Re: no heat

Dick....I forgot to also ask you if the heat only functions when the AIR knob 
is pulled out (either part way for demist or all the way).  I thought that 
knob was only for outside air to freshen the car's interior.  I have been 
pulling the HEAT knob all the way out and turning on the blower full blast, 
and only this. Won't the AIR knob pull in cold outside air?  Thanks.
