Is 'OFF' in a car on or off?

What is the reason why the air conditioning of the Baojun 730 is sometimes cold and sometimes not?

The reasons why the air conditioning of the Baojun 730 is sometimes cold and sometimes not: 1. Lack of refrigerant: This is the main reason why most vehicles encounter air conditioning failures in summer. When the refrigerant in the car's air conditioning pipes is insufficient, the pressure in the air conditioning pipes decreases, and the amount of heat removed also decreases. This can give the impression that the air conditioning is not blowing cold air. Therefore, it is essential to regularly check the refrigerant pressure during routine maintenance to avoid leaks or insufficient pressure. 2. Dirty condenser: The purpose of cleaning the radiator and condenser is mainly for heat dissipation. If the condenser is clogged with poplar catkins in spring or dust from smog, it can lead to phenomena such as excessive engine temperature or poor air conditioning. Therefore, it is necessary to check whether the radiator is clogged with many fibers after spring. When cleaning, be sure to first use an air gun to blow it clean, and then use a water gun to wash it, otherwise it will have the opposite effect, not only resulting in poor air conditioning but also increased fuel consumption. 3. Loose air conditioning compressor belt: This situation is caused by the aging of the compressor belt, which causes the compressor to slip during operation, reducing work efficiency, lowering rotational speed, and impairing the effective delivery of refrigerant. At this time, the compressor belt should be tightened. If the aging is too severe, it is recommended to go directly to a professional repair shop to replace the belt. 4. Air in the air conditioning pipes: If air is mixed into the car's air conditioning system during operation, it will affect the refrigerant's circulation, significantly reducing the cooling effect. The main cause of such problems is mostly the incomplete evacuation of air during the maintenance process.

How Long Is the Validity Period of Subject 1?

According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," the validity period of the study driving certificate after passing Subject 1 is three years, but the expiration date must not exceed the upper age limit for application. If Subject 1 is not passed, there is no validity period. Applicants must complete Subject 2 and Subject 3 within the validity period. If the exams are not completed within the validity period, the passing scores of the already completed subjects will be invalidated. Subject 1, also known as the theoretical driving test or driver theory test, is part of the motor vehicle driving license examination. The test content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The test format is computer-based, with a time limit of 45 minutes. Subject 1 consists of 100 questions, including single-choice and true/false questions, each worth 1 point. If 11 questions are answered incorrectly during the test, the system will automatically submit the test and end the exam. Subject 1 Test Content: Driving license and motor vehicle management regulations; road traffic conditions and rules; road traffic safety violations and penalties; road traffic accident handling regulations; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized buses and trucks; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject 1 Exam Notes: During the exam, candidates must pay attention to their attire—no slippers are allowed, and electronic devices and bags are prohibited in the examination room. Bring your ID card and queue to enter the waiting hall. Observe the instructions and procedures on the large screen, and store personal belongings in the lockers before entering the examination room. Upon entering, verify your identity at the assigned seat and begin the test. Ensure the camera is focused on you and follow exam discipline. If you fail the first attempt, there is a same-day retake. If you fail again, you must pay to reschedule. After completion, queue to collect your score sheet and sign it—unsigned sheets are considered invalid. There is no limit to the number of times you can schedule the Subject 1 exam. Each subject can be taken once, and if you fail, you can retake it once. If you do not take the retake or fail the retake, the exam ends, and you must reschedule. Subjects 2 and 3, however, allow only five exam attempts. If you fail the Subject 3 safe and civilized driving knowledge test, the passing scores for the road driving skills test remain valid. There are three subjects in the driving test: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the road traffic safety laws, regulations, and related knowledge test; Subject 2 refers to the field driving skills test; Subject 3 is divided into two parts: road driving skills and safe and civilized driving knowledge. The safe and civilized driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, the official terminology (i.e., the Ministry of Public Security's Order No. 123) does not include the term "Subject 4."
