Product Details

Here is a great way to save some money repairing your old Mercedes vacuum door lock actuators. When they go bad it is almost always due to cracks in the rubber diaphragms. These can be easily replaced once you remove your door panels and remove the units. Order only one or as many as you need. Four are required per actuator and you have three actuators in the left rear door and both right side doors. There is no way to tell how many rubber diaphragms you may actually need until you remove the actuators, inspect and test them.  On some cars you may only need to replace one or two. On others cars you may have to replace all.

NO INSTRUCTIONS INCLUDED: They can be purchased separately. Look below to order.  NOTE: Instructions for removing the door panels on the various models are also available separately. See my other manuals for information on door panel removal.

Here is an actuator with torn diaphragms removed from a door from a 116 chassis 280S 280SE 350SE 450SE 450SEL 6.9 and 300SD ( note 2 rubber diaphragms on top and two on the bottom. This is similar to the 123 chassis 240D 300D 300CD 300TD 280E and 280CE 1977 to 1980

Below is an actuator from a 114 and 115 SEDAN 1973 to 1976 ONLY. (Will not work on 2-door coupes). When they go bad it is almost always due to cracks in the rubber diaphragms. Note on these cars on two diaphragms are used per actuator
