We have had a couple of cold fronts come into my area recently. I've been driving in the 25-30 mph wind that has accompanied these fronts. If I drive the car into a quartering head wind on the right side of the car, I pick up very loud buzzing sound. If I turn the car around 180 degrees and go back over the same stretch of road, there is no buzzing sound. This usually occurs above 45 mph. If there is no wind or only a very light wind, below 15 mph, no buzzing sound is created. This has happened on two separate occasions.

Have any of you experienced this? Know what could cause it? I've looked in the wheel well and there doesn't seem to be anything flapping around. If you tap around on the inner wheel linings, there is a hollow, tinny sound. But that is in all of wheel wells. This only happens on the right front corner of the car.

Do a search, it's the plastic trim below the windshield. I think some have used double sided tape to fix it.

Had my glass guy take care of an issue like this for me last summer.

Yep, common problem and easy fix. I ran a bead of silicon under the lip where the cowl meets the glass and no more buzzzzzzzzzzz!

Thanks, guys. Great to be part of this forum.

$100 and 15 minutes to replace it if temp fix is not to your liking.

I've noticed that often times it depends on which way the wind is blowing. Mine was doing it, and when I turned to go another direction, the noise went away.

For you guys that used the double sided tape, did you put it on the entire length of trim piece or just spaced it out across the whole windshield?

After further research, I found this PI0766 http://www.sccorvettes.org/Portals/0...Windshield.pdf which is for a 2010-2013 Corvette. It's a GM document and has good picts and write up.

I just put a 2 inch piece of tape at what appeared to be the closest contact point to the windshield about 6 inches in from the right in my case.

I used that clear 3M tape with the red transfer film.

I have experienced this a few times during cold weather highway trips and it can really get to be annoying. Since it happens so rarely, I am on the fence about doing the GM recommended fix. I do keep a roll of duck tape handy and have only once had to place a six inch section over the cowl and windshield during a road trip. It looked tacky, but hey it worked as a temporary fix. I just removed it when I reached my destination.

I had a similar issue on my 2012 GS. Isolated the issue by applying tape along the lower right window molding where the molding meets the glass.

There is a GM Tech Bulletin which addresses this.

The local dealer repaired per the Bulletin, and problem fixed.
