Feel both heater hoses going into the heater core with the engine running and hot and heater on.If one is hot and one is allot cooler then this indicates the heater core is restricted needing either flushed out or replaced.If both hoses are hot to the touch then this can indicate the temperature actuator on the heater box is faulty needing replaced.
