03- Z71 - Sunroof

[Greggcellent]

I have an 03 Avy with a factory sunroof . When I open the sunroof and leave all the windows up and drive down the highway I get this terrible noise inside the vehicle . I know its pressure building up inside the vehicle . The only way to stop it is to let one of the windows down a little . Does anybody else have this problem ? If so what did you do to correct the problem . Thought about one of those sunroof visors attachments ,,,but dont know if they work or not .

I have the same problem. I believe the springs that push up the factory defelctor are to weak. If you push up on it the noise goes away. Next time I am at the dealer I am going to see about getting them replaced.

I have installed a benevento deflector on mine and love it. Wished I would have done it a year ago. You can have the roof open, radio on at a moderate level and still carry on a conversation. It has some adjustable flaps that allow as much air flow in as you want, and is held on with clips that can be removed for cleaning and waxing under it.
