What Causes Abnormal Noise from the Air Conditioner?

Here are the reasons for abnormal noise from the air conditioner: 1. Excessive pressure in the high-pressure pipe of the air conditioning system. 2. Dirty condenser leading to poor heat dissipation. 3. Blocked expansion valve causing high pressure in the pipeline. Here are the key points for troubleshooting air conditioner faults: 1. Observe the working conditions of the indoor and outdoor units: such as the display on the indicator panel, whether the indoor unit is working, whether the fan speed output is normal, and whether the outdoor unit fan and compressor are running, to determine whether the issue is electrical or system-related causing the lack of cooling. 2. Check various data of the air conditioner: water leakage from the air conditioner, continuous dripping from the indoor unit indicates normal operation, but this can only be used as a reference value as it is influenced by environmental humidity and temperature. The temperature difference between the air inlet and outlet should normally be 12-14 degrees, but this can also be affected by ambient temperature and fan speed.

What are the differences between the Haval H9 and the Maxus D90-Pro?

The differences between the Haval H9 and the Maxus D90-Pro are as follows: Power: The Haval H9 is equipped with the 4C20B-2.0T engine, a direct-injection turbocharged engine independently developed by Great Wall Motors, with a power reserve of 165kW/385Nm (1800~3600rpm). The actual driving experience is commendable, with a 0-100km/h acceleration time of around 10 seconds, which is quite impressive for a body-on-frame hardcore SUV. The D90 diesel version has a clear advantage in power, achieving good acceleration with the same maximum power, reaching 0-100km/h in 11 seconds—a benchmark among diesel vehicles in its class. The maximum torque of 500Nm provides stronger low-speed burst power, along with the advantage of low fuel consumption. Four-wheel drive: The Haval H9 uses BorgWarner's TOD on-demand four-wheel-drive system, with a transfer case integrating a multi-plate clutch limited-slip differential. The D90 Pro supports an optional part-time four-wheel-drive system, whose transfer case does not have a limited-slip differential.

Why is the left side of the Audi A6 blowing cold air while the right side blows hot air?

Audi A6's left side blowing cold air while the right side blows hot air is caused by a malfunction in the car's heating valve. The reasons for heating system failure in cars include: 1. Premature opening of the thermostat: Outdoor cold air rapidly cools the antifreeze, preventing the engine water temperature from rising, which inevitably results in no hot air from the heater. 2. Air lock in the engine cooling system: Air lock causes poor circulation in the cooling system, leading to high water temperature and no hot air from the heater. Relevant information about the Audi A6 is as follows: 1. Vehicle dimensions: Length, width, and height are 5012 mm, 1855 mm, and 1485 mm respectively, with a wheelbase of 2945 mm. 2. Engine type: 3.2L/V-type 6-cylinder/4-valve/fuel direct injection. 3. Fuel consumption: 7.4 liters per 100 kilometers.

How to deal with minor plastic scratches on the rearview mirror?

Here are specific methods for dealing with minor plastic scratches on the rearview mirror: 1. Fine wax and coarse wax: Apply wax to the scratched area of the vehicle. 2. Use a touch-up pen: This method is suitable when the vehicle's primer has not been damaged. 3. Rust-proof paint and spray paint: First use a rust remover, then apply spray paint, and finally repair with fine wax and coarse wax. Here are additional details: Types: Vehicle scratches are categorized as minor, moderate, and deep. Minor scratches are shallow and mainly affect the paint surface. Moderate scratches refer to damage to the surface paint layer but not the vehicle's original paint. Deep scratches generally refer to those that have damaged the primer. For such damage, the owner needs to use rust-proof paint and spray paint for repair. Once the vehicle's primer is damaged, it can easily cause rust in the scratched area, so it is necessary to repair it promptly with rust-proof paint and spray paint. For shallower scratches, simply applying wax is sufficient.
