It is called a diverter box and you can buy them new and used (at times). There is a way to repair them if you can do a clever welding job. The door separates from the hinge pin because it is made of plastic with a bonded on rubber seal.
We rivet a piece of sheet metal to the door
and then weld the sheet metal to the hinge
pin and this makes a pretty permanent repair.
