Weird... I had/have the same problem in my driver's side rear door! I was able to diagnose the problem when I took off the door panel. (I noticed the problem because the door would unlock about 5 seconds after the rest of them, and I could hear air escaping. The vacuum pump would also stay on longer to fix the loss of vacuum, or so I'm guessing).
Well I took off the door panel and could hear the air escaping not from the vacuum line, but a black rubbery peice that connects the vacuum line to the mechanism (actuator?). Well I noticed that when I pushed on this black thing, that the air could barely escape. So I shoved something (I think a fuse puller?) between the black peice and the inner of the door frame, thus pushing on the actuator (?). It solved my problem, and has stayed that way for about 4 months now. I expected only a temp fix (knock on wood, burl or zebrano of course!) and I seemed to have gotten a permanent one, or so we'll see.
Anyway, take off your panel and let us know what you come up with.
