Hi, my rear door seems to be inoperable. Specifically, the exterior door handle/opening mechanism does not allow me to pull the handle far enough, to the point where the door latch is released thus allowing the door to pop open. Just prior to the complete failure, when I went to open the door, it seemed as though there was a point at which the opening mechanism started to bind up but with a little additional force I could get it to move beyong that point of seizure and the door latching mechanism would release the door and allow it to open. I meant to take the interior panel off to see if there was something to lubricate but now I can't do that because I can't open the rear door.

Any suggestions would be appreciated.
