    I want to stop outside air from getting in when I have recirculation on. Fumes, odors, climate air, still gets in.

    Can it be done?)

    It's done that way by design, they have to let a little outside air in even when recirc is on so you don't suffocate.

    At least it's that way for cars...

    He's right. I have a 2017 Volvo and the Manuel says the same thing.
