1979 Ford Bronco/F100-F350 Heater & A/C System Component Location Diagram

This page (page 39) is from a Ford truck electrical/vacuum reference covering the Heater/Air Conditioning System and Deluxe Heater. It addresses two subsystems: the blower system (electrical) and the controls system (vacuum). The page consists of an isometric line drawing of a Ford pickup truck with the HVAC components drawn in red at their approximate installed locations, connected by dashed lines representing vacuum/electrical routing. Labeled components include the A/C heater function control (vacuum portion), the A/C heater function control switch with blower switch, the A/C heat vacuum motor, the blower motor, the outside/recirculate vacuum motor, the heater water valve vacuum motor, the blower motor resistor, the A/C defrost vacuum motor, the fuse block, and the A/C clutch. From this diagram a reader can learn where each heater/air-conditioning electrical and vacuum component is located in the vehicle, most components cluster on or behind the firewall and dash area, with the A/C clutch at the front of the engine compartment. The page is a component-location overview rather than a wiring schematic; no wire colors, fuse ratings, or part numbers are shown. It belongs to a multi-page set uploaded as "1979 Bronco F100 through F350."
