vents question.
is there any way to turn off outside air when heater/ac/defroster is not running on a 21 F150?
i know using the recirculate air button when running cuts off outsie air, but with system turned off, recirculate air also shuts off letting outside air through the vents.

Not sure if I understand the question but on mine with the hvac turned off no air comes in. I use the power button on the hvac panel to turn it off, I use this in the winter when I pull out of the heated garage to not pump cold air into truck while engine heats up. Not sure if this would be the case with the truck turned off though.

You have me wondering if different trim levels would affect how that works. My 23 works that way, so did the 14 before it and a 17 Expedition we had for a while. Not that any of that does you any good.
