lock levers will still work if electrical power is lost.
