noise after 100km/h

[Fabio]

Hey guys, hope all is well, i just put on a hood guard/bug deflector on a 2007 silverado classic on the highway when going near and over 100k i'm getting a noise that something is loose or rattling on the windshield driver side lower part close to the wiper. I have looked at everything can't find the problem, any help would be great......Thanks

It's the rubber trim at the windshield L and R edges. Remove them, and reinstall with some double sided tape between the trim and glass. You can also use RTV sealer (just a small bead), but that makes it a little more difficult to replace the glass (and is a little less effective than tape). The trim can be removed by opening the doors, and accessing the screws in the door frame.
