A fan of the GL8 car does not turn on the air conditioner, and the air conditioner is turned off, an

Check if there is a voltage input to this fan, if there is, it proves that the fan is broken, if not, check the circuit, relay, temperature switch!

If a fan does not rotate, it is still possible to maintain idle speed, such as turning on the air conditioner or increasing the load, the engine water temperature will definitely rise quickly, if the set temperature is exceeded, the computer will specify the engine to increase the speed to increase the circulation of the cooling system to try to reduce the water temperature!

If there is an obvious abnormal noise, it can no longer be opened! If you want to solve the fan problem quickly, the rest will be solved!

As for the speed of the belt, it is loud, check if the belt is loose and slippery!

Two fans One is the water temperature fan The other is the air conditioning condenser fan It is recommended to check the water temperature sensor Fan relay After you turn on the air conditioner, the speed is loud, which should mean that the condenser fan is no problem Check the radiator fan If the speed is high, it is necessary to circulate water to dissipate the heat Your fan is broken, it must be higher It's not a big problem If you have a problem, you can send a private message to the station!

You know, you're not just a problem with air conditioning! I have a feeling you're having a problem with the throttle cord too, and it's been a long time since you've changed your oil and antifreeze or something! You'd better go get the car repaired and overhauled! Otherwise, it's over!

Hello, when the engine is running at high speeds, the vibration and noise generated by the vehicle are much louder than usual. If there are foreign objects or modified parts in your engine compartment, there may be resonance and abnormal noise. You can check it yourself to determine the squeaks and squeaks**.

If none of the above situations exist and abnormal noises occur frequently, please go to the 4S shop and have your vehicle inspected by a professional technician. For more information, please contact**: 400-820-2020

Check the electronic fan and engine idle control valve.

Cars: What a profound question!

1. The main control switch has poor contact.

Maintenance method: Use a multimeter to measure the contact resistance of the main control switch, when the resistance is too large or zero, it should be repaired or replaced.

2. The fan motor coil is damaged.

Maintenance method: Use a multimeter to measure the contact resistance of the main control switch, when the resistance is too large or zero, it should be repaired or replaced.

3. The set screw between the motor of the fan and the fan blade is loose.

Maintenance method: Tighten the set screws.

4. The fan capacitor is open or short-circuited.

Repair method: Check the capacitor and replace it with a capacitor of the same specification.

It is said that if the air conditioner wants to use it well, it needs to be paid attention to the installation, and the industry people say that the air conditioner is "three points of quality, seven points of installation", and the air conditioner is regarded as a semi-finished product after leaving the factory, and it can be considered a finished product after the correct installation and debugging. Therefore, if you want the air conditioner to be easy and smooth to use, you must pay attention to it when installing it.

How car air conditioners work.

The automotive air conditioning and refrigeration system is composed of a compressor, a condenser, a liquid storage dryer, an expansion valve, an evaporator and a blower. Copper pipes and high-pressure rubber pipes are used to connect them into a closed system. The refrigeration system works, and the refrigerant circulates in a closed system in different states.

Each cycle has four basic processes:

1. Compression process: inhale the low-temperature and low-pressure refrigerant gas at the outlet of the evaporator, compress it into high-temperature and high-pressure gas and discharge it out of the compressor.

2. Heat dissipation process: The superheated refrigerant gas at high temperature and high pressure enters the condenser, and is condensed into liquid to dissipate heat by the reduction of pressure and temperature.

3. Throttling process: the volume of the refrigerant liquid with higher temperature and pressure becomes larger after passing through the expansion device, and the pressure and temperature drop sharply, and the expansion device is discharged with fine droplets.

4. Endothermic process: the mist refrigerant liquid enters the evaporator, and the boiling point of the refrigerant is much lower than the temperature in the evaporator, so the refrigerant liquid evaporates into gas.

Summary. The probable cause is the phenomenon of the compressor protection device tripping.

Compressor overload protection will trip, indicating that the system is too high-pressure, the pressure is too high, or the overheating current is too high.

Causes and elimination of high pressure and overheating:

1. Too much refrigerant. Reduce the refrigeration dose appropriately. (most likely scenario).

2. Poor heat dissipation. Check the condenser pipe for dirt and dirt and clean the condenser.

3. The pipeline system is blocked. Refer to the pressure gauge to judge, eliminate, and re-process systematically.

4. Dust and fouling of the evaporator or filter screen. The airflow becomes smaller, the system pressure and temperature are unstable, and the evaporator or filter is cleaned.

5. Fluoride deficiency is also possible. When there is a lack of fluorine, the compressor discharge temperature will overheat, causing the overheating load protection switch to trip.

Buick GL8 turns on the air conditioning fan, only low speed, not high speed.

Hello, I am the answerer Mr. Xiaobu, your question is from me, it takes a little time to type, please be patient.

Okay, please wait.

The probable cause is the phenomenon of the compressor protection device tripping. Compressor overload protection will trip, indicating that the high pressure of the system is too high or the rock is overheated, and the electricity is quietly diverted too much. Causes and elimination of high pressure and overheating:

1. Too much refrigerant. Reduce the refrigeration dose appropriately. (most likely scenario) 2, poor heat dissipation.

Check the cold coarse condenser tube for dirt and dirt, and clean the condenser. 3. The pipeline system is blocked. Refer to the pressure gauge to judge, eliminate, and re-process systematically.

4. Dust and fouling of the evaporator or filter screen. The airflow becomes smaller, the system pressure and temperature are unstable, and the evaporator or filter is cleaned. 5. Fluoride deficiency is also possible.

When there is a lack of fluorine, the compressor discharge temperature will overheat, causing the overheating load protection switch to trip.

It is recommended that you go to the 4S shop for comprehensive maintenance and overhaul.

Ok thanks.

You're welcome, dear.

Summary. Hello dear, your question gives you the following answers: 1. The relay is faulty:

If the water temperature meets the requirements and the car radiator fan still does not work, then there may be a problem with the relay of the fan, if the relay fails, the car radiator fan will not work. 2. Whether the water temperature meets the requirements: Most of today's car radiator fans use electronic temperature control to work, so generally only when the water temperature in your car reaches the required temperature, the fan will start to rotate normally.

3. Problems with the temperature control switch: If there is no problem in the above two aspects, then it is necessary to check the temperature control switch, this place sometimes has some faults, which will also have a certain impact on the operation of the car radiator fan, so you should also pay attention to the inspection.

Why does the car not turn on the high-speed fan as soon as it is turned on, and it turns without turning on the air conditioner.

Dear, hello, your question will give you the following answers: 1. Relay failure: If the water temperature meets the requirements, the car radiator fan still can't work, then there may be a problem with the relay of the fan, if the relay fails, the car's radiator fan can't work.

2. Whether the water temperature meets the requirements: Most of today's car radiator fans use electronic temperature control to work, so generally only when the water temperature in your car reaches the required temperature, the fan will start to rotate normally. 3. There is a problem with the temperature control switch

If there is no problem in the above two aspects, then you have to go to the wheel to check the temperature control switch, this place sometimes has some faults, and it will also have a certain impact on the operation of the car radiator fan, so you should also pay attention to check.

There are also high-speed fans that are not powered when they turn.

Is the car unpowered?

The high-speed fan is powerless as soon as it turns.

This is not the case with the air conditioner turned on.

The head gasket is flushed! It is advisable to check if the cylinder pressure and water are sufficient! Is there a high temperature alarm for the engine temperature?

The water is sufficient, and then the temperature does not alarm.

Then the air conditioner will not run out of power when it is turned on?

The air conditioner will have enough power when it is turned on, and it will not keep the high-speed fan running.

Then you probably have a broken fan controller.

It is recommended that you take a look at the fan controller.

If the fan controller is bad, does it have anything to do with the power?

Yes. It will cause insufficient power and high fuel consumption.

You can see if the fuel consumption has become higher.

Summary. Hello, master, in this case, you first need to check whether the compressor can run when you turn on the air conditioner? If the compressor is operational, check whether the control module of the fan or the fan itself is damaged.

If the compressor is not running, you need to check whether the pressure switch of the air conditioner and the air conditioner data are normal. Hello, master, please provide an accurate and clear vehicle factory license plate and 17-digit frame number**. Describe the cause of the failure of the vehicle and the fault phenomenon, so that I can provide you with maintenance ideas and treatment solutions.

First, give me a clear factory sign. I'll send you a data map here for your reference.

The car air conditioning compressor can't add a bottle of freon after the second bottle is finished. In the end, three bottles of Kongshi seepage were added, and the high-speed fan did not rotate, only the low-speed fan rotated, the low-pressure gauge had high air pressure, the high-pressure gauge remained unchanged and judged, and the compressor temperature was high.

In this case, you first need to determine if the compressor is working properly. And diagnose whether the pressure of the air conditioner displayed on the computer is normal?

The compressor is working fine.

Then you use the diagnostic computer action to test whether the fan has a high-speed fan, if the heat dissipation is not good here, it will affect the effect of the air conditioner, why does the air conditioning pipe not leak Why do you add three bottles of freon after the low pressure gauge is high, I thought it was too much to add the inch freon that I emitted out.

Then check this situation first. Is there a problem with the expansion valve of the air conditioner?

1. If the air conditioner is a fixed-speed air conditioner, the fan of the air conditioner does not rotate, which is a very normal phenomenon, the air conditioner is working, when the indoor temperature reaches the standard temperature you set, it will automatically stop working, and the outdoor fan of the air conditioner will continue to operate normally after the indoor temperature rises.

2. The fan of the outdoor unit of the air conditioner does not rotate may also be due to the following fault causes.

1. The fan motor of the air conditioner is damaged, the solution: determine that the fan of the air conditioner is not rotating caused by the damage of the motor, and only need to replace the fan motor.

2. The capacitor of the starting fan is damaged, the solution: replace the capacitor.

3. The bearing of the fan is damaged by the foreign body card or the bearing, solution: if it is caused by foreign matter, only clean the bearing, and replace the bearing with a new one.

4. The compressor is damaged, Solution: The fan of the air conditioner caused by the compressor does not rotate, and the compressor can only be replaced.

Answer: If the air conditioning switch is not in good contact, it cannot control the normal start of the car air conditioner, and the two cannot be connected, so the fan of the car air conditioner does not rotate. In this case, replace the air conditioner control switch, and pay attention to whether there is a short circuit in the connecting wire of the switch.

2. The fan motor coil is damaged: If the fan motor coil is damaged, the fan cannot supply energy normally, so it does not rotate. In this case, the coil of the fan motor should be inspected and repaired, and it can be replaced directly if necessary.

3. Fan bearing falling off: When the fan bearing falls off, when the air conditioner is turned on, only the bearing idles and the fan cannot rotate normally, in this case, the fan bearing should be reinstalled and fixed.

4. The water temperature does not meet the requirements: As of July 2019, most of the car fans on the market use electronic temperature control technology to work, and the air conditioning system can only work normally if the water temperature reaches the standard. If it is normal for the air conditioner fan not to rotate because the water temperature does not meet the standard, you only need to warm the car to make the water temperature reach the normal standard.

The air conditioner turned on the first, second, third, and first gears and did not respond, and the 4th gear was OK, for what reason.

Hello Now in this weather, turning on the air conditioning fan will definitely have to turn.

If the air conditioner does not turn, first check whether the air conditioning system is normal:1Whether the refrigerant is sufficient. If there is a lack of refrigerant, first find the leak point, and after dealing with it, then observe it.

2.Whether the compressor and its wiring are normal.

3.Whether the pressure switch of the air conditioner and its wiring are normal.

If there is no problem with the air conditioning system, observe whether there will be high temperatures when the vehicle is running normally without turning on the air conditioner.

If there is a high temperature, then it is necessary to check:1Whether the fan is mechanically faulty. 2.Whether the fan wiring, including the wiring of the fan control part, is normal.

In short, if you can't solve it, ask for help from a professional repair shop or 4S shop.
