No heat, has replaced thermostat, radiator and flushed system. Filled system back up let run to temperature. Very little heat. Top hose hot and both heater hoses are hot and lower radiator hose and thermostat housing cold. Any other ideas on what we can do? Thanks Mark Engine not over heating could it possibly be the water pump.

Is there a heater control valve inline on one of the heater hoses? If so, be sure it is working, if not could be a blend door problem under the dash. Look for what door operates when hot/cold is selected and be sure it is moving all the way. Get back with what you find
