When I bought my '04 9-5 a few days ago, one of the things I noticed was the front passenger door trim was coming off a little and had a gap between it and the black trim by the window. I have tried to push it back in and for some reason it won't stay (as soon as someone closes the door it pops back out). Anyone have any experience with taking the door trim off and can tell me what holds it in or why it might not be staying in when I place it back?
