Blend doors can be a real pain. Sounds like your door is either broken or something is caught in there causing it to jam. I would remove the actuator and operate the door by hand and then see if you can tell what's up?
Sometimes you can use an inspection mirror and flashlight to look inside the vents, sometimes not.
you might have to remove the blower motor or even loosen/remove the dash depending on the vehicle. I've done a bunch of them in big trucks and tractors and econoline vans.
