AI caption · Photo 321 of 529

This document is an exploded parts diagram showing the A/C evaporator assembly and its mounting to the dash panel, uploaded as part of a Ford Bronco reference album. The illustration identifies the A/C evaporator assembly (part 18C424), the evaporator rear housing assembly (19A583), the air inlet duct (18C624), and the duct assembly (18A442). It also shows the outside-recirc door vacuum motor with its white vacuum hose, a vacuum line with a green and white stripe, and the de-icing switch mounted on the evaporator case. Fasteners are called out throughout: screws (including screw 55915-S2, 3 required, noted in two locations at the air inlet duct and duct assembly), nuts securing the housing studs through the dash panel, and caps covering fastener locations. A reader can learn the relative positions of the evaporator housing components on the engine-compartment side of the dash panel, which Ford basic part numbers correspond to each component, and where and how many fasteners are used to attach the air inlet duct and duct assembly. The diagram contains no year, model, or engine applicability text of its own.
