The direction of the air is controlled by one stepping motor only, which rotates a "valve" which direct the airflow this that and any-way. If you are getting different air flows to the screen etc., then this is working. There is another motor that controls a second flap that directs air through the heater or not. These two control all the variations of heat/cold and direction. A Tech II should find the fault. -- Richard & Mary Sutherland-Smith 19 Webb Road, Wanganui New Zealand
