well i have not worked on a 2002-2005 blend door, but if you have the actuator off i think your close. I would think you could take a wooden dowel and shape it like the shaft , put it into the door, and rotate and clamp. I have also heard of guys drilling a 1/8 inch hole in the duct and poking a welding rod or coat hanger thru the hole and pushing the door to one end and tape the rod in position... just some ideas.
