Hi
We are getting used to our newly acquired 2019 Express, but can not find how to recirculate air or cut off the air intake when we are on dusty roads. Is this not possible? How do folks deal with dusty roads? Thanks

 

it should be explained in detail in the owner's manual.
On my van it's the MAX A/C setting. You can physically hear the door opening, and then the blower noise inside the cabin.
