The water temperature in my car is high, but the warm air is not too hot. What happened?
1. After the cold machine is started, the temperature of the automobile engine is low. At this time, the warm air will not be hot. This is a normal situation and can be solved after the engine is warmed up.
2. Check whether the vehicle refrigerant is sufficient. If it is not enough, the heater will not get enough heat. In this case, we can only solve the problem by adding antifreeze.
3. The thermostat is opened too early, resulting in a large circulation of coolant and a low temperature of coolant;
4. There is air resistance in the engine cooling system, which leads to poor circulation of the cooling system, resulting in high water temperature and warm air.
The water temperature has come up, and the warm wind blows the cool wind.
We need to check whether the vehicle has turned on the cooling button. Generally speaking, the vehicle cooling button will be indicated by the "A/C" key. When the refrigeration button is pressed, the compressor of the air conditioner will be turned on, and the cold and warm air will be blown together at this time, which will lead to the temperature drop of the warm air. If the problem still occurs after shutdown, it is necessary to check the water tank temperature sensor. If the sensor fails and the cooling fan is always on, the warm air will get cold.
When the car is cold, the warm air makes an abnormal noise.
The abnormal sound of warm air is probably due to the insufficient lubrication of the motor rotor, which grinds away the distance between the stators and leads to the gap. Turn on the blower, the speed is very high, and naturally there will be squeaking noise. In this case, we can only replace the worn bearings in the blower. If the blower is seriously damaged, it is recommended to replace it directly. There are few problems in daily use of automobile blowers, and there is generally no problem in inspection during maintenance.
