07 Silverado Passenger side window rattle

[jfpdlt01]

I'm pretty sure I'm not the only guy who notices any new rattle inside the cab of his truck. My passenger side window rattles (or something in the door). When you roll the window down about 1/4 of the way you can hear it really good on smooth pavement. I asked mechanics at dealership what they thought it was and they told me it was my bug deflector on my hood. Said the wind was vibrating it. Not convinced this was it I took bug deflector off and guess what, still does it. I've also taken door panel off and doesn't appear to be anything loose or broke on inside......any suggestions????

probably the windshield molding just like on the older trucks
