hi I have been having various HVAC problems, first I was only getting Extremely hot air. then the actuator was replaced on both sides. it worked good for about a week or two. then I was getting cold air on the passenger side, and hot air on the driver side. actuator replaced again. now I cant get the fan to blow at the windshield. and it is blowing warm but not hot hot like last time. again it worked for a little over a week. I have checked all the fuses, disconnected the battery, and did the system recalibrate.
It has been repaired by automotive students. they said if it happened again I would have to take it to a dealer. I am not in a position to pay dealer prices. but I ran a diagnosis today after checking every thing.
I got codes B on the driver side and 10 on the passenger, then I got 82 on the driver side and 07 on the passenger side, the last code was 86 on the driver side and 07 on the passenger side.

To me its sounds like you have one defective actuator on the driver side which is sounds like you replaced, but the mode actuator is the one you want to replace here is the location so you can swap it out. The (B/10, 82/07, 86/07) are self-test display codes, not the actual Ford DTCs. Unfortunately, they aren't enough by themselves to identify the fault. A scan tool that can communicate with the HVAC module (such as FORScan or a professional scan tool) is needed to retrieve the actual codes (they'll look something like B1081, B2266, etc.). Here is a video to help

Here is the actuator I think you should replace which is on the drivers side. Let me know how it goes.
