Why won't my 1995 ford ranger ac blow through the vents?

I have a 1995 Ford Ranger 2.3 and the ac won't blow through the vents. It blows through the top defroster, and on the floor. I changed the door actuator, but still is stuck. The fan works on all ranges low to high.

It may be the blend door itself.Drop the glove box & have a look inside.
Also suggest going to the Ford Ranger forums for advise from guys you have actually dealt with this problem.
