Air recirculation noise

[turtuv]

Hi guys, i would like to understand one thing: when i press the "air recirculation"'s button, have i to ear a noise of the fan? Because i don't ear any noise, when i use the reverse gear neither. I ear a noise only when i push the windshield defrosting button.

Yes this is normal, you can reduce the power to attenuate it.
You should only use recirculating when it stinks or in case of smoke. The air not renewed will increase the humidity inside the car and you will not be able to see anything through the windshield

Yes, i know that, what i want to know is why i don't ear any increase of noise when i pressa the button. I don't know if my air recirculation's system is broken
