Shucks. This problem was from a year ago and no one offered up any help other than "gently squeeze it back"? I can tell you, that didn't work for me. My glovebox cover did the same thing. My entire cover came off, not just a corner of it like the OP (although I think that may have been how it started).It's like it was glued and gave way, but there's nothing really in the way of glue residue. A year later, has anyone else had experience with this and did you glue it back or replace the entire door?
