You may need to pull the battery cable to clear the memory codes.
Otherwise, the controller could have failed or something with a blend door. When the controller "sees" cool air it commands the blend door to change air vents.

check the plastic vacuum lines that control it.... many find the problem is the soft dry rubber that connects the plastic tubes has rotted and leaked.
colors for the tubes are yellow, red, white, and green, but vary from car to car.
They connect behind the control and go under hood/pass side near the firewall.
