    I am going to guess it could be the door that changes the vent settings is stuck/broken or the switch that changes the settings could be broken.
    If it was just blowing out of the defrost vents I would suggest a possible vacuum leak.
    The vents wouldn't change on my XJ and since it was stuck on defrost I thought it was a vacuum leak but after not finding any I swapped in a used switch and was good to go.
