    This bulletin is being revised to add model years. Please discard Corporate Bulletin Number 08-08-48-003E (Section 08 - Body and Accessories).Condition
    Some customers may comment on hearing a tapping, clicking or ticking noise at the windshield area. This condition occurs more frequently while driving at highway speeds and could be exaggerated on vehicles with front bug guard deflectors.
    Cause
    This condition may be caused by air/wind causing the windshield side reveal moldings to move, generating a noise.
    Correction
    Remove both windshield reveal moldings, add double-sided tape and re-install the moldings following the steps below:

    [TD]Using tape (1) or a grease pencil, mark the position of the inboard edge (2) of both left and right reveal moldings onto the windshield, following the contour of the molding.[/TD]

    Tip
    An approximate 600 mm (24 in) length of tape should allow for overlap at the top to be trimmed back leaving a tail of release liner (1) and, at minimum, should reach the fender cut line at the bottom.

    is it worse/more common after or during a rain? i have had the same problem in my truck, i was told its due to a not quite perfect seal on an aftermarket windshield, i actually noticed water leaking in at the top of the windshield on the passengers side one day

    Strange noises (solved for me!)

    Hello everyone and Happy Holidays to the forum: After having my truck for a year now, I had the same noises coming from the windshield area on both sides of the windshield. 2010 Silverado Crew cab LTZ 4 x 4 Diamond White Pearl.

    This Summer it only happened a few times but the colder weather it happened all the time. I drive the Ohio Turnpike everyday at up to 75 - 80 mph and it does make noise.

    Finally I recently changed out my chrome 20" wheels and tires for my 17" snow tires and wheels(not related) to the noise but it is when I fixed the noise problem. After changing my oil and filter, I thought about the noise thing. ALL I did was get my black silicone in my caulking gun and raised the side windshield trim up slightly and injected the silicone into the opening between the windshield and the side trim. I then lightly pushed down the trim to seal it. I let it set over night and the next day "NO NOISE" at all. Hope this easy fix works for the rest of you. No need to remove trim, go through all the other steps listed in this thread, this does work and easy too!
