When the rear left power lock on your Cadillac stops responding, the Dorman door lock actuator motor, part number 931-398, is designed to take over the job of the original. This integrated door lock actuator is a direct-fit replacement for the rear left door of the 2008-2014 Cadillac CTS. See the Buyer's Guide tab for engine and body-style details.
The actuator is the electric unit inside the door. It moves the lock mechanism to the locked or unlocked position when the lock switch or remote sends the signal. Dorman designed this unit to deliver the same fit and function as the original actuator on the listed applications.
- Tested for reliability: This Dorman lock actuator has been through extensive quality and safety performance testing.
- Built to match the original: It is engineered as a direct replacement for the stock actuator in the rear left door.
- Safety compliant: It has been put through simulated crash testing under government guidelines.
- Cycle-tested: Cycle testing in an actual vehicle door is used to verify effective operation over repeated use.
Signs this part may need replacing include a rear left door that no longer locks or unlocks with the others, locks that work only some of the time, or a buzzing or clicking sound from inside the door. Wiring, switches and fuses can cause similar symptoms, so diagnose the cause before you replace the actuator.
