auto door closer switch

Does anyone have any experience with these? I'm talking about the microswitches that when triggered, pull the doors closed with the vacuum assist. I have had my driver's door apart to get a look at it and from have a good handle on the procedure to replace one. BUT.....The first time I got in to this area was two months ago when the driver door failed to pull itself closed. That's why I looked inside. Found out it was likely the microswitch as the culprit. I have not yet replaced it, and a week ago, the fron passenger door stopped pulling itself closed too! :X This morning, I had the car parked in a heated garage...put something in the back right side...door closed itself fine. Pulled it outside, and had to get in back right door again. Now it does not pull itself closed. Then immediately went to trunk to check and it had stopped pulling itself closed. :wall: The only one to still remain working is the left rear door. WHAT"S GOING ON!!!??? Are they beginning to fail in series? Does one fail after the other if another is bad? PLease help before I go mad, or install new microswitches without needing to.

RE: auto door closer switch

[:)]What makes you think it is the micro switches?
these failures are usualy traced to vacume pump problems. You have two pumps by the way. Have you checked them?

RE: auto door closer switch

Sorry not related.

This is the reason I don't want
a new MB.
I'm perfectly able to close the
doors myself and only adds items
to check when something fails.

My 83 300TDT has electric windows
only because it came with it,I would
swap them for manu cranked ones in a
hard beat if it wasn't such a hassle
to do.

Yes check the vac system first.
