I've checked the air mix door actuator under the glove compartment and it still works. Moves back and forth no problem. What else could be causing the blockage of cooled air to the front ac vents?

SOURCE: AC not blowing out top vents

check the hose are not obstructed or broken.

SOURCE: Problem:

Problem is most likely in the electronic blend door motor or the door itself has broken.
To access the electronic temperature blend door actuator remove cassette storage box or center shelf unit, if equipped.
Remove instrument panel ash receptacle by depressing service lever. Disconnect electrical harness connector from A/C electronic door actuator motor.
Remove three retaining screws.
Carefully pull A/C electronic door actuator motor outward and off A/C evaporator housing assembly.Make sure the door it self is not cracked where the actuator hooks to it and that it will move.
Here ia a link to a pick of what you are looking at.

There is a actuator on the right side of your leg while sitting in the drivers seat under the dash. It has a plastic rod for actuation manually actuate this diverter and should be the problem.
