Replacing Vacuum Lock Actuator
 

Folks,

When I unlock the driver door, all works well... but when I unlock the trunk, all doors unlock except for the driver door. The lock comes up partially (about 3/4), but not enough to physically unlock the door. I'm guessing that this is the actuator.

I need to fix this, as I am putting in a BergWerks keyless entry system. As is, the keyless system will probably unlock all doors except for the driver door.

Where exactly is the actuator on a 94 E420? I took the door panel off and can't really see it. How hard is it to replace?

If your 94 E420 is like my 88 300e (which I'll assume it is) the actuator is very easy to replace. Now that you have the door panel off most of the work is done. To find the actuator, follow the yellow vacuum tubing in the door to the actuator. Shouldn't be very hard.
Anyway, I believe that it is held on by 2 or 3 screws but most importantly the actual lock is screwed in the tob of it. Unscrew these screws and the lock and it should come out.

Thanks. I think I have it now.
