Title
Repairing Mercedes W123 Early Style Door Lock Vacuum Actuator
Introduction
The door locks on many W123 Mercedes Benz (1977-1985) are locked and unlock using vacuum produced by the vacuum pump on the engine. Leaks in the door lock system can cause the door locks to operate poorly. One place to being is by checking and, if need be, repairing the vacuum operated lock actuators. The main "moving part" is a set of rubber diaphragms that, with age, get brittle and crack. With this guide, you will learn how to repair these actuators.
