Bug Deflector Noise

[ironhead3fan]

I put a bug deflector on my truck just after I bought it a year ago. I don't remember the brand, would have to go out and look, but is pretty much goes with the shape of the hood. Ever since, the noise in the interior has steadily gotten worse at speeds over 60 mph. Does anyone else have this problem? I really hate to take the bug deflector off. Thanks.

Mine has done the same thing since I put mine on, almost sounds like something is lightly on the windsheild or something is loose in the post between the windsheild and door, Can't seem to find out what it is either. noise is worse when it's windy too.

Years ago, when I put one on my Avalanche it made a new sound I had never heard from my truck also. Someone figured out that the rubber up the side of the window was lifting and slapping the window. To kill the noise, a strip of 3M double sided tape was run under the edge of the rubber. That slapping/popping noise was corrected. I don't know if that is the same noise you guys are hearing but that was the fix on those.
