Buick Hideo gt air conditioner can't blow hot air.

1, the cooling system is short of coolant, which is also commonly known as antifreeze, and the warm air of the automobile air conditioner comes from this. The principle is different from that of household air conditioning heating. Automobile warm air circulation is to connect a pipeline in parallel in the small circulation pipeline of engine coolant, which is connected with a warm air tank, and the blower blows the warm air tank to generate warm air.

That's how air conditioning and warm air come about. The lack of coolant in the cooling system is the most common and easily solved fault phenomenon that causes the warm air not to be hot.

Solution: Add coolant in time.

2. The heater water tank is blocked. The structure of the warm air water tank is actually a miniature version of the radiator of the engine water tank, and there are many small cooling pipes in it, which are as easy to block as the radiator of the water tank. After the inside of the warm air water tank is blocked, the coolant flows slowly, the flow rate becomes smaller, and the heat is insufficient, so the air conditioner warm air is naturally not hot.

Solution: dredge the warm air tank in time.

3, warm water valve failure

Warm water valves are common in luxury brands, and are actually electrically controlled valves. The warm water valve is installed between the water inlet pipe of the warm water tank and the small circulating pipeline of the engine, and the opening of the valve is controlled by the air-conditioning computer, so as to control the flow rate of coolant entering the warm water tank and achieve the purpose of controlling the warm air temperature of the air conditioner more accurately.

Solution: Repair and replace the warm water valve.

Judging whether the air conditioning system is running well is actually very simple. If it is found that the air conditioning system is not well cooled, the air volume is small, or there is no cooling at all, it is necessary to check whether the components are operating normally and whether there is a lack of condensing agent. The condenser must be added according to the model in the vehicle manual. All these can be done in specialty store.

In summer, the temperature difference between inside and outside the car is large. When entering the car, it is not advisable to adjust the air conditioning temperature too low immediately. You can use a lot of natural wind to blow away the hot air in the car first, then don't close all the windows, turn on the air conditioner, and wait until your body gets used to it, then adjust the air conditioner to the required temperature and close the windows. In this way, our bodies will not be uncomfortable because of the sudden drop in external temperature.

The temperature of the air conditioner is not as low as possible. The most comfortable temperature for human body is about 23 degrees Celsius. In the sunny afternoon in summer, the air conditioner should not be turned on too low, which can not only resist the scorching sun in summer, but also ensure that the ambient temperature of the human body is not too low, which leads to "air conditioning disease" and also responds to the call of the state for energy conservation, emission reduction, low carbon and environmental protection.

Passengers had better not smoke in the car when the air conditioner is turned on. Because the air in the car circulates in a relatively closed environment when the air conditioner is turned on, first, the smoke is not easy to escape, and second, the tiny particles in the smoke will attach to the air inlet filter screen of the air conditioner, resulting in long-term odor in the car.

Regular professional air conditioning system cleaning, sterilization and deodorization maintenance.
