I don't believe this holds true for automotive systems. On my old
Pontiac the A/C was directly tied to the defroster setting--switch the
system to defrost, and the A/C was activated. Good way to keep the
compressor oils circulating to keep the seals lubricated, in addition to
removing condensation. Worked at any temp, as I recall, and I move
around NY/New England.

I'll confirm this on my new 94 Civic in a few days, as it has now gotten
cold enough around here to check. Disabling it below 40 degrees would be
idiocy--it's the only way to remove condensation effectively. It is
true, however, that many room A/Cs don't function when the outside temp
is "too low"--which occasionally annoys me.
