Sunroof Rattle

[mplunk]

Tahoe has developed an annoying rattle in the sunroof right where the movable glass meets the fixed glass on the passenger side. I can replicate the noise by pushing up on the glass, and the noise disappears when the sunroof is vented or open. I've checked for debris or anything in between the two, cleaned the gasket, and it still hasn't gone away. Has anyone else experienced this and found a fix? I'll take it to the dealer to get it checked out eventually but wanted to see if it was something simple someone here had already experienced.
