Usually, with a plugged heater core there will be a bit of heat but not very much..I've only seen a few so plugged that there was no heat. One way to tell is to (carefully) touch the heater hoses just where they go into the heater core. Both hoses should be about the same temperature. If not and the heater control valve is open - then the heater core being plugged is a very good possibility.
