What to Do When the Car Air Conditioning Compressor Fails to Start?

Use a multimeter to conduct sectional testing of the circuit, identify the fault point, and repair it. If the Freon refrigerant is depleted, it will affect the insufficient return of the refrigeration oil. Replenish the refrigerant. Prolonged operation under high-speed load conditions may cause premature mechanical wear of compressor components. Replace the worn parts. An overly tight drive belt can directly cause the compressor to jam and stop operating. Therefore, regularly check the tension of the drive belt.

How to Take the Subject 1 Test with a Temporary ID Card Without a Magnetic Strip?

For the Subject 1 test, as long as the ID card has a photo and relevant identity information, a temporary ID card can be used after obtaining a certificate from the local police station when replacing it. Electronic IDs are not accepted for the test. If you don't have an ID card, you can apply for a temporary one, which holds the same validity as a formal ID card. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," the Subject 1 test can be taken twice on the same day. If you fail the first attempt, you can retake it for free. If you fail the second attempt, the test is terminated, and you can only reschedule after ten days. The Subject 1 test consists of 100 questions, including single-choice and true/false questions, each worth 1 point, totaling 100 points. If you answer 11 questions incorrectly, the system will automatically submit the test and end it. The Subject 1 test is computer-based and lasts 45 minutes. Subject 1 Test Content: Regulations on driving licenses and motor vehicle management; Road traffic conditions and regulations; 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 passenger and freight vehicles; Specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject 1 Test Notes: During the test, candidates should dress appropriately—no slippers are allowed. Electronic devices and bags are prohibited in the test 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 lockers before entering the test room. At the test room, the identity verification desk will assign a seat. Once seated, begin the test. Ensure the camera is aligned with you and follow test discipline. If you fail the first attempt, you can retake it the same day. If you fail again, you must pay to reschedule. After the test, queue to collect your score sheet and sign it. Without a signature, the result is invalid. There is no limit to the number of times you can reschedule the Subject 1 test. Each subject can be taken once, with one retake if you fail. If you do not take the retake or fail it, the test is terminated, and you must reschedule. For Subject 2 and Subject 3, there are only five attempts. Subject 2 and Subject 3 tests can be rescheduled after ten days. If you fail the Subject 3 safe driving knowledge test, the previously passed road driving skills test results remain valid. There are three subjects in the driving test: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the test on road traffic safety laws, regulations, and related knowledge. Subject 2 refers to the field driving skills test. Subject 3 is divided into two parts: road driving skills and safe driving knowledge. The safe driving knowledge 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 Solve the Abnormal Noise from Car Air Conditioning Compressor?

Years of driving can inevitably cause the electromagnetic clutch to be contaminated with dirty water, leading to abnormal noise. Replacing the compressor bearing can solve the issue. The car air conditioning compressor has relatively high requirements for the electromagnetic clutch during operation. You can replace the internally damaged parts or the entire assembly. Repeated engagement of the electromagnetic clutch can lead to insufficient power generation from the alternator, causing the compressor to operate with insufficient voltage and resulting in abnormal noise.

What Causes a Car to Stall While Driving?

Here are the specific reasons why a car may stall while driving: 1. Poor clutch control. Proper clutch control is key to avoiding stalling when starting. Manual transmission cars are prone to stalling if the clutch is released too slowly, so when starting, press the clutch pedal with your left foot and slowly release it as the car begins to move. 2. Throttle not synchronized. While controlling the clutch, it's important to also apply the throttle; failing to do so can cause stalling. Therefore, lightly press the throttle while releasing the clutch for a smoother start. 3. Handbrake not engaged. Before shifting into gear to start, make sure to engage the handbrake. 4. Driving at high gear with low speed. During normal driving, if the car is in a high gear but moving at a low speed, the engine may shake, lose power, and stall. It's important to shift gears at the right time—generally, shift to 3rd gear at 40 km/h, 4th gear at 50 km/h, and 5th gear at 60 km/h, and so on.

What to Do When the Tire Pressure Monitoring Sensor is Broken?

Tire pressure monitoring sensors cannot be repaired by oneself and require replacement at a professional auto repair shop. Below is an introduction to tire pressure monitoring sensors: 1. The tire pressure monitoring system, abbreviated as "TPMS", stands for "tire-pressure-monitoring-system". This technology can automatically monitor various conditions of the tires in real-time by recording the rotation speed of the tires or through electronic sensors installed in the tires, providing effective safety assurance for driving. 2. The tire pressure monitoring system can be divided into two types: one is the indirect tire pressure monitoring system, which determines whether the tire is abnormal by detecting differences in tire rotation speed; the other is the direct tire pressure monitoring system, which involves installing four tire pressure monitoring sensors inside the tires to automatically monitor tire pressure and temperature in real-time, whether the vehicle is stationary or in motion, and promptly alerts for high pressure, low pressure, or high temperature in the tires to prevent traffic accidents caused by tire failures, ensuring driving safety.

Do You Need to Press the Accelerator When Reversing a Manual Transmission Car?

Manual transmission vehicles generally require pressing the accelerator when reversing. Below are the specific details about reversing a manual transmission car: 1. Manual transmission vehicles require pressing the accelerator when reversing; otherwise, the engine may stall during the process. While reversing, the clutch is used to adjust the power output and control the speed. 2. If the road conditions are good and the driver is skilled, the accelerator can be pressed when reversing. Otherwise, idling speed can be used to achieve reversing. 3. During poor weather conditions or when visibility is low at night, avoid pressing the accelerator when reversing. Instead, use the engine's idling speed to drive the vehicle to ensure safety.
