Hello,

I have a 2007 silverado NBS crew cab with a sun roof. When I drive between 35-40 MPH, I get a high-pitched whistling noise that seems to be coming from the top center of my windshield. I've put my hand all around in that area and around the sunroof while driving and the noise persists. The noise sounds exactly like a hearing aid whistle. The noise is also more prevalent on warmer days. I plan on bringing the truck into the dealership, but figured I'd see if anyone else has had this same issue. Thanks in advance!
