When a door stops locking or unlocking from the switch or remote, the Dorman door lock actuator motor 746-163 is designed to take over the job of the failed original by electrically driving the door lock mechanism. It fits many vehicles, among them the 2004-2008 Ford F-150, 2002-2010 Ford Explorer and 2005-2010 Ford Mustang. See the "Vehicles it fits" section for the full list.
This non-integrated Dorman lock actuator is a standalone actuator, separate from the door latch. It is cataloged for the front left and rear left door positions, and it serves as a direct replacement for the stock actuator on the listed applications.
- Reliable replacement: Dorman put this actuator through extensive quality and safety performance testing.
- Built for the original fit: Engineered to match the original actuator's fit and function on the listed applications.
- Safety compliant: The part has been through simulated crash testing under government guidelines.
- Cycle-tested: Dorman ran cycle tests in an actual vehicle door to confirm it works effectively over years of use.
Signs this part may need replacing include a door that will not lock or unlock with the power switch or remote, a buzzing or grinding sound from inside the door, and locks that work only some of the time. Diagnose the cause before replacing, because wiring or switch faults can produce similar symptoms.
