What is the cause of FAW Besturn X80 air conditioner failure?

Without refrigeration, use the double-head pressure gauge to check whether the operating pressure is normal? See if there are any leaks? If no leak is found, check if the refrigerant is insufficient.

Check whether the condenser is normal, the expansion valve is normal, and the compressor is normal. If all of the above checks are normal, the air conditioner should cool down normally.

Common faults of automotive air conditioning compressors.

1. Leakage Refrigerant leakage is the most common problem in air conditioning systems. The leakage of the compressor is usually at the junction of the compressor and the high and low pressure pipes, which is usually troublesome to inspect due to the installation location. The internal pressure of the air conditioning system is very high, and when the refrigerant leaks, the compressor lubricating oil is lost with it, which leads to the air conditioning system not working or the lubrication of the compressor is poor.

There are pressure relief protection valves on the air conditioning compressors, and the pressure relief protection valves are usually used once, and the pressure relief protection valves should be replaced in time after the system pressure is too high for pressure relief.

2. Not working There are many reasons why the air conditioner compressor does not work, usually because of problems with related circuits. The compressor can be preliminarily checked for damage by supplying direct power to the compressor's electromagnetic clutch.

3. Abnormal noise There are many reasons for abnormal noise of compressors. For example, the compressor electromagnetic clutch is damaged, or the internal wear of the compressor is serious, etc., can produce abnormal noise.

1) The repeated engagement of the electromagnetic clutch will also cause abnormal noise in the compressor. For example, insufficient power generation from the generator, high pressure in the air conditioning system, or excessive engine load can cause the electromagnetic clutch to engage repeatedly.

2) Reliable lubrication is required when the compressor is working. When the compressor lacks lubricating oil, or the lubricating oil is not used properly, there will be serious abnormal noise inside the compressor, and even cause the compressor to wear and tear and scrap.

3) There should be a certain gap between the electromagnetic clutch and the compressor installation surface, if the gap is too large, then the impact will also increase, if the gap is too small, the electromagnetic clutch will work with the compressor installation surface between the motion interference, which is also a common cause of abnormal noise.

4) The compressor electromagnetic clutch is a common part of abnormal noise. The compressor often runs from low speed to high speed under high load, so the requirements for the electromagnetic clutch are very high, and the installation position of the electromagnetic clutch is generally close to the ground, and it will often come into contact with rain and soil, and when the bearing in the electromagnetic clutch is damaged, it will produce abnormal noise.

5. Press the air conditioning button in the lower left corner of the FAW Besturn X80 center console to turn off the air conditioning button, as shown in the mark below, so that the air conditioning device of the Besturn X80 will be turned off.

FAW Besturn X80 turns off the air conditioning device, opens the door of the driver of FAW Besturn X80, and presses the brake pedal of FAW Besturn X80 to prepare to start the engine; The specific steps are as follows:

1. Open the door of the FAW Besturn X80 driver.

2. Press the brake pedal of the FAW Besturn X80 to prepare to start the engine.

3. Press the one-button start button of FAW Besturn X80.

Fourth, the instrument lights of FAW Besturn X80 are all lit up, which proves that the engine is started.

5. Press the A C button of FAW Besturn X80 located in the lower left corner of the center console to turn off the air conditioning device.

Press the AC air conditioner switch of the center console.

How to use: It is the air conditioner switch, max is the biggest meaning, and the internal circulation can be manually switched on.

2.When the default air conditioner is turned on to the maximum state (or when the temperature difference between the inside and outside of the car is relatively large), the internal circulation will be automatically started; In other cases, the internal loop is generally not automatically opened.

Fault phenomenon: The buttons on the control panel are out of order, and the remote control can be operated.

Reason analysis: because the remote control operation can be received, so it can be ruled out that it is the main computer board problem, after checking the display board on the key scanning with the D1 D12 two electrode front diode uses a low-frequency diode to read Jianqing in4007, and the main program for the processing of the key is high-frequency; The individual control panel is incompatible with its own motherboard, and the main program cannot respond correctly to the signal sent by the key during key operation, resulting in the failure of key operation.

Solution: When such faults are found, the D1 D12 diode on the control panel can also be replaced with an IN4148 high-frequency tube.

Experience summary: in addition to the DS key failure, FS (Y) temperature adjustment button failure may also fail, the display panel design considers that the gap left by the button feel is small, the plastic panel button deformation of the plastic branch, and the gap between the panel is too small to cause operation failure, and the fault only needs to replace the same type of control panel.

In this case, first confirm whether it is a panel problem or a line problem, it is better to confirm it than the panel line, first check the fuse, whether the panel power supply iron signal line is normal, if it is normal, it is the panel inside the question to guess the Sun virtual chain problem needs to repair the panel, I hope mine can help you.

In general, the failure of the car remote control lock may be caused by the car body or the remote control key itself. The failure of the time control module in the remote control key, the aging of the antenna of the remote control transmitter in the car, etc., may cause the remote control key to not work. Due to the cold weather, some of the remote control is greasy and sticky, resulting in poor contact, resulting in the failure of the car remote control lock.

The Besturn X80 is based on the M1 platform, and in terms of power, the old Besturn X80 will be equipped with or engines, with a maximum power of 146 horsepower and 154 horsepower respectively, and a peak torque of 183Nm and 205Nm respectively. State empty.

The 2015 Besturn X80 inherits the advantages of Besturn X80 configuration and excellent quality, and the biggest change is the new model plus power model, equipped with 4GC series high-performance supercharged engine, and adds sports models on the basis of the original model. The 2015 Besturn X80 has a T power that combines high dynamics and economy, and meets the China V emission standard.

250,000 kilometers of low failure, stable performance, and comprehensively improve the driving experience. The 2015 Besturn chassis features a front-to-rear independent suspension that is the first in its class. Through the use of higher strength body and more advanced safety devices, it has achieved the C-NCAPX80 crash 5-star level.

Teng X80 sales were not high before, although it is not like Haval H6, Baojun 510 sales champions, but it can still support a large share of FAW Besturn. After entering 2016, the Besturn X80 seems to have changed, and sales are bleak. In fact, this is the biggest problem with the Pentium X80:

1. In terms of product quality, Besturn X80 was originally favored by people. Because the chassis of the Besturn X80 is independently developed on the basis of the chassis of the Mazda 6; The gearbox adopts Aisin's; The engine is an upgraded version of the Mazda6. It can be said that the Besturn X80 uses Mazda's technology, and everyone hopes to develop a product that satisfies everyone;

2. However, the Besturn X80 still disappointed everyone, and there were many failures in the engine, gearbox and chassis, which showed that FAW Besturn made a big mistake in the adjustment and assembly of the crude products. In the later versions, the Pentium X80 should have been improved to a certain extent, but the previous word-of-mouth and negative impact have affected the later facelifted X80, which is why the sales of the Pentium X80 are not high;

3. The product quality is not enough, and the after-sales service will make up. Compared with the product quality of the Besturn X80, what makes car owners intolerable is its after-sales service level. After the problem with the vehicle, the 4S shop not only did not solve it or even did not answer the owner's inquiry**; Reflected in the 400 customer service, the manufacturer's attitude is still the same and does not reply.

The imperfect after-sales service level has undoubtedly further intensified the contradiction between Muyun consumers and car companies. It can be seen from the data of the car quality network that there are nearly 100 service complaints about the Besturn X80.

Millions of car purchase subsidies.

There are 3 situations that need to be paid attention to when the Besturn X80 air conditioner is not refrigerated:

1.Too much refrigerant causes insufficient refrigeration and too much refrigerant to the day.

2.Too little refrigerant leads to a shortage of refrigerant.

3.Refrigerants and refrigerator hand oils contain too many impurities and micro-blockage, resulting in insufficient refrigeration capacity and energy efficiency. The energy efficiency of air conditioning is an important factor to consider when buying an air conditioner, how to use the minimum energy consumption to achieve the maximum efficiency, some air conditioners may consume thousands of electricity in a year, and some even exceed the price of air conditioners, so how do we identify the energy efficiency of air conditioners when buying?

In fact, when we buy, we only need to look at the energy efficiency label on the air conditioner, energy efficiency represents the energy saving degree of the air conditioner, and the energy efficiency level is mainly divided into five levels, compared with the first level of energy efficiency is the best, so when we buy air conditioners, we can try to buy air conditioners with energy efficiency.

Function. The function of air conditioning is also very important, the refrigeration and heating of air conditioning generally belongs to the basic skills of the silver to cultivate energy, now many manufacturers have begun to develop to health, comfort, silence, automatic cleaning, etc., many functions have also been initially realized, so we can also choose the functions we need when purchasing air conditioners.

Serve. The purchase of air conditioning is one thing, and the installation and after-sales service is particularly important, after the purchase of air conditioning is just a product, we need to install it reasonably, in order to play its due role. Therefore, we also have to compare the installation and service of air conditioning manufacturers and brands, and it is particularly important to choose an air conditioning manufacturer and brand with service specifications, complete after-sales, and punctual and efficient installation.
