I finally got the door panel off and removed the door lock/handle. It seems as if everything is OK with it, it pushes in and out smoothly, and locks OK so now Im thinking that it is NOT the door handle.
As I was loosening the bolt that holds the "end" of the handle to the door, I heard a pop, and the thumb button popped out from it's stuck in position. so I then tried the door knob and it worked OK as long as the screw was not tightened . Evidently , as I tighten that screw, the door handle moves more parallel to the door , and the forked mechanism at the end of the thiumbpiece moves more towards the outside edge of the door, which loosens something that was binding up.
Its hard to explain, and I can not see what is causing it to bind, or can not even move my fingers in there to feel anything
Any ideas what is happening???
