Where is the heater core location for a Mazda millenia?

The heater core in a Mazda Millenia is located inside the vehicle's dashboard, specifically behind the center console. To access it, you typically need to remove the dashboard components, which can be a labor-intensive process. The heater core is connected to the engine's cooling system, allowing it to use hot coolant to warm the cabin air. Proper care should be taken when handling it, as coolant can leak if the core is damaged.
