The black trim above the windshield occasionally comes loose on the passengers side. But not at the end, that stays connected and the trim forms a bow between the center and the end. I push it back and it seems to fit and stays in place for a few weeks.
What is supposed to hold it in place? Maybe im missing clips or something?

When it is pulled away/loose and you can safely pull it to make a little room, clean thoroughly with alcohol and use some water sealer, very thin film, and push back in place. Do this when you can push in place and let sit for a couple days in a dry place.

Or, ask a glass business the best thing to do.

It is possible to address this issue without replacing the entire windshield glass by applying a thin bead of urethane in the channel of a new lace molding (P/N 88980304) and then roll it onto the windshield.

If you want 3 new windshield trim pieces ,





[H3]Condition[/H3]

Some customers may comment on noise coming from the windshield and door area.

[H3]Cause[/H3]

This condition may be caused by the installation of a hood air deflector. The deflector may change the path of the air across the vehicle, causing the left side and right side windshield reveal molding to make noise.

[H3]Correction[/H3]

Replace the left and right side windshield reveal molding. Refer to the Windshield Side Reveal Molding Replacement procedure in SI.

The fix in the first thing I posted can probably be done in your current molding if you dont want to buy s new one by just cleaning out the channel if it has old urethane and then reapplying
