My expereince with this noise, if it's the same one you describe, is it happens with a strong headwind or crosswind, but not every time.  Playing with the slider vents on the lower front door panels makes my flapping noise go away.

Subject: Vent flapper noise?

Hi volks,

This weekend I noticed a vibration noise up front that I've never had.  It
only occurs at about 50 and higher speeds and sounds like its in the dash
or behind the grill, possibly.  I've driven me van plenty of times at that
speed but have never heard it before.  I replaced the dash a few weeks ago
but am sure I've had it to that speed since as well.  I may have caused it
while adjusting the vents.  Before I noticed the sound I felt warm air
blowing thru the two dash vents (defoggers) on the dash top near the
windshield and down on me feet so tried to stop the warm air flow.  I'm sure
this warm air has been flowing all spring but it's just now warm enough to
bother me.

Does anyone know of any kind of vent flapper noise at these speeds?

Thanks!
