The shaft that connects the blend door actuator to the blend door inside the Evaporator Core Assembly housing is broken off?

(As found on my used Edge). Is there a drawing out there somewhere of what the inside of the Evaporator core housing (CT4Z-19B555-G) is constructed? I'm wondering if I have to replace the whole thing just for a single broken shaft or if I will be able to repair or replace just the door itself. I can't seem to find any exploded drawings or diagrams of the actual blend doors themselves.

Unfortunately, the entire case has to come out and come apart to repair or replace the blend door. The service info we have doesn't show the breakdown of the case, but I believe that one splits along a vertical seam.
