Guys,
Thanks for the suggestions - was pretty late last night when I posted. Was working on another problem when I realized the problems with the central lock. Didn't think about finding another vac source.
I pulled out the seat and found that the foam housing for the pump was soaked. from a rain leak - assuming from the trunk. The electrical connections didn't look too wet. when I unplugged and plugged in power I could hear some clicking. The vac hose came off easily. once I disconnected the hose and reconnected. the lock actuators were manipulated by hand much easier. When I manually manipulated the locks and/or did so with a key, I heard no reaction with the pump. Don't have the tools to check leaks in the vac system.
By that time it was after 2am - So I gave up on it for another day. Thinking a little more clearly now - applying some vacuum should do the trick. Will have to try that. The key I have is the original - just think the lock needs replacing.
Thanks for the help!
