I'm puzzled, my '89 300E door locks have been acting strange lately. If I
unlock the car from the passenger side - only that door opens and none of the
other locks even twinge. However, if I unlock the car from either the driver
door or trunk, then everything unlocks, 'including' the passenger door.....
I'm stumped, anyone have any ideas? Much appreciated!
Many thanks for that Tiger!! Wouldn't have thought of that. In a lot of
ways I'm still thinking along the lines of my old 240D. You got vacuum from
the engine and that was that, no extra pump. So I was thinking either you
got vacuum or you don't, so what gives with the doors.... :-) live and learn
I just had this problem with my '92 300D only it was the driver's door
that had no effect on the other locks. In my case the vacuum pump was
the culprit. That it worked at all from the passenger side sounds a bit
counterintuitive but replacing it cured the problem.
