Factory installed integral A/C is combined with the heater, the A/C controls are in the same panel as the heater controls.
Large evaporator case located at the right (passenger side) rear corner of the engine compartment.
1973/79 F100/350 & 1978/79 Bronco: Bolted to the backside of the A/C/Heater control panel is this:
D5TZ-19B888-A (replaced D3TZ-19B888-A) .. A/C Vacuum Control Selector Valve Assy - Includes the "kicker" switch that turns on the A/C (Motorcraft YH-285) / Obsolete ~ 100+ available NOS
All the vacuum hoses from the blend door motors and the heater water valve connect to this valve.
---------------------
D4AZ-18495-A (replaced D1AZ-18495-B) .. Vacuum Controlled Heater Water Valve - Use with factory installed integral A/C (Motorcraft YG-136) / Available from Ford.
Misc 1970's FoMoCo Passenger Cars // 1973/79 F100/350 // 1975/91 Econoline // 1978/79 Bronco // 1986 Taurus/Sable.
This valve is a notorious POS!! Gets stuck in the closed, open or partially open positions.
