Volkswagen Bora 2003 does not have a warm air

1. The heating valve is faulty.

The heating valve is actually an electronically controlled valve, which is installed between the inlet pipe of the heating water tank and the small circulation pipeline of the engine, and the opening of the valve is controlled by the air conditioning computer, so as to control the flow of coolant into the heating water tank, so as to achieve the purpose of more accurate control of the temperature of the heating air conditioner.

After the failure of the heating water valve, the opening of the electric control valve is no longer controlled by the computer, and is in a state of normally open, normally closed or a certain position is not moving, at this time, there is no coolant flow or flow is not controlled in the warm air tank, and the temperature of the air conditioner is naturally uncontrolled.

2. The cooling system lacks coolant, and the heating air of the automobile air conditioner comes from this. Automobile warm air circulation is a parallel pipeline in the small circulation pipeline of engine coolant, which is connected to the warm air water tank, and the blower blows the warm air water tank to produce warm air, which is how the air conditioning warm air comes. The lack of coolant in the cooling system is the most common and easiest fault phenomenon that causes the warm air to not heat up.

Hello friend winter is coming, usually this situation will occur, generally that, the thermostat on the engine, there is a failure, and the warm air tank is blocked, this phenomenon will occur, it is recommended that you check the thermostat first, if there is no problem with the thermostat, then you need to blow the warm air tank with high-pressure air, blow it several times, if it still doesn't work, then you need to replace the water supply tank, this warm air tank is the easiest to block. I hope I can help you, if you have any questions, please feel free to contact me. BBA Mercedes-Benz BMW Audi Maintenance wishes you a happy life, all the best, and a lot of money!

If the water temperature is normal, don't consider the thermostat and check the heater control switch.

Hello, is it not the small water tank of the heater is broken.

The engine is not hot enough, and the warm air is naturally not hot.

Generally, the reason why the heater of the car is not hot enough after turning on may be two main reasons, the cooling system of the engine or the control mechanism of the heater is caused by problems and not working properly. The owner can check the temperature of the two inlet pipes of the small water tank of the heater, if the temperature is hot enough, it means that there is no problem with the heating control mechanism, if it is cold or one hot and one cold, it means that there is a problem with the cooling system.

And the cause of the problem with the engine cooling system could be:

1. The cooling system of the engine is affected by air resistance, which causes the cooling circulation system of the car to not operate normally, which leads to the problem that the warm air is not hot.

2. The water pump impeller of the vehicle is damaged or lost, resulting in a decrease in the amount of water flowing through the water tank, resulting in the warm air not being hot, and a new water pump impeller needs to be replaced.

3. It is also possible that the thermostat is always turned on or turned on too early, causing the cooling system to circulate in advance, and the temperature outside the vehicle is low, and the external cold air will cool the antifreeze quickly, resulting in the temperature of the water tank not rising enough and the warm air not hot enough. The thermostat needs to be adjusted or repaired.

The things you need to pay attention to when buying a car are as follows:

1. Confirm the purchasing ability

Determine the purchasing power, after buying a car does not affect the overall quality of life of the family, generally according to the average income of the family in the past three years, generally take out 20% of the family for three years, but not more than 10% of the value of the family's fixed assets.

2. Concerns:

The most important thing for a family car is safety, followed by affordability, because the safety of the car carries the life of a family, so safety is the top priority.

3. On-site confirmation:

According to the above two steps, basically determine the several models to buy, and go to the 4S store to confirm on the spot, including test drive, inquiry, loan, repair and maintenance, and other related information.

The heating of the air conditioner in the car should first talk about the position of the heating and heating switch to the heating (red), because the heating of the vehicle is mostly the heat of the water tank, and there will be no warm air when the vehicle is just started, and the temperature of the water tank can only be adjusted after the temperature of the water tank rises. If the temperature of the water tank does not come out after the temperature rises, it is necessary to check whether the pipes and fans are normal.

The heating of the car is obtained by the increase in the water temperature of the engine, and the water temperature does not reach the optimal working temperature when the engine is just started, so the heating does not feel hot, and the heating will become hotter and hotter as the water temperature gradually increases.

Hello. The temperature of the vehicle's heater is the temperature of the vehicle's engine coolant. You need to wait until the engine is hot before the heater will come out normally.

In addition, check the switch of the air conditioner knob to check whether it is in the wrong position. If the temperature rises, there is still no warm air later. It is advisable to check if the amount of coolant is missing?

Hope it helps, hope, thank you.

The heater is not hot when it is first started, and it is recommended that the water temperature is 60 degrees before turning on the heater.

In 17 years, the Bora heater is not hot, and the pump assembly is still not hot.

Summary. Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions!

Volkswagen Bora warm air is not hot, first of all, you need to check whether the antifreeze is lacking. In the case that there is no shortage of antifreeze, try the two pipes connected to the heater water tank on the engine, and the temperature is not the same. If a tube is hot.

There is a tube that is not hot. This lighting heater tank is blocked. You can first use a simple method to remove this pipe with a water gun for car washing.

Rinse. If there is no effect after rinsing. This one heater tank needs to be replaced.

There is another situation that you need to check whether the motor that regulates the heating and cooling air is stuck. The heating of the air conditioner in the car must first adjust the heating switch to the heating position, because the heating of the vehicle is mostly the heat of the water tank. When the vehicle is just started, there will be no warm air.

Wait for the temperature of the tank to rise.

Volkswagen Bora heater is not hot What's going on 12 models.

Volkswagen Bora 16 automatic transmission left side of the warm air does not dissipate the disadvantages of the heat what is the reason for the pro, hello! The reasons are as follows: First, the heater tank is clogged.

The structure of the warm water tank is actually a smaller version of the radiator of the tank of a simple engine engine. There are a lot of small heat pipes in there, which are just as easy to clog as the tank radiator. When the inside of the heater box is clogged, the coolant will slow down, the flow will be reduced, and the heat will be insufficient.

The air-conditioned heater naturally does not heat up. Secondly, the cooling system lacks coolant. Coolant, commonly known as antifreeze, is the first air heating for cars, and its principle is different from that for home air heating.

Automobile warm air circulation is to connect the pipeline in parallel with the small circulation pipeline of engine coolant, which is connected with a warm air box, and the blower blows the warm air box to produce warm air. This is how the air is conditioned. Insufficient coolant in the cooling system is the most common fault phenomenon that causes the warm air to not heat up, and it is also the easiest to solve.

In the end, the thermostat failed. The common fault of the thermostat is that it cannot be opened, but the reason why the heater is not hot due to the failure of the thermostat is that the thermostat cannot be opened, commonly known as the thermostat is always on. When the thermostat is turned on normally, the coolant will start circulating from engine idle.

If the water temperature in the north is low for a long time in winter, the air heating air will naturally not be hot, and it can be clearly seen from the water temperature gauge that the hand is significantly lower than the normal scale. In addition, if the engine water temperature is too low for a long time, it will lead to excessive oil consumption and increased wear, so if the engine water temperature is too low for a long time, it needs to be repaired and checked immediately.

1. The automatic constant temperature function of the air conditioner is working, and the car constant temperature air conditioner automatically adjusts the air intake and cooling capacity according to the temperature in the car; 2. Caused by the failure of the air-conditioning and refrigeration system, such as: adding too much refrigerant, the air-conditioning filter is dirty, the refrigerant is insufficient, and the expansion valve is broken.

The possible reasons for the air conditioner of the car to cool down for a while and not for a while are:

1. The automatic constant temperature function of the air conditioner is working, and the car constant temperature air conditioner automatically adjusts the air intake and cooling capacity according to the temperature in the car;

2. Caused by the failure of the air-conditioning and refrigeration system, such as: adding too much refrigerant, the air-conditioning filter is dirty, the refrigerant is insufficient, and the expansion valve is broken.

Car Air Conditioning Maintenance:

1. Comprehensively inspect the air conditionerWhen using the air conditioner for the first time in summer, the air conditioning system should be checked first, such as checking whether the refrigerant and air conditioning filter are too dirty and whether the radiator has foreign objects through the liquid storage tank.

2. Regularly open the large air volumeSome car owners rarely or never turn the air conditioner to a large air volume because they don't like the noise made when the air conditioner is turned on to a high gear. However, the air conditioner will suck in a lot of dust when it is used, and it is a simple way to keep the air conditioner clean by turning on the wind energy regularly to blow out the floating dust on the inner surface of the air conditioner.

3. After parking, do not turn off the air conditioner, and after the owner arrives at the destination, he generally closes the air conditioner door and leaves directly. Unlike autumn and winter, the huge temperature difference between the inside and outside of the car during the hot summer months can cause mold to grow in the air conditioning system, which in turn can breed mold. Therefore, the owner should turn off the air conditioner and turn on the natural air a few minutes before arriving at the destination, so that the temperature in the air conditioning duct rises and eliminate the temperature difference with the outside world, so as to keep the air conditioning system relatively dry and avoid the reproduction of mold bends.
