i think the foam has some adhesive on it already so i just pressed mine back onto the metal. i pushed gently on the vent from the top to see if it still wanted to move. once i got it settled, the vent trim seemed to stay in position. i don’t think you’d want to get rid of the foam because it probably reduces/mitigates trim-to-metal contact noise.Thanks. Now, what is the fix for this foam piece? Cut it off? Tape it up? Any thoughts?
