That code means the blend door failure which could be the door, actuator or something else because it's auto temp control. It may be another sensor causing the actuator to ask for heat instead of cool. In future mention if it is auto temp control or not. Do the test in the 2 pics it will tell you if it is the body module or blend door actuator.
