Default Passenger side air conditioning not blowing refrigerated air

2016 NX FSport
Passenger side air conditioning not blowing refrigerated air since last night. Just outside air, even at LO.
Driver side is normal.
Weird?
Appointment made for Tuesday at dealer.

Last year, the air quit coming out of the rear seat vent, ECU reset resolved.

Try to unplug the negative battery terminal for about 5 minute to reset the ecu. Hope this would work.

As for mine no personal settings were lost. The weird thing that if i set the air con temperature to over 25 celcius it will blow hot air to the passenger side but not driver side.

Folks need to realize one later thing. There is way too many computers and electronics in later cars. That feed off 12V and only electronic gremlins gods know, what will happen when you de power them.
It's much safer to locate and pull ECM fuse, you know.... That it has several, I have no doubt, but fuse is fuse. Pull all. No big deal. Particularly one that is related to climate control, as this is clearly hickup on climate unit operation, unless blender door servo went bad.

Took car to dealer this morning for air conditioning, added 30 month minor service (I have prepaid maintenance)
Dealer just called to say car was ready.....adviser said tech did software update. (no other details at this time).

Gotta love this dealer, I requested all wipers to be replaced for possible rainy season, since not changed out in 30 months.
Adviser said the wipers were still in good condition and they did not change.

Loaner 18 NX w/premium package very nice....goes over bumps better, more quiet, tighter brakes even though same miles as mine, Overall tighter feel than my FSport.
