Rear Tailgate Door Lock Actuator for Buick Rainier HYR7O9HP

Product Description

A door lock actuator plays a critical role in your vehicle’s central locking system by converting electrical signals into mechanical movement. This allows your doors to lock and unlock smoothly using your key fob, switch, or automatic locking system.

When the original actuator begins to fail, you may experience issues such as delayed response, intermittent locking, unusual noises, or doors that stop locking altogether. Replacing a worn actuator helps restore proper door operation and improves everyday convenience and security.
