The engine operates at normal temp, the heater fan motor moves air, the heater core hoses heat up to the touch when the engine reaches operating temp, I flushed out the heater core and it seems to be free from blockages. Why won't the heat get into the passenger cabin? Is there a gate that is not opening to allow air to pass over the heater core?

both hoses are hot? then its not restricted and it is narrowed down to ducting.

i would have to say that the blend door inside is not working, it forces the air through the heater core when hot is selected. could be a bad switch, sticking door or inoperate vaccum/electric motor for controling it.
