So I pulled my ac control unit to replaced the burned out light bulbs and 2 weeks later I can't change air flow direction. I can live with it because it's stuck in the
forward direction (1st button). The only issue is no front defroster. I hear the
ac kick in when I push the defrost button but no change in airflow and nothing from the vent on top the dash near the glass.
I can still change the temperature.
I doubt the control unit is the problem. It actually worked once a day or so ago.
Should I be looking for a fuse or pull the blower assembly???
