I'm thinking to myself max air sure doesn't blow very hard, and it sounds kinda like a vacuum leak when selected. (Kinda loud for a vacuum leak, but that's what it sounds like). I remove the glove compartment door (ultimately unnecessary) start poking around and find a small plastic bag sucked up into the interior (max air) inlet pipe. She blows much harder now. Lol
