Good morning!
The metal grille off the tweeter cover on the driver side door keeps popping off.
Any recommends for a permanent fix?

 

This happened to mine also, the plastic by the screws that hold the tweeter in gets brittle with age and breaks. I took mine out and rebuilt it with epoxy. It might also be one of the lug has broken of the cover, same process, rebuild with epoxy.

Last time I looked the parts were either nla or too expensive from the dealer.

 

I used a tiny bit of dynamat(sound deadening material) made into a tiny roll and put it in the groove of the plastic piece. The grill stick to the dynamat very well.
