Answer
Sounds like you may have two separate problems. The lack of changing temperature is real common on Explorers as the blend door in the heater box tends to break. Usually the door will stay on the heat side because of where it breaks, many times the blend door motor also fails or overruns it's travel and must be replaced also.

The switching from vent to floor is another matter as those functions are vacuum controlled. The system will default to defrost if there is a loss of vacuum, so you probably have a control issue with the control head or a vacuum motor. There is no easy fix for either problem.

I have seen on the internet two temporary fixes for the door problem, but I don't recommend either one simply because they are band aids and not a repair.
