It didn't work, no change. I removed the blend door actuator and it's resistor inside was burnt out. Put new one on and checked the other two actuators temperature and recirculation and both were working with a 9v battery test. I made sure to keep them in their original position. I tried recalibrating again and the new blend door actuator moved to both max positions, then began to twitch back and forth.
