Fig. 2: Identifying A/C-Heater Air Distribution Components
Courtesy of FORD MOTOR CO. OPERATION A/C-HEATER CONTROL PANEL The A/C-heater panel is located in the center of instrument panel above the radio. Air discharge outlets are located above, below, in center The lower slide lever is used to control temperature. Sliding lever from far left side (cool) to far right side (warm) increases interior THERMOSTATIC SWITCH With A/C system operating, thermostatic switch determines A/C compressor clutch on-time. Control is accomplished by a cable attached Switch is wired in series with A/C relay and Electronic Control Assembly (ECA). The ECA calculates compressor on-time based on A/C relay THERMOSTATIC EXPANSION VALVE The Thermostatic Expansion Valve (TXV) is a controlling device metering liquid refrigerant from high pressure line into evaporator. It also The high refrigerant pressure is reduced before entering evaporator by a ball valve within TXV. Depending on pressure applied to TXV Fig. 3 . |
