What Causes a Car Air Conditioner to Stop Cooling but Work Again After Restarting?

There is an issue with the air conditioner's receiver-drier. The car air conditioning system includes a receiver-drier, whose main function is to absorb moisture from the refrigerant and prevent excessive moisture in the refrigerant from reducing cooling capacity. When the desiccant inside the receiver-drier becomes saturated, it can no longer filter out moisture. Methods for maintaining a car air conditioner: 1. Comprehensive inspection of the air conditioner: When using the air conditioner for the first time in summer, inspect the air conditioning system, such as checking the refrigerant and whether the air filter is too dirty through the receiver-drier, and whether there are foreign objects in the radiator. 2. Pay attention to cleaning the air conditioner: Some beginners only think about cleaning the air conditioner when its performance deteriorates, which is incorrect. The air filter should be replaced regularly because Beijing's spring has a lot of sand and flying willow catkins, which can stick to the filter and breed bacteria, causing a musty smell in the air conditioner. Additionally, the condenser should be cleaned periodically, and the radiator should be removed for thorough cleaning. 3. Do not turn off the air conditioner immediately after parking: After reaching their destination, car owners usually turn off the air conditioner and leave immediately. Unlike in autumn and winter, the significant temperature difference between the inside and outside of the car in hot summer can cause the air conditioning system to become moldy and breed mold.

Is It Normal for the BMW 3 Series Air Conditioning Compressor Not to Shut Off?

Air conditioning compressor not shutting off could be due to setting issues or air conditioning damage. Reasons for the air conditioning compressor not shutting off: The car's air conditioning temperature is set too low, causing the compressor not to shut off. A faulty temperature sensor leads to the compressor not shutting off. The internal computer board thermostat of the air conditioning unit is broken, causing the compressor not to shut off. A refrigerant leak in the air conditioning refrigeration system results in insufficient cooling, causing the compressor not to shut off. Solutions: If the refrigeration system works normally after turning on the air conditioning, then the fault is likely a thermostat malfunction, and the thermostat system should be checked. First, check if the temperature sensing tube connected to the thermostat has fallen off; if so, it should be fixed back to its original position. Secondly, after prolonged use, the internal contacts of the thermostat may become sintered, the control fluid inside the thermostat may leak, or the thermistor of the electronic thermostat may change value. If the cooling effect is poor, it might be due to refrigerant leakage in the air conditioning system, causing the residual refrigerant to fall below the standard cooling capacity. As a result, the resistance value of the thermistor does not meet the required value, so the air conditioning will not shut off.

What Are the Contents of Car Maintenance?

Car maintenance includes: replacement of engine oil and oil filter, air filter, gasoline filter, and pollen filter; maintenance and replacement of spark plugs; inspection and maintenance of systems such as transmission oil. Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. It should be noted that the air filter and cabin air filter should be inspected first to determine if replacement is necessary. If they are not severely dirty, they can be cleaned and reused; if they are very dirty, they must be replaced promptly. The function of the air filter is to filter the air before it enters the cylinder, removing impurities, dust, sand, and other foreign particles.

What Causes the Reverse Radar to Keep Beeping?

Something is stuck on the reverse radar probe, blocking the signal; Solution: Check if there is any obstruction on the radar holes at the rear of the vehicle. 2. The rear wiper water pipe is leaking or water has seeped into the reverse radar system; Solution: Seal the leak (or replace the pipe) and drain any accumulated water in the radar system. 3. The radar ultrasonic signal is faulty, causing false alarms; Solution: Restart the engine, drive the vehicle to an open area, and try reversing again to observe the effect.

What to Do When the Car Side Skirt is Dented?

The solutions for a dented car side skirt are as follows: 1. First, determine the material of the side skirt—whether it is plastic or metal; 2. For metal materials: There is usually a granular coating on the surface. In this case, you need to take it to a repair shop for panel beating and repainting. 3. For plastic materials: If the dent is not severe, you can carefully tap it with a small hammer wrapped in a towel to restore its shape, as plastic materials have some elasticity; if the damage is significant, it should be taken to a professional mechanic for repair and repainting to restore its appearance.

Does the Geely Binyue have an engine anti-theft function?

Geely Binyue is equipped with an electronic engine anti-theft function. Introduction to Geely Binyue: The Geely Binyue is a representative model for the younger generation, a high-value, high-quality, and high-performance 'Chinese hot hatch' tailored specifically for young people, offering more personality, purity, and greater mechanical fun. The Geely Binyue is built on the BMA architecture and is powered by the G-Power260T (1.5TD) high-efficiency engine. It delivers a maximum power of 177ps/5500rpm and a peak torque of 255N/1500-4000rpm, surpassing the performance of a 2.5L naturally aspirated engine. It accelerates from 0-100km/h in just 7.9 seconds, brakes from 100km/h in 36.5m, and has a fuel consumption of only 6.3L per 100km, meeting the China VI-b emission standards. It is the most powerful 1.5TD engine in China. Introduction to the vehicle's engine anti-theft system: An anti-theft transponder is embedded in the car key. When the key is inserted into the ignition switch lock cylinder and turned to the 'ON' position, the electronic anti-theft ECU communicates with the key via radio frequency. If the key is confirmed as valid, the anti-theft ECU will perform a password verification with the engine ECU. If the password verification is correct, the engine will be allowed to start.
