When you have been using the HVAC and turn it off, makes sure the system has not defaulted back to recirc mode.
Otherwise the windows will misty up in only a few minutes !.
In the bottom corner of the HVAC screen, you will see the symbol of an arrow turning back on itself, when this is displayed you are in recirc mode.
Each press will cycle through the three options.
Recirc on ( back arrow ) recirc off ( arrow showing air being drawn in from outside ) and the “A” symbol for Auto mode !.
It was similar on the Gen 1 model but you had a recirc button with an orange light, to tell you when it was on !.
