These problems have long been solved. Then, 20 years ago, it was all forgotten.

Behold my 1989 Bronco II:

    ----------[++]-----------------------------------
    MAX A/C   PANEL  PNL/FLR  FLOOR  FLR/DEF  DEFROST

    -----------------[++]----------------------------
    COOL                                         WARM

    OFF * * * HI

    PUSH FOR A/C
It has two sliders with positions as labeled above, then a rotating knob with 5 detented positions for the fan, and the label PUSH FOR A/C. The COOL to WARM slider is also color coded blue fading to red.

Turning on the headlights lights the display.

No manual is needed to fully operate it. I never even had the manual for that car. The knob and sliders are trivial, tactile, and visual. There are no modes.

It's near perfection in user interface design.

And then, the "AUTO" button was invented.
