Hmmm... I'll have to think about that one....
It doesn't seem to change WHERE the air is coming from, like from vent to
defrost, just the temperature of the air...
It can bee cool outside and the air through the vents can be changing from
hot
to cool by itself..
I'm starting to wonder if there's a way to just jam the doors or something
to
keep it on "cool", no matter what the dial/control is turned to??
