My wife’s 2018 expedition max limited has started to have this problem with the fan being on high and not blowing at all or very little. The blower is still working but no air out vents. I bought a new blower motor resistor but can’t find it for the life of me. I’m really needing someone to point in the right direction of this car. We have had nothing but problems for this past year. We love the car for the size for the kids but it’s starting to become a pain.
