I had my dash replaced under warranty for a "bubble" in it by the passenger airbag. Told the dealer to make sure that they really button it down since I had an occasional buzz/squeak as well. With the replaced dash the noises are twice as bad, especially when the summer months came.
Someone did a write-up on how to eliminate the most common dash squeaks... Should be on the site (did not have a chance to search for it yet).....
