Hmmmm, when I installed mine the mileage sucked for the first couple of
weeks, but then returned to normal or possibly increased a couple of tenths.
(Normal being 17.5-18MPG mixed highway/city, on a '95 5.2.)
It's very possible that the sucky mileage was due to PCM self-adjustment,
but I think it had a lot more to do with my new desire to mash that pedal
and listen to the new sucking sound. ;)

That's by design. Defroster usually works better with dry air than moist
air. It is possible to disable this 'feature' on at least the pre-'97s,
but you'll have to look at the archives to find the procedure (it involved
tearing apart the mechanical/vacuum climate 'brain' and pulling some sort
of electrical bridge between the A/C clutch and defrost button).

The best way to keep an automotive A/C system running well is to run the
compressor for at least 10 minutes at least once per week. That includes
the middle of winter. The compressor, seals and hoses all benefit greatly
from normal oil circulation during operation. Many leaks can be traced to
shrinking seals that probably just dried out due to lack of operation.
