Why is the car air conditioning cooling down very slowly?

Here are the reasons why the car air conditioning cools down very slowly: 1. Excessive refrigerant causing insufficient cooling. This usually occurs due to overcharging of refrigerant during maintenance, as there is a specific proportion requirement for refrigerant volume in the air conditioning system. 2. Insufficient refrigerant causing a lack of cooling. The main cause of insufficient refrigerant is usually leakage in the system. 3. Excessive impurities in the refrigerant and lubricating oil, causing minor blockages and insufficient cooling. If there are too many contaminants in the refrigerant and lubricating oil throughout the air conditioning system, the filter screen will inevitably become clogged, reducing the flow capacity of the refrigerant, increasing resistance, and decreasing the amount of refrigerant flowing to the expansion valve, leading to insufficient cooling. 4. Moisture infiltration in the air conditioning refrigeration system causing insufficient cooling. There is a component in the refrigeration system called the dryer (or receiver), whose main task is to absorb moisture from the refrigerant to prevent excessive moisture from reducing cooling capacity. 5. Air in the system is another cause of insufficient cooling. Once air enters the air conditioning system, it will increase the pressure in the refrigeration lines, and poor refrigerant circulation will also lead to insufficient cooling. 6. Reduced heat dissipation capacity of the condenser will also lead to decreased cooling performance of the air conditioning system. 7. Other reasons, such as low power supply voltage causing reduced electromagnetic clutch engagement or oil contamination between the clutch pressure plate and the pulley, can result in "slipping" phenomena similar to a loose drive belt.

What to Do If Your Driver's License Has Been Deducted More Than 12 Points?

If the points deducted reach 12, after the driver's license is confiscated, you must go to the relevant authority within 15 days to study road traffic safety laws, regulations, and related knowledge, usually for 7 days. After that, the vehicle management office will conduct a test within 20 days. If you fail, you must continue studying and taking the test. If you pass, the points will be cleared, and your driver's license will be returned. The handling method for deducting 12 points in one scoring cycle is as follows: 1. Within 15 days, go to the traffic management department of the public security authority to participate in a 7-day study of road traffic safety laws, regulations, and related knowledge (Subject One), then take the test. If you pass, the points will be cleared; 2. If a motor vehicle driver accumulates 12 points in one scoring cycle, the traffic management department of the public security authority shall confiscate their motor vehicle driver's license; 3. The motor vehicle driver shall, within 15 days, go to the traffic management department of the public security authority at the place where the driver's license was issued or where the violation occurred to participate in a 7-day study of road traffic safety laws, regulations, and related knowledge. After the motor vehicle driver completes the study, the vehicle management office shall conduct a test on road traffic safety laws, regulations, and related knowledge within 20 days; 4. If the test is passed, the points will be cleared, and the motor vehicle driver's license will be returned. If the test is failed, the driver must continue studying and taking the test. If the driver refuses to participate in the study or take the test, the traffic management department of the public security authority will announce the suspension of their motor vehicle driver's license.

Can You Turn Right When There's a Red Light Without a Right-Turn Arrow?

There are three scenarios where vehicles can turn right at a red light, as detailed below: Circular Traffic Light: If the circular traffic light at an intersection turns red, vehicles in the right-turn lane can proceed to turn right. However, you must ensure not to interfere with other vehicles, pedestrians, and vehicles on the right side of the road. Arrow-shaped Right-Turn Signal: If you encounter an arrow-shaped right-turn signal at an intersection, you must not turn right when the red arrow is lit. Turning right under these conditions will be considered running a red light. Circular Red Light with Additional Signage: At some complex intersections, you may find additional signage above the traffic light indicating whether right turns are permitted during a red light. If the sign says "Right Turn on Red," then it is allowed. If it says "No Right Turn on Red," you must wait for the green light before turning. Legal Regulations: According to the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," motor vehicle and non-motor vehicle traffic signals are defined as follows: When the green light is on, vehicles are permitted to proceed, but turning vehicles must not obstruct the passage of straight-moving vehicles or pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue to proceed. When the red light is on, vehicles are prohibited from proceeding. At intersections without non-motor vehicle or pedestrian crossing signals, non-motor vehicles and pedestrians should follow the motor vehicle traffic signals. When the red light is on, right-turning vehicles may proceed if they do not obstruct the passage of other vehicles or pedestrians. The "Road Traffic Safety Law" stipulates the following regarding traffic signals: Article 25, Paragraph 2: Traffic signals include traffic lights, traffic signs, road markings, and the directions of traffic police. Article 26: Traffic lights consist of red, green, and yellow lights. Red indicates prohibition, green indicates permission, and yellow serves as a warning. Article 38: Vehicles and pedestrians must follow traffic signals. In the presence of traffic police directing traffic, follow their directions. On roads without traffic signals, proceed under the principles of safety and smooth traffic flow. Article 62: Pedestrians crossing intersections or roads should use crosswalks or pedestrian facilities. At signalized crosswalks, follow the traffic signals. At unsignalized intersections or road sections without pedestrian facilities, cross only after ensuring safety. Article 89: Pedestrians, passengers, and non-motor vehicle drivers violating road traffic laws and regulations may receive a warning or a fine ranging from 5 to 50 yuan. Non-motor vehicle drivers refusing to pay fines may have their vehicles impounded. Driving a motor vehicle in violation of traffic signals results in a 6-point penalty. Right-Turn Precautions: Observe Oncoming Straight Traffic: When turning right, check both the right and left sides for oncoming vehicles. Watch for Opposite Left-Turning Vehicles: Besides straight-moving vehicles, be aware of any left-turning vehicles from the opposite direction. Yield to them before proceeding. Be Mindful of Pedestrians: Right turns often involve crosswalks at both the approach and the corner. Always check for pedestrians before turning.

Does Tire Cleaner Damage Tires?

Tire cleaner can damage tires. Here are the detailed explanations: 1. Aging and cracking: Car tires are typically made of vulcanized rubber. As one of the most harshly working components on a vehicle, tires constantly endure impacts and temperature changes, which over time leads to aging and cracking, rendering them unusable. 2. Forming a protective layer: High-quality tire shine can form a protective film on the tire surface. Although this film doesn't last long, it generally helps protect the tire, thereby extending its service life.

What Are the Causes of Cracks in Car Tires?

Car tires may develop cracks due to poor tire maintenance, and damaged tires should be replaced promptly. Here is a detailed introduction to car tires: 1. Overview: Car tires are one of the essential components of a vehicle, directly in contact with the road surface. Together with the car suspension, they help absorb shocks during driving, ensuring a comfortable ride and smooth operation. 2. Function: They ensure good adhesion between the wheels and the road surface, enhance the vehicle's traction, braking, and off-road capabilities, and bear the weight of the car. The critical role tires play in vehicle performance is increasingly being recognized.
