With the aircon off and with the drivers window open just a bit, I have a wind noise coming from vent under dash.( whistling noise)

If I close the window will go away.

If I turn aircon on, without AC, have to turn halfway the speed fan for the noise to go away. ( with window a bit down)

If I turn AC on will also go away.

If I turn on recirculation it will also go away onced turned halfway speed fan.

Its buging me, it did not do this, could be the cabin filter that needs replacement?

OMG no replies

Just rub it in, you´re driving around all happy with your VRS´S and haven´t notice this.

Shame on you

I don't think its a fault... its just wind noise and air turbulence around the nozzles.. different fan speeds will mask it when the fan is moving more air through the ducts which becomes stronger than the air turbulence... I do notice it a bit when the radio is off but the engine and exhaust noises are more entertaining..
