Generally speaking, the warm air of the car comes from the waste heat utilization of the engine. Warm air is the most basic and effective heating facility in the car. It uses the circulating cooling system of the engine to generate heat, which is transferred to the cab through the blower. It belongs to heat reuse, so the power consumption of warm air is much lower than that of air conditioning, and the fuel consumption is very low. In winter, many car owners are afraid of the cold and still turn on the heating when the car is idling. ?
In hot summer, car air conditioning plays the biggest role. Southerners pay more attention to air conditioning and seldom use warm air, so many car owners may not know that the warm air valve is broken.
Symptoms of heater valve damage:
1. After the temperature rises, the wind coming out of the air outlet is still not hot.
2, can't turn off the warm air, the air outlet is still hot air after the temperature drops.
3. In the automatic mode of turning on the air conditioner, the temperature inside the car can't reach the constant temperature effect.
