4 Signs of a Failing Door Lock Actuator

A door lock actuator is an electronic device that operates power locks in a car's doors. The device, usually a solenoid or reversible motor, controls the locking and unlocking of vehicles at the touch of a button. The device is located at the driver's door seat or on a vehicle's dashboard, and it's meant to eliminate the need to manually lock or unlock your car's doors. Sometimes the door lock actuator might fail, making it difficult to open the door. Keep reading to discover four signs your door lock actuator is in need of repair.

1. Strange Sounds Coming from the Inside of the Door

A faulty door lock actuator produces grinding, clicking, or clunking noises when you open the door. If you hear strange sounds from the inside of a car's door, it is an indication that your door lock actuator is faulty.

2. Erratic Operation of the Power Door Lock

A faulty door lock actuator can sometimes cause your vehicle's door locks to operate erratically. For instance, if an actuator has a wiring problem, it can cause a car door to lock and unlock at various times while you’re driving or while your car is parked.

3. Malfunction of the Door Lock

When an actuator fails, the power door lock feature is rendered inoperable. While you can still manually lock and unlock the door, the power functionalities are disabled.

4. The Door Lock Operation Slows Down

If you notice that your car door is operating slowly, the door lock actuator is probably failing. Although a weak actuator can still operate a door, it causes slow responses which can be frustrating.
