Heater core functionality
Before we diagnose the trouble, it'southward important to understand how it all works. The heater core may be a office of the air-conditioning system, but it relies on using hot circulating engine coolant to deliver heated air into the motel or for defogging.
The cadre itself is like a tiny radiator. Similarly, it has tubes that coolant passes through and fins, where air passes across. Information technology uses the estrus from the coolant to warm the air that volition then be blown into the motel of the machine.
Some vehicle systems take a valve that regulates when coolant should flow to the heater cadre. Others have coolant circulating by it constantly and simply open up a door or flap to allow airflow into the cabin. The air is pushed into the motel past the blower motor, which activates when the air conditioning system turns on.
If heating is desired, the air is directed through the heater cadre. If cooling is desired, the air is directed through the evaporator instead which is cooled by refrigerant.
