dbrebell,
these are quite plausible statements, but it's hard to imagine how climate
control would work if some (one or more) parameters overridden ? e.g. how
anything would function if fan speed is fixed at nearly 0 ?

by the way, i have the same car, and i am confused with mode "auto" itself.
when I turn the car on i have only temp values displayed, neither "auto"
indicator is displayed nor "ac on/off","mode","fan". based on your idea it's
already auto mode because no overridden values are on. now, when i press
button "auto" indicator "auto" is displayed, so it means I have overridden
what ....."auto" i had by default ????
