1974 Ford Bronco Heater Assembly Exploded Diagram - Defroster Hoses & Blower

This document is an unlabeled exploded-view parts illustration (Copyright FoMoCo) of a heater and defroster assembly, uploaded to a 1974 Ford Bronco gallery as 'heater.jpg'. The only text callout identifies the 'Defroster Hoses', two flexible corrugated ducts shown at the upper left connecting to outlets on top of the heater plenum. The drawing depicts the complete heater box assembly in exploded form: the main heater housing with defroster outlets, a round blower motor with impeller/fan wheel and its mounting plate, gasket and seal rings for the blower opening, the heater core with surrounding foam sealing strips, various rectangular gaskets and seals, an access/mounting panel with attaching hardware, and the firewall or cowl area where the assembly mounts. No part numbers, torque specifications, quantities, or model-year applicability are printed on the diagram. A reader can learn the physical arrangement and assembly order of the heater components, how the blower motor, heater core, seals, and defroster hoses fit together in the housing, which is useful when disassembling or rebuilding the heater box, but must consult other sources for part numbers and fastener specs.
