Heater core. Mitsubishi's have poor heater core designs and they are a high fail item. I own a 2002 and have been trying to find a recall or either a class action lawsuit for them passing a known defective design. I own a 2002 and through my research I have found that if you own a Galant.....you are guaranteed to be without heat. By the way; the dealerships want $900 to replace their defective design. Sad part is the heat never goes out while the car is under warranty.
It's a much better idea to replace it. You can try the radiator flush, but no guarantee.

The heater valve actuator for a 2003 Mitsubishi Galant is typically located within the engine compartment, near the firewall, where the heater core is situated. It is often mounted on or near the heater control valve, which regulates the flow of coolant to the heater core. For easier access, you may need to remove certain components or covers in the engine bay. Always consult the vehicle's service manual for specific details and diagrams.
