Depending on how yor car is equipped manual HVAC system or automatic climate control system...but it sounds as if the blend door motor or the duct it works could be cracked. The electronic controled system has several air door motors. Sometimes the blend door motor can be accesed by removeing glove box....others may require removal of dash panel. Most of the time this repair requires a experienced technician to diagnose and repair.
