2005 Ford Explorer defroster doesn’t work

My Ford Explorer (2005) defroster doesn’t work. I have tried all settings and I can’t get any warm air to my windshield. In rainy/cold weather here in Reno the inside of my windshield fogs over to the point that I can’t safely drive. The heater seems to be working fine. Is there an easy fix?

Likely broken blend door actuator. Easy fix? All is relative, but should not be too bad.
