help weird noise coming from center vents
 

Hi,
I have '01.5 A4 2.8 with Bose and 53K miles and I am starting to hear this
noise coming from the center vents when I turn on the AC. It all started
happening after Isabell hit the East coast last week.
The noise gets louder when I turn up the fan speed, and dies down when I
bring it down. I only hear it when the inside temperature is higher than
what the climate control is set at.
The noise is kinda like when you put like a twig or something in a pedestal
fan or something like that..

Please any help would be appreciated..

Thanks

Long live the Quattro!!!
