Well, the obvious question is... Is the heater core good?

Are all hoses routed correctly?

has the heater core been bypassed?

Usually when this happens the heater core needs backflushed. They get clogged full of junk.

Take the hoses off and use a water hose that you can hose clamp onto the heater core line. Flush it out backwards. There maybe other ways but thats how I would do it in a pinch.
