The blending of cool to hot is cable controlled so either the door the cable moves is stuck, or the cable is no good. I have not seen a lever on the control panel become stuck but There is a first for that because of its age, but I doubt it is anything but the cable or door in the heater box. Ok The cable is held in with a clip that is part of the cable near the blend door.
