Its a 5 hour job or so to replace the heater core. The heater radiator/core is behind the dash. If it is leaking it needs to be replaced or by passed by joining the two hoses at the firewall in the engine compartment together. If the heater core is plugged with debris you could try flushing the heater core by using a garden hoes and opening the heater valve fully, try flushing water in both directions.
