Heater only produces "lukewarm" heat. Have replaced the water pump, two thermostats. What could possibly be wrong?

Not producing the heat, the heater core is than likely plugged, on the passenger side you will see 2 hoses that lead into the heater core disconnect one of the hose or even both and flush it out with a garden hose
