Hi Kimala. If the heater is working but you have coolant leaking inside the cabin, then the heater core itself is probably good. However, there are multiple coolant lines that are hidden behind the dash that could have a small leak. It’s also possible that the heater control valve might be leaking as well. Without being there to inspect the vehicle personally, it’s hard to tell you exactly what repairs need to be completed.
