Probably right, but when I make a climate control change, it reverts back the first time, but it seems to "stick" the second time I make the same change.

So, try turning off the AC/fan BEFORE turning off the car, and see if the car "remembers" the setting after 2 or 3 consecutive tries when shutting down.

Exactly right, mine stayed off after the 3rd consecutive try. Although sometimes it does revert back and turn on (on the lowest setting) when I start up the car.
