Ford F-100–F-350 & Bronco A/C Heater Register and Duct Assembly Diagrams

This document is a set of three exploded parts illustrations covering the heater/air conditioning register (vent) and duct assemblies for Ford F-100 through F-350 trucks and the Bronco. The top illustration shows the right register and duct, identifying the right register, the relay assembly (with a reference to View A), the duct assembly, the plenum chamber, and the portion of the instrument panel the register mounts into. An inset labeled View A details the relay assembly mounting, showing the relay assembly, wiring assembly (part reference 19A885), and mounting screw. The middle illustration shows the left register and duct, calling out the plenum chamber, duct assembly, part of the instrument panel, and left register. The bottom illustration shows the center register and duct, with callouts for the plenum chamber, duct assembly (including a flexible/bellows duct), part of the instrument panel, and center register. A reader can learn how the dash air registers connect to the plenum chamber via ducts, where the relay assembly and its wiring mount behind the right register, and the general orientation of these HVAC components behind the instrument panel. No torque values, fastener sizes, or model years are stated in the document itself.
