1993 Chevy Suburban V8 Two Wheel Drive Automatic 150000 miles
I am trying to track down the problem with why I have no heater, I have replaced the thermostat, radiator, upper and lower hoses. I noticed that all the radiator hoses get hot and pressurized after driving except for the heater hose coming from the firewall that attaches to the heater core, this hose never feels hot as it should if hot water is traveling to the heater core for the heater. What could be causing my heater not to work? It is my understanding that if the heater core fails, it usually leaks water into the passenger compartment, is there another device that controls heater fucntions that I should look at?
