Why does AC blow hot after blend door and HVAC Control center were both replaced
What is your question?
Yesterday (for the 2nd time) I replaced the Blend Door Actuator & the HVAC Control Module. The evap temp sensor cannot be the culprit as it controls the compressor which is working perfectly. This vehicle is a 2012 Ford Fusion.
After the blend door actuator was replaced the first time, it worked for about a month, then it failed again, and then the HVAC control module and the blend door actuator were both replaced, but after about 3 weeks it failed again, so I rigged up a coat hanger to manually open and close the blend door. It stayed that way for about 18 months. Yesterday I decided to replace both the HVAC control module and the blend door actuator again, and now when the vehicle is started up, it cycles cold, then warm, then cold and then goes hot and stays hot. Is there another control for the blend door actuator in the system that I am overlooking. I cannot believe that three HVAC controls and 2 blend doors have failed.
What makes this problem better or worse?
Doesn't work after replacing both parts
How long has your 2012 Ford Fusion had this problem?

Do you know that the air conditioning system is producing cold air?
If it is, and it remains a problem with blend control, I would suspect an issue with the plenum itself. The actuators may be fine, but the door it operates could be stripped where it hooks up. Or it could be broken. It concerns me a bit that a hanger was used for a time; can't imagine this would be good for the plastic components.
