i noticed on the two arm pillars on the rear door panels that thy aree seperating around the electric window panel , anyone else have this problem any one ever replace there arm rest, and how much might they be?nd are they hard to remove

 

^^ I have this problem to on the back left door. Never bothered to fix it though. Mine isn't that bad but I'm never in the back anyway.

 

get some glue or epoxy and stick it back

 

many have had luck gluing them back into place. I would take the door panel off and glue it and set something heavy on it over night while it dries
