Loud high pitched whining noise coming from my heating vents when I accelerate. on 2001 Volkswagen Cabrio

It only occurs when I am going more than 35 mph. If I open the windows, the noise decreases slightly, but is still there. I am almost certain it is in the interior - not the engine. It started 3 days ago.

Side note:
Vent has always also made a small rustling noise when I have the main vents (over the center console) blower on foot. I have to toggle the drivers vent and the center console vent to make it not make any noise...

Anyone else experience this at all?
