Weird noise (rattle like)

[hulk311]

I noticed a very weird noise in my 4Runnner, it seems to be coming from the middle two vents in the center console or somewhere there. And it ONLY can be heard when driving on the highway at 55mph+. At first I thought it was just loose coins or a loose pen, etc. somewhere in the glove compartment box or ashtray but it wasn't.

Does anyone have any idea what it might be and why it only makes noise when driving at highway speeds?

Probably stupid of me to suggest, but did you check to see if there is an old leaf stuck in your vents? My dad had one stuck in one of the side vents of his BMW and it made a weird noise at higher speeds.
