A4 - Defrost in cold weather???

[Kris Hansen]

You have to put the defrost on, and let it run at full
blast. I never figrued out why they don't run the air
through the dryer, though it may actually do that
without the compressor when set to defrost. 

A4's have very loud defrost vents IMHO. Best thing to
do is keep the defroster vents active all the time,
and add floor or dash. When the fog gets heavy, let
'er rip, and send all the air to the defroster. Works
99% of the time in my Avant, which has even more glass
to take care of!
