Hi Roy, here's a couple of things to check. While running and at operating temperature, look in the overflow container and see if you see bubbles. If you see bubbles, you head gasket is leaking. It's blowing hot air into the cooling system causing it to overheat and disrupting the water flow causing no hot water to flow through the heater core. Check to see if the the upper hose and lower radiator hoses are both warm. when it's at operating temp. You may also have a plugged heater core as well. Check the operation of the blend doors of you heater controls. You should be able to hear them open and close.
