How does the heater work in a car?
As the engine reaches the proper operating temperature, the thermostat will allow coolant to circulate through the engine to “gather up” excess heat and move it to the radiator. The coolant also circulates to the heater core, which can distribute the warm air to the cabin.

There are a few potential culprits for why your car engine coolant may not be heating up: Coolant Level – The first think to check is the coolant level!
What can cause a car heater to not work?
– Low coolant – A blockage in the heater core – A stuck blend door – A stuck heater valve – A bad switch or linkage
What to do if car heater is not working?
Check the heater core temperature. Lift the hood and check the temperature around where the heater core hoses enter the heater core box. The safest way to do this is with a non-contact infrared thermometer. If one hose is the same temperature as the coolant and the other hose is cold, there may be a blockage in the heater core.
