Door Lock Vacuum Actuator Repair Kit Video for Mercedes W220 S430 S55 S600 HD

If your car door lock actuator is not working properly, a common problem is that the plastic air reservoir (at the bottom of the actuator) is broken or cracked. Air leaks will cause the actuator to not be able to pull the door to the close position. This rebuilt kit is designed to fix the problem without changing the complete assembly.
