This happened a while back on the wife's 2012 edge SEL model. I unplugged the actuator motor and plugged it back in and it went back to the cold setting. I'm pretty sure it will need replaced and the pass side just got stuck on heat so I unplugged it like I did the drivers side and its now back to blowing cold. This time I watched the door move while I changed the temp but it doesn't look like it blends very well meaning, its either full on AC or full on heat. So now I am researching changing both actuators.
