I have a powerlock problem -- switched drivers and passengers locks out and still didn't fix it.  here goes:

driver side works great, no problems at all.  On the passengers side, when you either push the lock down from inside or use the key on the outside, the lock goes up, then pops down again.  (vice versa if car is already unlocked).

If you open the passenger door while this is happening, the lock will repeatedly keep attempting to go down, with no successs, until you shut the door.

The side door and back door follows the leader.  While all this is going on, however, the drivers lock is doing nothing at all. (not attempting to go up or down)

Any suggestions???  Thanks, Oliver
