Rear Left Door Lock Actuator Motor for 2020-2021 Chevrolet Silverado 1500 & More - Dorman 937-055

Designed to lock and unlock the rear left door on command, the Dorman door lock actuator motor (part number 937-055) is an integrated door lock actuator engineered as a direct replacement for the stock actuator. It fits many vehicles, among them the 2020-2021 Chevrolet Silverado 1500, 2020-2021 Chevrolet Equinox and 2020-2021 GMC Sierra 1500. See the "Vehicles it fits" section for the full list.

• Reliable replacement: put through extensive quality and safety performance testing.
• Perfect fit: engineered to match the original actuator's fit and function on the listed applications.
• Safety compliant: subjected to simulated crash testing under government guidelines.
• Cycle tested: tested in an actual vehicle door to verify effective use for years.

The door lock actuator is the motor-driven unit inside the door that moves the lock mechanism when the power lock switch or remote is used. Signs it may need replacing include:

• a rear left door that won't lock or unlock with the power controls
• locks that work only intermittently
• a buzzing or clicking sound from inside the door

Because a switch, fuse or wiring fault can cause similar symptoms, diagnose the cause before replacing the actuator. This listing is for the rear left door position.
