There is either an access door in the glove box(used to primarily access the passenger airbag connector), or you need to remove the glove box. Behind that is a linkage rod for th blend door. Check that the rod is connected to the actuator arm, see if it moves when the system is commanded hot/cold. Disconnect the rod and manually move it, observe the change out the vents.
