^Me too... My M35 has it but not the QX
AC is not always needed when on recirculate...
If you hit the climate button, you can go into a screen where you can turn the AC on and off. I am not sure if it will stay in recirculate mode if you turn the AC off, but you can give it a shot.
Yes, the windows will fog up if you have recirculate running w/out AC.Is there a reason you don't want the AC on or why you are recirculating the air?
Does not happen always though. Mostly an issue in winters. I wish Infiniti let drivers decide for themselves when to use the feature like all other car makers do.Yes, the windows will fog up if you have recirculate running w/out AC.
