Make, model and year vehicle please.
Seems to be an issue with the mode door. These are usually vacuumed controlled but more recently are controlled by actuator motors. Newer vehicles use an hvac control module to control these things. Like Tom said what year is this vehicle and when you adjust the temperature do you press a button that shows you the actual temperature or do you turn a knob
