It is likely that the compressor has malfunctioned and needs to be repaired promptly. Introduction: Automotive air conditioning refers to the air conditioning device installed in a car, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers. It significantly reduces driver fatigue and improves driving safety. Structure: Generally, it includes refrigeration devices, heating devices, and ventilation devices. This combined system makes full use of the limited space inside the car, featuring a simple structure and easy operation, making it a popular modern automotive air conditioning system internationally.

Last time after my car went through water, the air conditioning wasn't cooling either. The mechanic later said it might be due to water entering the electrical system. The air conditioning control module is located near the chassis and is prone to short circuits after being submerged, causing signal disruptions that prevent the compressor from working. There was also the issue of blown fuses—my own fuse box was full of moisture at the time, with several fuses blackened. Additionally, it's a common problem for sensors to be corroded by accumulated water, preventing them from sending cooling commands. Actually, if you notice the AC isn't cooling, you should stop and check immediately—don't keep driving and risk burning out the computer board. If necessary, disconnect the battery to cut power and have the car towed to a repair shop for circuit inspection. After all, modern cars have many electronic components, and malfunctions after water exposure are quite common.

What are the precautions and detailed procedures for buying and selling used cars?

Vehicle inspection, engine number tracing, license plate removal, photography → Traffic violation inquiry and handling → Payment of transfer fee → Transfer registration → Receipt of receipt form → Collection of vehicle license and registration certificate. Ensure the legal compliance of the vehicle's documents, check the vehicle's documents, registration certificate, vehicle license, and then compare the chassis number and engine number. Start the engine to listen for any abnormal sounds, fully depress the accelerator pedal and then suddenly release it to observe if there is any shaking. Inspect the most hidden parts of the vehicle. If inconsistencies are found, it may indicate that the vehicle has undergone major repairs or significant accident repairs or replacements.

Is the Volkswagen Magotan a Four-Wheel Drive Car?

Only the imported models of the Magotan are equipped with a four-wheel drive system. It is worth mentioning that the price of the imported models is relatively higher than that of the domestically produced models. Below is an introduction to the imported models of the Magotan: In terms of power, the imported Magotan models are equipped with a 2.0T turbocharged engine and a four-wheel drive system. This engine has a maximum power of 155 kW and a maximum torque of 280 Nm. In terms of transmission, the engine is paired with a 6-speed dual-clutch transmission, which is not the classic 7-speed dual-clutch transmission commonly used by Volkswagen. The basic structure of the four-wheel drive system uses an electronically controlled multi-plate clutch as the central differential. During normal driving, most of the power is distributed to the front axle of the car. When the front wheels slip, the four-wheel drive system will distribute 50% of the power to the rear axle.

How Far Can a Rearview Camera See?

Rearview cameras can typically see distances of over 3 meters, but there is no universal answer to this question as the visible range varies depending on the brand and model of the vehicle. When the rearview camera is activated, the central display usually shows three colored lines: red, yellow, and blue. The red line indicates the closest distance, typically around 30 centimeters, allowing the driver to turn or continue reversing. The yellow line represents a distance of about 1 meter, requiring heightened attention to avoid collisions. The blue line indicates the farthest distance, usually around 3 meters. Rearview cameras serve only as an auxiliary tool and should not be relied upon entirely. This is because the images displayed by rearview cameras often exhibit significant distortion, differing from the actual distance proportions in reality. Some high-end vehicle models now feature 360-degree panoramic rearview cameras. A 360-degree panoramic rearview camera provides real-time, stitched images of the vehicle's surroundings on the display screen, offering an ultra-wide, seamless view. It helps drivers understand blind spots around the vehicle, enabling more intuitive and safer parking.
