Why does my 1991 Lincoln Town Car's AC and heater work at either full blast or not at all?
if i put the dial all the way up it blasts me but just touching it downwards results in no air at all.

Answer 1 :
sounds like the blower motor resister,but without proper diag this is not for sure. The resister or (blower speed con troll ) is in the evap case on the passenger side under the hood. Wish i had more info .
Answer 2 :
blower motor resistor is bad. full blast bypasses the resistor. cheap part easy to replace. i believe the resistor on that year is located in the plenum behind the glove box.
Answer 3 :
well don't touch the fan switch don't put it all the way to blast let the auto system take care of that and see what happens
