This requires some good observation when taking them apart, so's you can
put them back together correctly. 
I've rebuilt my locks due to corrosion. What I found was that, after
cleaning all of the surfaces, there are these 2 tiny springs that keep
the contacts where there supposed to be. Both of these springs were
toast. An easy way to replace them is to cut a spring from a ball point
pen in half (fits perfectly) for replacements. I think what's happening
is one of the contacts is touching, but the other is not when it's
supposed to. Try it out and see what happens.
Have fun!

Subject: FW: latest problem.... the power door locks

Well after finishing my fuel pump, I got about 5 miles of trouble free
driving. After parking and locking up, my passenger door will not stop
pulling the lock pin down. If I unlock the passenger door, it
IMMEDIATELY
goes back down. If I unlock it and open it, it pulls back down the
instant
the door is closed. I guess something is stuck. Anybody got any
experience
in there?

One thing after the other..

Hey at least I don't have a car payment ;)
