[Shotimes] Where do you set your EATC to?

[Tommy]

I was reading the ownwer's manual in my '95 yesterday and it stated that it is
best to leave the EATC in the "Automatic" mode all the time for winter/summer.
I don't do this becasue I think the compressor runs all the time in the
"Automatic" mode even in the winter. In the winter I usually wait until the
engine warms up and either put it on "Floor" or "Vent" thinking the compressor
is not running.
Is this true? Is the compressor running @ temperatures below 50: F?
Thanks.
