Thanks in advance.
I have this same exact problem at this time. It happens if I leave the temperature setting around 68-70*F. It is an issue with the temperature blend door actuator. I haven't done the full diagnosis yet to confirm it but my local Ford dealer said these are commonly replaced. You can temporarily remedy this by entering the diagnostic procedure.
1. Set the temperature at 60*F
2. Simaltaineously press and hold the off and floor buttons then, while holding theses buttons mommentarily press the auto button. Release the Off and floor buttons.
3. You should see three dashes on the display.
4. After about a couple minutes codes will be displayed.
5. If you have code 24 or 25, it confirms a problem with the blend door.
A 24 is a hard fault, a 25 is a intermitent fault and should be cleared up.
6. To exit this mode, press the defrost button.
7. If you had code 25, turn the A/C on using auto or MAX A/C. The A/C should now work again. If you had code 24, try the procedure again and see if you get code 25. As long as you reset the temp back to 60*F before you shut the A/C off you will not encounter this problem. The blend door actuator is around $50 at the Ford dealer but I want mine to be a hard fault and fully diagnose this, more than likely it will be the actuator. Good Luck!!!
