Footwell vent closed (normal)----------27mV........................16mV
Footwell vent open (modified)----------50mV .......................45mV
There is a greater airflow at the vents with the outside air intakes open, but that air, in the A/C mode, is warm, unconditioned and could result in a higher cockpit vent temperature.Note – Higher voltage (mV) equals greater air flow
