Air vent recirculation
How do I modify my Expedition to allow for air vent recirculation on demand? Perhaps I can add a switch to shut off the vent on demand so that the outside air would not come inside, but all the vent dials would retain their ****ionality. Currently I only get recirculated air with Max AC, but I would like to manually choose air recirculation on all other vent settings.
