I would think the only real test would be to disconnect the hoses under
the seat, then hook hoses to the heater and turn on the tap, for e water
through it. If the water flows, it's not the heater core. Next just
start back tracking. Hrd to say where the blockage might be.

You are sure the Heater valve is in the right position.??
