What is the original reason why the fan is broken while the car is walking?

The car cooling fan does not rotate may be caused by a clogged air conditioner filter, missing refrigerant or a clogged warm air tank, or it may be a faulty relay and a problem with the temperature control switch. If there is no problem, it is the fault of the line, generally speaking, the line from the relay to the temperature control switch.

What are the reasons why car fans don't turn:

1. The air conditioner filter is blocked; The heater is not too hot first check the air conditioning filter to see if it is dirty or blocked, the air conditioning filter is dirty and can indeed affect the heat and cold of the heater, because if it is too dirty, the wind blowing out is very small, and you may not be able to detect it.

2. Lack of refrigerant liquid; If there is a lack of antifreeze, it will also affect whether the warm air is not hot. Because the warm air uses the heat of the antifreeze, the hot antifreeze enters the warm air water tank, heats the warm air water tank, and the wind blows out through the warm air water tank to be hot air. If the antifreeze is not enough, the number of small water tanks that are flushed to the warm air will be reduced, and the filling will not be enough, so the warm air tank will not be so hot, so the wind blowing out will not be so hot.

3. The warm air water tank is blocked; The warm air water tank is blocked, and the antifreeze cannot enter the warm air water tank, or it enters very little, so the warm air water tank will not be hot, and the wind must not be hot after it is blown out.

The easily damaged is the crystal oscillator, which is generally encapsulated in yellow plastic with two legs; This is followed by an infrared emitter, which is at the front end of the remote control.

If the car fan is broken, the car will not be able to drive: 1. Otherwise, the temperature of the cooling water will rise sharply, causing the water tank to boil and the coolant to spray out. If it is serious, it will cause the engine to get stuck and the engine to be scrapped; 2. The cooling fan is an important part of the vehicle cooling system, and the performance of the fan directly affects the heat dissipation efficiency of the engine, which in turn affects the performance of the engine; 3. If the fan is not selected properly, the hall rush will lead to insufficient or excessive cooling of the engine, resulting in the deterioration of the engine working environment, which will affect the performance and service life of the engine.

If the car fan is broken, the car will not be able to drive. Otherwise, the temperature of the cooling water will rise sharply, causing the water tank to open and the coolant to spray out. If it is serious, it will cause the engine to fail and the engine will be scrapped.

The cold osmosis fan is an important part of the vehicle cooling system, and the performance of the fan directly affects the heat dissipation effect of the engine, which in turn affects the performance of the engine. If the fan is not selected properly, it will lead to insufficient or excessive cooling of the engine, resulting in the deterioration of the engine working environment, which in turn will affect the performance and service life of the engine.

The most correct way for the engine cooling fan to break is to stop and wait for rescue or trailer, if it is necessary to drive away under extraordinary circumstances, it is necessary to carry out emergency treatment, specific operation steps:

1. Press the brake pedal to prepare to start the engine.

2. Press the one-button start button.

3. The instrument lights are all lit up, which proves that the engine is started.

4. Turn on the maximum air volume of the vehicle's air conditioning and heating system, and increase the thermal capacity through the small water tank in the car.

5. Open the windows of the car to improve the heat dissipation capacity of the heater.

6. Check the water temperature meter of the vehicle, and turn off the engine and stop to cool down every time the standard water temperature is higher than 90 degrees.

It can be opened, but it can only be used for a short distance, at this time it has nothing to do with whether the fan is good or not, the fan turns again after the temperature is up, and the high temperature is inside the engine. However, it is still recommended to go for repairs.

There is a problem with the water temperature sensor, or it is a thermostat. Caused by high engine temperatures and lack of antifreeze.

Car fans are generally used to dissipate heat from the water tank. By model, the economical one is a big fan. Luxury cars generally have two small fans. Luxury car fan Feed water tank cooling Air conditioning box in front of the water tank.

The air flow driven by the fan work helps the water temperature drop, but the water temperature is not as low as possible, the engine temperature is too low, and of course, the thermostat water pump and so on work together, so it must reach a certain temperature before dissipating heat.

How to solve the car fan does not turn:

Check to see if the water temperature relay is broken, and replace it if it is not in good contact or if it does not respond.

The temperature switch is damaged, so that the fan cannot be powered when the water temperature is high.

If the fan is damaged, it may be that the load of the fan is too large or the short circuit burns out, so it is good to replace it with a new one.

Circuit problems, short circuit and broken circuit will cause the fan not to rotate, carefully check and check, temperature is too important for the engine.

Hello, this situation is most likely that there is a problem with the water temperature sensor, or it is a thermostat. The engine temperature is high and there is a lack of antifreeze, so it is recommended to go to a 4S shop or maintenance point as soon as possible to check it. I hope my answer is helpful to you.

If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

The answer is that the laptop has poor heat dissipation. The CPU needs sufficient heat dissipation when in use, and the fan is for heat dissipation, so the fan keeps rotating. Insufficient fan cooling will cause the CPU temperature to be too high, causing reboot and instability.

If you need to use it for a long time, it is recommended to buy a laptop radiator pad to use underneath, which is not expensive and cheap for dozens of dollars.

At the beginning of the question, the water temperature is normal, and then the fan will not stop after the heat is dissipated, and it will keep turning.

It's still a computer.

Ask about the car.

2010 Buick LaCrosse.

Answer 1: The engine is overheated due to insufficient cooling water; 2. Water tank leakage; 3. The thermostat fails; 4. There is a lot of dust outside the radiator of the water tank. The solution to the car cooling fan keeps rotating is: 1. Add or replace cooling water; 2. Replace the water temperature sensor; 3. Clean up the dust of the radiator.

The replacement method of the car cooling fan is: 1. Open the hood of the car and remove the air intake pipe located on the top of the cooling fan; 2. Unscrew the screws at the four corners; 3. Replace the cooling fan; 4. fixing screws; 5. Install the air intake pipe; 6. Close the hood.

I've read all the questions.

Question: The water tank is new.

Answer: The engine needs to work at a certain temperature to be optimal, and as long as the car starts, it generates heat. Especially when driving at low speeds or in traffic jams, the water temperature rises quickly. However, it should not be raised all the time, and if there is a continuous high temperature, you can check whether the heat dissipation parts are good first.

Is the heat dissipation also normal?

Is the water temperature high? Asking questions is normal at first, but the fan doesn't stop, and then it becomes abnormal.

Answer the fan control unit, the fan control unit includes the control wiring harness, whether it is the control unit or the wiring harness damage can cause the fan to work poorly. First, check the relay of the cooling fan, and then check whether the relevant wiring harness is damaged, aging or short circuit. Problems with any unit will cause the fan to work abnormally.

It's just that the fan feels abnormal.

Hello, it is generally caused by the water temperature sensor [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

The problem of the car has been rotating depends on the situation, the water temperature of the car is normal, and the fan does not stop, most of them are because the thermostat is broken or the function of this sensor is not installed. It is to detect the water temperature of the engine, and when the water temperature becomes high, it will turn the fan. If it fails, the fan will remain in working condition regardless of the water temperature.

The advantage is that the water temperature will not be high in summer, and the disadvantage is that there is no warm wind in the winter acacia shouting sky.

Methods of using maintenance:

1. Under normal circumstances, after the water temperature reaches the established temperature, the thermostat is opened, and the water of the water tank is circulated.

2. In the case of low temperature, the fan is rarely started when the vehicle is driving. If Qiaoqi feels abnormal, you can step on the accelerator on the spot and try it within 2500 rpm, and the fan will rotate in about 10 minutes under normal circumstances. It is basically determined that in the case of the vehicle installing a thermostat, the water temperature is not high or the pot is not boiled, there should be no problem.

It's best to go to the service station and check the temperature of the water.

3. When using antifreeze, in order to avoid the corrosion of the radiator, be sure to use a long-term anti-rust antifreeze produced by a regular manufacturer and in line with national standards.

4. In the process of installing the radiator, please do not damage the heat sink belt (piece) and touch the lead wide field radiator to ensure the heat dissipation capacity and sealing. (Photo by Zhang Fengxue) Xpeng Motors P7 Model Y AION V Ideal One NIO EC6 Model X @2019
