What do you have to do to your AC if it is blowing cold air?

it should be blowing cold air(wish mine did)but really though you might try to adjust the warm air control i think we are on the same page i found out if you turn your control knob all the way counter clock wise to the coldest postition it closes the vent from the outside, the recyle should kick on and not allow outside air to come in even if the controler is turned off
