Ah-ha, I get it now. I was thinking the inside "fresh air" as I thought it was, worked like the drivers side - open = outside air. Not so, the top/cowl one closing means that becomes the "return" route for air in the cabin.
Got it - so in short, working as advertised because I have the cowl vent out right now. That is why I was getting outside air when it opened.
Thanks so much!
