Ok, well this only happens when i go 70+ MPH. There is this wierd sounding raddling noise and it sounds like its comming form the defrost front vent. (not when the vent is on or anything, just everyday). and i have hit the dash and everything... its really annoying... what is it?

 

My buddy had a simliar problem in a Grand Prix. Got a real loud almost constant rattle when he busted 70mph. One day I was riding with him and it was driving me NUTS! I rolled down the window and felt around to find the rubber windshield trim had popped out of the top. When you were stopped it would lay right over where it belonged so you wouldn't even noticebut at speed it would stretch out and rap against the roof.

God bless,
