I have an FD without a sunroof and on the passenger side where the headliner meets the door frame the headliner is sagging. I tried to take the trim off and put the headliner back then push the trim back up to hold it, but the headliner dosen't want to stay.

Is there some kind of adheasive or something that is supposed to hold the edges of the headliner up?

A search only turned up interior swaps and "the headliner is easy to replace, the carpet is the hard part."

Any help would be appreciated.

 

No one else had thier headliner do this?
