Disconnect both hoses that go to the heater core from either end, (the end at the heater core or the end at the water pump, manifold, radiator, etc.) using a garden hose, preferably with a hose repair end attached to plug into the hose or a short piece of hose cut off to connect to the heater core, run water in each direction through the heater core until water runs clear, then reverse direction of flow. Repeat as many times as necessary until flow is restored and water runs clean. Be sure to also flush the rest of the cooling system or debris from it will likely just clog up the heater core again.

How do you flush a 96 Ford Taurus heater core?
disconnect both the inlet and outlet hoses going through the firewall to the heater core... using a garden hose force water though one heater core hose until clear, then the other... do this several times until you have good flow of water in both directions... tips... try and use hot water through your garden hose... try to drain the entire cooling system and flush with water until clear and add a coolant flush additive and run engine for about 20 mins so the cleaner additive can break down some of the deposits... then drain and flush again.... if heater still does not work well.. then resort to disconnecting the heater core hoses and flushing and back flushing the heater core a few times... if all else fails, you might need to replace your heater core... good luck
