underneath the dashthere's a black box that blows air out by your feet inside there is a small door like flap that cuts off air conditioning for heating controlled by your heating or cooling switch a lot of times this crap will break since it is plastic this will cause air temperature to stay the same no matter if you're on hot or cold it may be stuck closing off the heater pathway
