Inspect and repair the clutch electromagnetic coil, and readjust the clutch clearance according to specifications. Replace the compressor bearing. If internal parts or the assembly of the compressor are damaged, replace the damaged parts or the entire assembly. When refrigerant is insufficient, identify the cause of the leak, repair it, and then add refrigerant. If the compressor's refrigeration oil level is too low, add compressor refrigeration oil.

Once when I turned on the air conditioning in my Wuling Hongguang, I also heard an abnormal noise—a buzzing sound that was quite annoying. Later, I found out it was a leaf stuck in the fan blades. After cleaning it, the noise disappeared. I recommend turning off the engine and waiting for it to cool down after parking, then carefully opening the hood to inspect the fan or compressor area for any blockages. Use tweezers to gently remove any debris. It could also be due to loose or worn belts causing friction noise. A simple test of belt tension can determine if it's too loose or tight. Alternatively, internal components of the compressor might be loose, resulting in a clicking sound. Avoid setting the air conditioning to the highest setting immediately—try lowering the fan speed to see if the situation improves. If the noise persists, visit a repair shop promptly to check the compressor, refrigerant, and other components to prevent a minor issue from escalating into a major fault that could affect driving. Regularly cleaning the air conditioning filter and engine compartment dust can also help prevent abnormal noises and prolong the lifespan of your air conditioning system.

Can laundry detergent be used to wash cars?

It is not recommended to use laundry detergent for car washing because laundry detergent is not specifically designed for cleaning car bodies. Some laundry detergents are alkaline cleaners, and prolonged use can damage the car body, causing the paint to become dull and lose its shine over time. It is advisable to use dedicated car wash soap, which is specially formulated to provide better cleaning and stain removal for the car body without irritating the skin. The correct car wash solution should be a dedicated car wash soap, preferably one that contains wax. During the car washing process, computer car washes use professional car wash soap with a neutral pH, which does not erode the car's surface and contains water wax components. This not only cleans the car but also provides a moisturizing and protective effect, enhancing the paint's shine without causing damage. It is best to go to a professional car wash shop that offers fully automated high-pressure washing, foam spraying, gentle scrubbing without damaging the paint, full chassis cleaning and maintenance, as well as wax spraying, drying, and polishing. After the car comes out of the car wash machine, only a chamois cloth is needed to wipe the mirrors, ensuring excellent cleaning results, saving time, and protecting the car.

Are Brake Caliper Covers Illegal?

Installing brake caliper covers will result in failing the annual vehicle inspection. Introduction to Automotive Brake Caliper Covers: Automotive brake caliper covers mainly use high-temperature resistant adhesive, but they tend to fade over time, resulting in a very unattractive appearance. If low-quality caliper covers are used, they may fall off and get stuck in the tire's mechanical parts, or the metal rods on the covers could puncture the tire, causing a blowout. This is extremely dangerous during high-speed driving, so for the sake of driving safety, it is advisable not to install them. Braking System: Brake calipers are clamping devices designed to slow down, stop, or maintain the stopped state of a moving wheel, typically used only in disc brake systems. The working principle of disc brakes can be described using the analogy of a rotating disc: if you pinch the disc with your thumb and index finger, the disc will stop rotating. In this analogy, the thumb and index finger represent the function of the brake caliper.

Do traffic cameras capture the front or rear of motorcycles for violations?

Generally, the rear is captured because underground induction loops are typically installed, with digital cameras mounted on crossbars for snapshots. This requires two pulse signals to be generated simultaneously within the same time interval (during the red light cycle) to be considered "valid." For example, if the red light is on and the front wheel of the vehicle crosses the line while the rear wheel has not yet crossed, only one pulse is generated. Without two consecutive pulses, no photo is taken. Methods for capturing red-light violations: At traffic intersections, there are generally two methods for capturing red-light violations. One involves underground induction loops with digital cameras mounted on crossbars to snap photos of red-light runners. The other uses mounted cameras to record real-time footage of speeding, red-light running, and illegal parking. At least three images are captured: Regardless of the method, at least three images are taken of the violating vehicle: one showing the moment of the violation, one for license plate recognition, and one providing a full-view image. Both methods operate 24/7, and the images are typically retained for one week.

Is the annual inspection for small cars every six years or every two years?

After the implementation of the new vehicle inspection regulations, small cars between 6 and 10 years old require an inspection every 2 years. At the 6th and 8th year, the vehicle must undergo an on-site inspection. For private cars over 10 years old, the original inspection cycle still applies: vehicles between 10 and 15 years old require an annual inspection, while those over 15 years old require an inspection every 6 months. Operational passenger vehicles: Operational passenger vehicles must be inspected annually within the first 5 years; after 5 years, they require an inspection every 6 months. Freight vehicles: Freight vehicles and large or medium-sized non-operational passenger vehicles must be inspected annually within the first 10 years; after 10 years, they require an inspection every 6 months. Small and mini non-operational passenger vehicles: Small and mini non-operational passenger vehicles must be inspected every 2 years within the first 6 years; after 6 years, they require an annual inspection; after 15 years, they require an inspection every 6 months.

How Many Traffic Violations Will Lead to Vehicle Towing by Traffic Police?

What to Do If the Vehicle Transfer Is Not Accepted?

If the vehicle has not been transferred, it means the vehicle registration remains local, and the update indicator generally cannot be obtained. The vehicle management office usually provides a receipt when processing the transfer procedures, requiring the transfer to be completed within 30 days at the designated vehicle management office. The transfer requires the vehicle owner or a designated agent to handle the process. If the transfer-out procedures were initially designated to be handled by the buyer's representative, even the vehicle owner cannot proceed with the transfer now. The update indicator certificate can only be issued approximately one week after the vehicle transfer is completed. According to Article 19 of China's Motor Vehicle Registration Regulations, when applying for transfer registration, the current motor vehicle owner must fill out an application form, inspect the motor vehicle, and submit the following documents: the current motor vehicle owner's identity proof; proof of motor vehicle ownership transfer; the motor vehicle registration certificate; the motor vehicle driving license; for motor vehicles under customs supervision, the Customs Supervision Vehicle Release Certificate of the People's Republic of China must also be submitted.
