Air Blowing from Vents

I have had my truck about a month now (2018 DCLB). I have noticed with all of the climate controls turned to off I still have air coming through the air vents on the dash. It is faint air almost like the lowest blower setting.

The only way I can get the air to stop blowing is hit the cabin air recycle button. Then it will shut off. It is almost like a valve for the outside air isn't closing all of the way when I turn the knob to off unless I hit the air recycle button.

Has anyone else experienced this?

 

Maybe to make sure the vents dry out from condensation build up?

 

Ok thanks. Just wanted to make sure I didn't have a sticking valve from the factory

 

Same in every car I’ve owned

 

Yep ... that’s exactly how mine is.

 

That's how mine is. I just typically close them if it's bothering me.

 

that is Normal my 2018 does the same and I love it fresh air all the time (except when driving by the sewage treatment plant gasp!) just hit the recycle button for cabin air
