Vibration noise from ... the roof?!?

<<It wasn't even that windy>>??

Hehe , you were going 95mph.. Stick your head out the window and i think you'll notice it was a little windy.

f5fstop: Thanks very much. Will try that tomorrow. Are these TSBs available for free on the internet anywhere? I'm relying on the GM SI DVD and AllData, none of which are _that_ up2date.

SUT NEIL: No sunroof on this one I'm afraid, otherwise that'd have been my first stop

Dug: Mmm, true dat What I mean is I can normally hear/feel the wind bashing the car around when it really is windy. I couldn't this time.

That type of bulletin is not, since it is technically a preliminary information type and not a printed bulletin.

Just saw your post.

My suggestion is to pull back the roof sunshade (keep the clear plastic sunroof closed), go 95 mph, and have someone look out the sunroof. As goofy as it sounds, it's easy and sometimes works. I had a vibration at 80 mph. I had one of my sons look up through the clear plastic sunroof while I drove and it turned out the noise was one of the power cables for the lights on my GOBI roof rack. I use a couple of cable ties to solve the problem. Cost: Zero (I already had the ties in my garage).

Good luck,

could it be the seal on the windshield? i have the same issue and i was told it may mean the window needs to re-sealed , suposedly it is a "common" problem and covered under warranty at the "stealership"
