Whooshing noise through vents?

[clonzana]

Started to hear a whooshing noise through the vents, typically when driving 30mph plus. No noise when lower than this, or stationary. 
 

I know that my blower fan is a bit noisy, but this noise even occurs when the fan is off. It just sounds like wind noise coming straight through the vents. Any way to alleviate this?

Hi, 
This have happened to other members before and they found it was from the air vents flaps that been positioned almost in closed but not fully closed position and this is how the air goes through tiny openings and creates these. Issues. Check rotary switch at each vent on your dashboard and see if this is in your case too. 👍
