Difficulties with the HVAC control usually come down
to that heater control valve, which is in the engine
bay near the firewall attached to a plastic box
which holds the valve (controlling the coolant 
circulating back into the car). The valve lever on 
that thing usually corrodes with age and eventually 
(always in the winter) snaps off. See if you can lubricate 
it, but if it looks like crap, odds are it'll eventually 
snap soon at which point the cable will free up but
you'll be stuck with a hot or cold car.
