Has anyone ever tackled this repair, changing out the actual air directional box inside the dash? I thought my blend door was broken but it's actually the lever on this box that is directed by the vacuum cylinder. I'm guessing this will be a major, dash pull, type repair?

I have had that item in my saved shopping cart for several years now... I have the door wedged closed with a strip of scrap wood. I read it is just as you described, a very involved job.
