I have the same issue on my 2010 Fusion. Taken it to a mechanic 4 times so far and they have not been able to fix it. They did an AC check and re-charged the freon the first time; 2nd time they couldn't find anything wrong becuase they couldn't duplicate the issue; 3rd time I left it running "hot" and took it back and made them check it out, they figured out the blend door is the problem and replaced the motor that controls it. Although this helped for a couple weeks, the AC is now running hot again; took it back a 4th time and they couldn't duplicate the issue (again). My husband suggested they replace the control module, but since they couldn't duplicate the issue while they had the car (even though they witnessed it was blowing hot before I turned the car off), they wouldn't do anything. Day to day I don't know if I'm going to have AC or not. Yesterday the AC worked perfectly. Today it was blowing hot again. I think I just want a new car.
