How to Solve a Clogged Car Air Conditioner?

When a car's air conditioner is clogged, it is necessary to replace it with a new air filter. The reason for a clogged car air conditioner is the icing of the evaporator, which blocks the air duct and reduces the airflow. The control valve of the variable displacement compressor should be checked for normal operation, or the control valve should be replaced directly. If the airflow is relatively small when using the external circulation mode but normal when using the internal circulation mode, it indicates that the air filter is clogged. A new air filter needs to be replaced to solve the problem. When the filter is excessively dirty, the circulating airflow of the air conditioner will decrease. Additionally, severe dust and dirt accumulation in the air conditioner's supply and return air ducts can also lead to a reduction in circulating airflow. When the refrigeration system is operating, the refrigerant circulates in different states within this closed system, with each cycle consisting of four basic processes: Compression process: The compressor inhales low-temperature, low-pressure refrigerant gas from the evaporator outlet and compresses it into high-temperature, high-pressure gas, which is then discharged from the compressor. Heat dissipation process: The high-temperature, high-pressure superheated refrigerant gas enters the condenser. Due to the decrease in pressure and temperature, the refrigerant gas condenses into a liquid, releasing a significant amount of heat. Throttling process: The high-temperature, high-pressure refrigerant liquid passes through the expansion device, causing its volume to increase and its pressure and temperature to drop sharply. It is then discharged from the expansion device in the form of mist (small droplets). Heat absorption process: The vaporized liquid enters the evaporator, where the boiling point of the refrigerant is much lower than the internal temperature of the evaporator, causing the refrigerant liquid to evaporate into a gas. During the evaporation process, it absorbs a large amount of heat from the surroundings, and then the low-temperature, low-pressure refrigerant vapor enters the compressor. This process is repeated to lower the temperature of the air around the evaporator.

How to Use Lights for Temporary Parking at Night in Subject 3?

Turn on the parking lights and hazard warning lights. Rotate the headlight switch to the parking light position and press the hazard warning light button. Below is an introduction to the use of lights at night in Subject 3: 1. Poor night lighting: Turn on the parking lights and headlights, and use high beams for illumination. Rotate the headlight button on the light combination switch all the way, then observe the dashboard to check if the low beam indicator lights up. If it lights up, it indicates that the low beams are on. Push the entire light combination switch outward; if the high beam indicator lights up, it indicates that the high beams are on. 2. Following a vehicle closely at night: Switch from high beams to low beams. When in high beam mode, pull the light control lever inward once. If the high beam indicator turns off and the low beam indicator lights up, the lights are in low beam mode. 3. Meeting another vehicle at night: When the oncoming vehicle is about 150 meters away, switch from high beams to low beams. Pull the light control lever inward once; the high beam indicator turns off, and the low beam indicator lights up, indicating low beam mode. 4. Passing through special intersections: Alternate between high and low beams to signal. Repeatedly push and pull the light control lever to alternate between high and low beams. 5. Driving in fog: Turn on the parking lights, fog lights, and hazard warning lights. Rotate the headlight control button to the parking light position, then rotate the fog light switch to the front and rear fog light positions to turn on the fog lights. As for the hazard warning lights, simply press the warning light button. 6. Traffic breakdown: Turn on the parking lights and hazard warning lights. Rotate the headlight switch to the parking light position to turn on the parking lights. Then press the hazard warning light button to activate the warning lights.

What are the differences between Subject 1 and Subject 4?

The main differences between Subject 1 and Subject 4 include: different number of questions, different question types, different proportions of exam content, different exam focuses, and varying levels of difficulty and pressure. The information is based on the "Regulations on the Application and Use of Motor Vehicle Driving Licenses." Number of Questions: The most obvious difference between Subject 1 and Subject 4 is the number of questions. Subject 1 has 100 questions, while Subject 4 only has 50. In Subject 1, the exam automatically submits if you answer more than 10 questions incorrectly, whereas in Subject 4, the exam submits after 6 incorrect answers. Question Types: Subject 1 consists of 100 questions, each worth 1 point, with a total exam time of 45 minutes. The question types are true/false and single-choice questions, with a full score of 100. Subject 4 has 50 questions, each worth 2 points, and also lasts 45 minutes. The questions are primarily in the form of case studies, images, and animations, with question types including true/false, single-choice, and multiple-choice, also totaling 100 points. Exam Focus: Subject 1 mainly tests basic road driving knowledge, while Subject 4 focuses on safe and civilized driving practices. In simple terms, Subject 1 is about how to drive, and Subject 4 is about how to drive safely. Though the difference is just the word "safe," the focus is entirely different. Exam Content Breakdown: Subject 1 Content: Driving license and motor vehicle regulations (20%); road conditions and traffic rules (25%); traffic violations and penalties (25%); accident handling regulations (10%); basic vehicle knowledge (10%); local regulations (10%). Subject 4 Content: Safe driving practices (20%); civilized driving practices (18%); application of traffic signals in scenarios (8%); driving in adverse weather and complex road conditions (16%); emergency avoidance (12%); case studies of accidents (6%); accident rescue and hazardous material handling (10%); local test questions (10%). Difficulty and Pressure: Subject 4 includes multiple-choice questions and is the final test in the driving exam, making it more stressful and slightly more difficult than Subject 1. There are no limits on the number of attempts for Subject 1 and Subject 4. If you fail, you can reschedule. Each scheduled exam allows two attempts. If both attempts are unsuccessful, you must retake the exam until you pass. Both Subject 1 and Subject 4 are theoretical exams and are part of the motor vehicle driving license assessment. The driving exam consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the traffic laws and regulations knowledge test. Subject 2 is the field driving skills test. Subject 3 is divided into two parts: road driving skills and the safe and civilized driving knowledge test. The safe and civilized driving test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, the official term (as per the Ministry of Public Security Order No. 123) does not include "Subject 4."

How to Reset the Tire Warning on a Changan Vehicle?

Slow down and brake gently to stop safely, avoid sharp turns, correct the tire pressure when the tires are cold, and replace the tire if necessary. If the Tire Pressure Monitoring System detects low pressure in one or more tires, a warning message will appear on the display, and the tire pressure warning light will illuminate. In case of a puncture causing air leakage, check which tire is leaking and inflate it accordingly. Sudden drops in temperature can also cause abnormal tire pressure. Wait until the temperature stabilizes, and it will return to normal.

How to Restore Car Navigation to Factory Settings?

Method to restore car navigation to factory settings: There is a REST reset button on the navigation system. Use a sharp object to press it, and the system will restart. Note that the REST reset button is hidden and requires pressing and holding for a few seconds. Car navigation works by using an onboard global positioning system combined with an electronic map. It provides drivers with the shortest or fastest route to their destination. The navigation system includes features such as a DVD player, radio reception, Bluetooth hands-free, touchscreen, optional functions, intelligent reverse trajectory, tire pressure monitoring, and background control.
