What to Do When the Car Has No Heater?

[BrooklynDella]

Solutions for a car with no heater: 1. Check the cold/hot air control to see if the air conditioning is set to the hot air mode; 2. Inspect the electronic fan thermostat switch; 3. Check the water temperature thermostat. The lack of heat in the vehicle's heating system can be attributed to two main causes: one is due to the engine cooling system, and the other is due to poor performance of the heating control mechanism. When the engine coolant temperature is high, the coolant flows through the heat exchanger in the heating system, exchanging heat with the air delivered by the blower. The heated air is then sent into the car through various vents by the blower. This system is simple and provides reliable heat without requiring additional fuel, as hot water is produced as long as the engine is running. However, it also has obvious drawbacks, such as the need for the engine coolant temperature to rise to the level of the large circulation before heating can be provided.
