Ford Manual HVAC Airflow & Control Knob Diagram (AM2264-A) - Heater/AC Schematic

This document is a Ford reference schematic (illustration number AM2264-A) depicting the airflow and control layout of a manual heater/air-conditioning (HVAC) system. The upper portion is a cutaway airflow diagram showing hatched arrows tracing air paths through the heater/A-C plenum assembly and ducting, illustrating how air is routed to the instrument panel (dash) registers, windshield defroster outlets, and floor ducts. The lower portion shows the three rotary knobs of the climate control head: a blower fan speed knob marked from LO to HI, a temperature blend knob marked COOL to WARM, and a function (mode) selector knob with positions including MAX A/C, A/C, OFF, and floor/panel/defrost combinations such as PANEL & FLOOR, FLOOR, FLOOR & DEF, and DEF. A reader can learn how the manual HVAC controls correspond to the air distribution paths inside the plenum, useful for diagnosing blend door, mode door, or airflow problems. The document carries no year, model, or engine designation of its own; it was uploaded to a 2007 Ford Mustang gallery, but the surrounding album contents suggest it belongs to a set of Ford truck (F-150 era) reference diagrams. The image is a small, low-resolution GIF, so fine label text is only partially legible.
