I was having an issue where I would set my vent switch to full face and it was blowing full feet. Most of the settings were the same way. They would eventually work but it took awhile. Defrost works. AC/Heat work.

Took it to dealer and they stated that the blends doors are binding. They recommended replacing the doors by putting in a new heater box and actuator motor. Cost $1,100. WHAT???

Is it possible that I can attempt to fix this issue?

thanks

Try this site.
I'm about to do all this later this year.
Scroll onto the fodge link and you can then watch videos of how to diagnose which doors are failing and how to repair them.

If you can do it yourself, you can save a ton of money. I have replaced the heater core in my Mustang 3 time in the last 24yrs and have it down to a 4hr job now. It was about 7hrs.
That being said, just plan to make a day of it. Take your time and you should be able to repair it yourself with basic hand tools and a lot of patience. Might be helpful to take pictures as you disassemble things. It makes it easier to remember when putting it back together. Good luck
