I have a number of problems with the driver's door (not the door itself) on my '92 500SEL, and I am thinking somehow they are inter-related. Trouble #1: Both speakers in the door don't work, about 90% of the time; trouble #2: The vacuum-assist door-closure is non-functional.....all other vacuum devices are fine; trouble #3: The door will not lock with the remote....all other doors and trunk lock/unlock just fine. Could this be a problem with tubing/wiring where it enters the hinge side of the door just because of age and obvious use of that door over 165,000 miles? If so, how does a person access that part of this vehicle to check, or for that matter, get the door panel off? I would appreciate some insight from anyone else who has seen these kinds of troubles.

getting the door card off is not that difficult...

remove the plate on the edge of the door - chrome jobby.

in the handle of the door pupp is a small (1/2" long, 3/8" wide) cover for another screw - vertical or nearly.

in the middle of the top 'leather' bit is another on mine - but mine has airbags. about 10 (for left door) o clock, 1/3rd of the way in as you look at it.

another under the handle iirc...

rest are pull off - dont use much force

vac pipes are obvious.

Search the archives for my name and W140 door. There are step-by-step instructions in the thread for removing the door panel.

I don't remember the symptoms with my W140 but the problem was a broken actuator rod between the central lock actuator and the lock button.
