There are two Auto buttons on the AC dash. One by the fans, the other by the vents outside inside air.

What do these do?

Why two Auto buttons?

To turn the AC on Auto why do you need two of these button controls.

Manual confused me.

Thanks

 

The one by the inside outside vents only controls whether it will recirculate inside air or take air from outside and it only works if the climate is on auto(the one by the fans is on)
