The little fan "encourages" the temperature sensor in the overhead to respond more quickly to temperature changes in the cabin. It [the fan] is unlikely to be directly connected to your problem.
As a start, remove the dome light assembly and check out the electrical connections to the temperature sensor. If one has broken or come off, the temperature sensor will not be able to talk to the CCU and the temperature dial will not work. The result will be the symptom you describe -- full heat with the dial set all the way to the click stop at the high end and no heat otherwise.
