Evap Freeze
Once the evap is frozen and occluded, no a/c setting will work. Ice has to melt so air can exchange its heat withe refrigerant in the evap.
I am puzzled as to why the current low temp setting of my evap would suddenly cause it to freeze; after 3 and 1/2 years of normal function. Just don't buy a software fix, especially one that will reduce cooling capacity. This car would consistently keep 38F at the center register. Could it be that the drain in the evap box has plugged? Long shot.
