I just recently perchased my car a couple of days ago and when I baught it both the air conditioning and the heat worked and as of yesterday they both stopped working all together. The fan is working just fine and all the controls but its just blowing air. Could somebody please help me on what this might be?

Suspect the blend door actuator, located on top of evaporator assembly, controls blend door movement according to command from control panel. An electric motor moves blend door. A separate potentiometer feeds blend door position information to control panel.
