Heat wont swtich

2011 F250 6.7 Heat will only come out of the dash vents it will not come out the defrost or on the floor. Its the single zone system and not auto.


If I turn it off, and hit defrost it acts like it wants to go, then just goes straight to the vents.


I don't hear anything trapped down in there.
