What is the problem that the Nissan Qashqai does not have cold air

Hello! Generally, it is caused by insufficient refrigerant, system leakage, and failure of the air conditioning electronic control system. You need to have a specific inspection, if you don't understand, you can ask, I wish you a happy life!

Dongfeng Nissan Qashqai has the following ten disadvantages:

1. There is nothing new in appearance.

The Qashqai is the main family model, but it is not difficult to find that even the latest facelifted Nissan Qashqai is not much different from the Qashqai from 5 years ago in terms of appearance. The Qashqai itself is already very mediocre in appearance, and it will not be a facelift for many years, consumers have long been aesthetically tired of the Qashqai, and Nissan needs a facelift as soon as possible to keep up with the trend of the market.

2. The power output of the engine is too weak.

The engine equipped with the Qashqai has the ultimate fuel economy, and the fuel consumption can be less than 8 liters in the city, but the problem of insufficient power of the Qashqai is very obvious when it is on the highway, especially when overtaking with full load. There is no comparison with engines of the same class.

3. The CVT gearbox is "greasy", and I am afraid that the steel belt will be disconnected.

In recent years, it is not uncommon for Sylphy's CVT gearbox to have steel belt fractures, and Nissan officials have also made it clear that this problem cannot be solved, and it can only be repaired by replacing the steel belt. The Qashqai is also equipped with this CVT gearbox, so it is necessary to pay more attention to the wear and tear of the steel belt during maintenance.

4. The panoramic sunroof cannot be opened.

Skylights were originally used for daylight and ventilation. Now that it can't be opened, it means that the skylight can't be ventilated, so this configuration is a bit of a chicken rib.

5. The trunk volume is small.

In the same class of models, the trunk volume can basically be more than 500L. But the trunk of the Qashqai is only 486L, which makes the trunk of the Qashqai can only fit two large suitcases. So, if a family needs to dust up a long journey, trunk storage space can be a little tight.

6. The interior design is relatively old.

Now both domestic cars and joint ventures are leaning towards younger design, and the interior of the Qashqai still maintains the design of 10 years ago. Although the large central control screen can keep up with the trend, there is really no bright spot in the interior layout, and the design is too old and uninspired.

7. Sound insulation and noise reduction are relatively average.

Don't say that Qashqai, even the more advanced Loulan doesn't do a good job in sound insulation and noise reduction. The main noises** of the Qashqai are tyre noise and wind noise, especially when the vehicle is traveling at speeds above 100 km/h, and the front row wind noise is noticeable.

8. The rear space is not sufficient.

After all, it is limited by the size of the body, and Nissan is far less experienced than Honda in terms of space design. Therefore, compared to the Honda XRV, the rear space of the Qashqai will be slightly cramped. If your family is taller, the rear longitudinal space of the Qashqai may not be enough.

9. The paint is thin and the texture is average.

The real car of the Qashqai looks like the paint texture is relatively average, and as long as you touch it, you will find that the paint of the Qashqai is relatively thin, and there is a gap compared with German cars of the same level.

10. The roll is large.

The Qashqai is still a comfort-oriented model after all, so it will be softer in suspension tuning. As a result, the Qashqai rolls a lot when cornering in a parallel lane, which doesn't give you confidence in handling when driving on winding roads.

1. The noise caused by the engine is large, and sound insulation materials can be installed in the engine. In this way, it can avoid the noise generated by vibration when the engine is running, and the sound material around the engine can be installed to isolate the noise generated by the engine, which can reduce the transmission of noise. When using this method, it is best to go to a professional place to do it, and do not affect the heat dissipation of the engine because of the installation of Zhaoliang sound insulation materials.

2. If the car is used for a long time, the sealing strip will also lose its original effect, if you want to reduce the engine noise, you can change the door sealing strip by changing the way, it is recommended to choose the flexibility and elasticity when choosing the sealing strip, so that the sound insulation effect will be better.

3. If there is still a lot of noise after replacing the sealing strip, you can also block the noise by installing soundproof cotton for the car.

Almost all Japanese cars such as the Japanese product slow in the brand cold start engine speed is relatively high, the movement is relatively large, this is the design of the factory Min rotten, soon after the heating up, the axle which leakage engine idle speed will drop to the standard value, the engine noise will come down.

If you start cold, the engine sound is loud, and after a minute, it tends to be quiet, and the sound is very small when you start hot, which is a normal phenomenon. This is because the mill oil in the engine automatically flows back into the oil pan when it is stopped.

Why the cold start noise of the Nissan Qashqai engine is so loud must be caused by the roughness of the mechanical production process.

Summary. Hello, happy to answer your <>

The reason why the Nissan Qashqai air conditioner is not refrigerant leaking: the refrigerant in the air conditioning system leaks, causing the system to not work properly. This is due to a broken seal and a loose joint.

Compressor failure: The compressor of the air conditioning system is responsible for circulating the compressed refrigerant, and if the compressor fails, it will not produce sufficient refrigeration. Condenser Issues:

The condenser in the air conditioning system is used to dissipate the refrigerant, and the condenser is blocked and damaged, which will affect the refrigeration effect.

The Nissan Qashqai air conditioner does not refrigerate.

Expansion: Cold slag coagulant is a working fluid used in refrigeration and air conditioning systems, which changes from gaseous to liquid in the cycle, thereby absorbing heat to reduce temperature. The condensate accomplishes this process by changing its physical state, dexterity, and pressure.

In the refrigeration cycle, the condensate is first compressed into a high-pressure, high-temperature gas by a compressor, and then dissipated by a condenser to cool it and condense into a liquid state. At this time, the condensate contains more heat. After that, the condensate enters the evaporator through the expansion valve throttling.

There is no leakage. It's just that the fan and compressor don't work.

The simulated pressure switch turns on the air conditioner and works normally.

Check if the fuse of the air conditioning system is burned out and disconnected. If a blown fuse is found, replace it with a new one of the same type and rating. The pressure sensor in the air-conditioning system detects abnormal pressure and prohibits the operation of the air-conditioner.

The air-conditioning compressor is one of the core components of the air-conditioning system, and the whole system cannot work normally due to faults and cracks.

The fuse does not burn.

How to measure the three-wire pressure switch of the air conditioner.

Locate the pressure switch: In a car air conditioning system, the pressure switch is located near the compressor and there are three wires connected to the switch. You can check the vehicle's Sensitive Burial Manual and consult a professional axle repair technician to determine its exact location.

Detach the pressure switch: Using the appropriate tool, gently remove the pressure switch from its position. You will need to use the corresponding wrench slot to unlock and remove the pressure switch.

Connect the voltmeter: According to the voltmeter's instructions, connect its probe or lead wire with the three wires on the pressure drain switch. Make sure each wire is connected correctly to avoid measurement errors.

Measure Voltage: Turn on the voltmeter and set it to DC voltage DCV mode. Then, restart the vehicle in a safe way and start the air conditioning system.

Observe and record the values displayed on the voltmeter.

Summary. This common is that the motor outside the flap is broken, and this one is still more troublesome to replace, and the instrument panel needs to be disassembled.

Hello, happy to answer your questions.

This still depends on whether you have warmed up the engine in advance, if the engine temperature has risen, but there is no heater, it is very likely that your air conditioning heating and cooling conversion system has failed, this can check whether the balance infiltration conversion flip Xiang rental board is moving, if there is no problem with the conversion flap, then it may be the heating water tank is blocked.

Both the inlet and outlet water are hot.

Then it is possible that there is a problem with the heating and cooling conversion flap.

Is it that the heater water tank can't be opened?

This one has a flap that is used to control the cold and warm air, and you should have this flap not working.

It's easy not to change a flap for this.

This common is that the motor outside the flap is broken, and this one is still more troublesome to replace, and the instrument panel needs to be disassembled.

It's okay to turn on the air conditioner, but it's useless to turn on the heating.

Yes, this should be stuck in the cold air.

Then you have to change the flap.

Check it out first.
