When I am driving at highway speeds, say 60 mph and up and I open my sun roof, the wind deflector vibrates like crazy, so bad that it vibrates my rear view mirror and the noise is deafening. I am refering to the lexan deflector, not the metal strip that pops up when opened.
Does anybody else's do this? And if so did you fix it? I just drove to Fort Sill, Ok, about 7 hours from home and tried to drive with it open, but that didnt last.

A lot of vehicles have that problem. My sisters Jetta and my aunt's Beetle both had that problem. You open it and it sounds like there is a helicopter overhead.

 

Lower the cargo window an inch to reduce the pressure inside the cabin.

 

it will also make that noise if you lower just the rear windows down to about half way..... off topic sorry...

 

I had the cargo window, and the rear windows down, and it still made the noise. I guess I wont drive with it open on the highway.

Thanks- Mat
