I am going to second the recommendation of @RatRacer
. Based on what I think I have seen from pictures, I think the blend door is totally different between the manual and auto- climate controls, I suspect there are several extra sensors involved, etc. For instance, I don't think there is any requirement for a humidity sensor on the manual, but the auto requires one or more.
