Scotty, everything was fine before the blend door actuator stopped working. I had to turn the blend door by hand from ac to heat. I didn't unplug the blend door actuator . It's still hooked up . The actuator is set on cold air but the blend door is set on heat. Could the actuator still being plugged in be causing the problem? I didn't think to unplug it . This was my first time doing it. Luckly The airbag didn't blow up in my face though. lol
