Replaced the heater control valve in my 96 ford ranger because it wouldn't blow hot air. Once the new valve got put in the hot air blew just fine. Recently this morning I tried to turn on the hot air and nothing came on. The part was under warranty and I got a new one to see if that would work. Nothing happened and there is no suction to the heater control valve which makes it change to blow hot. What would be the problem?
All you have is the vacuum switch on the heater control switch assembly and the vacuum hoses from the engine and to the valve. If any other mode motors work in the dash, the vacuum supply has to be good. That leaves the switch and hose going to the valve.
