When I purchased my '12 Coupe, my buddy purchased a '12 GS (same time, same dealer, and same color.)

He's now is experiencing the dreaded cowl howl @ 70 MPH. I've read several posts on solutions to fix this issue but have not seen any photos that points-out the exact location of the problem. He's headed to Las Vegas in a few days and would like to make a temporary fix before he takes it to the dealer.

So that being said, can someone point me to some pictures/posts of the area in-question? (I have searched with zero luck)

Thanks....

No pictures but this describes it well:



Obviously the tape doesn't "have to be" blue () but I suggest the wide stuff whatever color he uses.

Just found this while looking around. A different approach he may want to try:

Models:

2010-2013 Chevrolet Corvette

Condition/Concern


Some customers may comment on a buzz type noise coming from the lower right side of the windshield while driving at highway speeds. The noise will be greatly reduced when the HVAC is placed in the “Recirculate” mode and will return when the system is placed back into the “Fresh Air” mode.

This condition may be caused by the air inlet grille panel (cowl trim panel) fluttering against the windshield glass.

Recommendation/Instructions


Use the following steps to diagnose and repair the condition.




1.

Apply masking tape over the cowl trim panel to windshield gap. Drive the vehicle to verify the condition is eliminated. If so, proceed with the next step.





2.

Remove the rear hood seal. Refer to Hood Rear Seal Replacement in SI. Only remove the right side of the seal. Complete removal is not required.








3.

Remove the right air inlet grille panel screw.








4.

Remove the two right side cowl trim panel clips.








5.

Disengage the two hooks that retain the cowl trim panel to the windshield glass on the right side. Lift the right side of the panel as shown to expose the two right clips.








6.

Cut four 25 mm (1.0 in) long sections of *Kent Industries Butyl Rubber Windshield Tape, Part # P20230 or the equivalent, as shown.











7.

Install the material on the two right side hooks as shown.







Ensure the material wraps around the end of the hook.





8.

Reinstall the cowl trim panel and ensure the hooks are fastened under the edge of the glass.





9.

Reinstall the two right side cowl trim panel clips.





10.

Reinstall the right air inlet grille panel screw.


Tighten
Tighten the screw to 3 N·m (27 lb in).





11.

Reinstall the rear hood seal. Refer to Hood Rear Seal Replacement in SI.

ADIBELC6, thx for service bulletin post. Will take my C6 GS to dealer and have them charge their time to the warranty code listed. I like to do my own repairs - but not for crazy stuff like this
