SInce I have te pasenger side door panel off o dela with the door not openning, I figured I would try and fix te tweeter door handle trim that keeps popping off. There doesn't seem to be anything broken. It seems to atleast partially snap in but pops off th minute yo use the handle.

try very very gently bending the tabs so they grab easier. most commonly, the tabs on either the tweater housing or the trim are broken, in which case you need a replacement or to get fancy with some glue.
