I agree with what both of you said. What turned out to be the problem was a fuse. Not blown, but glazed over on it's contacts. I couldn't tell just by looking at it. It was not blown. But since I was getting a weak continuity reading from the passengers door lock plug I felt it had to be either a wire coming apart or the fuse. I cleaned the spades of the fuse with emory cloth and the fuse box with electronics cleaner and everything works fine now. This was a very frustrating problem for me but it worked out fine. I guess the good news is that I became very familiar with what's inside my door panel and how to remove it really fast. I've never encountered a glazed fuse. Wonder who else has had that problem and paid for the repair of something else.
