I have a 2012 Edge LTD with the dual zone climate with 106k miles. I also had the issue of blowing hotter than hot air on the driver's side, and cold on the passenger's with the AC on Max. Thanks to this thread, I was able to try the recommendations here. I unplugged the green connector with the car off, plugged back in and turned car on. Turned on AC, still the same result. Next, turned car off, then unplugged connector, and started car. Turned AC on, no changes. Turned AC off, car is still running. Plugged the green connector back in, saw the rod move once I plugged it back in. Turned AC back on and it worked! We'll see how long it lasts. Thank you everyone!
