Air Blower direction 2003 Explorer

[Les Willliams]

my 2003 explorer only blows air from the dash vents. When I switch it to floor or defrost I can "hear" it trying to switch but it will only blow our of the dash vents. I did not find any vaccum hoses off under the hood.

Sounds like either a blend door issue or an actuator issue.
