1.Leaking actuators

Every door lock in your vehicle operates with an actuator. When they fail, it can lead to problems locking one or more door.

Depending on what type of Mercedes you drive, the actuators will work differently and require different attention.

For instance, some Mercedes’ actuators are equipped with rubber diaphragms that can generally be replaced easily and inexpensively.

The point of this pump is to suck in and blow out air that controls the door locking mechanism.

If the pump begins to fail, it can directly impair the ability of the doors to lock, and this can be easily solved by a Mercedes specialist.
