to the above, dammit, well I'll skip, that and save some time.

and... my wifes Wabbit blows very cold air on '3', er... I mean 'Hi'

>Well, I was under that impression. <re: vents to use>

The strategy here is that to keep the windshield clear, and sidewindows 
eventually, you want to pump ALL the hot air upwards. You'll get a 
circulation loop going, cold air returns, swirling around the backs of your 
ankles, pushed alnog by the rear heater also. If you heat the 
floormats+snow/slush too soon, the humidity level goes up and you fog the 
windows before they're warmed up enough to fight this. Many years in Euro 
cars, mostly Peugeots, has proven this to me. 
My Honda Civic was the s**ts for this, just a fogbox. It amazes me how many 
people drive with only a peephole scraped clear for the side mirror 
available. No lateral visibility at all. The van stays clear all around, as 
does the Wabbit using this approach. My $0.02, dismount_soapbox(now).   tim s.
