    sounds like the water/coolant is not circulating properly.
    when last was the coolant system flushed?
    check the level too.
    may also be a pump on it's way out?
    some models have a valve in the inlet pipe to the heater matrix, make sure this is opening/functioning properly.

    Weak waterpump or poor circulation through the heater core
