The most common cause is a clogged cabin air filter. Here is some information about the cabin air filter: Function: It absorbs moisture, soot, ozone, odors, carbon oxides, SOCO2, and other substances from the air; it has strong and long-lasting moisture absorption capabilities. This prevents the car windows from fogging up, ensuring clear visibility for the driver and passengers and safe driving. It also provides fresh air to the cabin, preventing occupants from inhaling harmful gases and ensuring driving safety. Additionally, it effectively eliminates bacteria and odors. Replacement: How often you should replace the cabin air filter depends on your driving conditions. For general city use in a household car, it is recommended to replace it every six months or once a year.

This can affect the starting of the vehicle, so it's necessary to inspect and replace the battery promptly. Here are some additional details: 1. Before turning off the vehicle, make sure to roll up all the windows and turn off all electrical devices to protect the car battery.

What is the service life of a car?

Generally, the normal service life of a car is around 8-10 years. With proper maintenance, the service life can be extended further. Typically, private cars should be scrapped after 15 years of use or when the mileage reaches 600,000 kilometers. However, there are no mandatory scrapping regulations for non-commercial household private cars. As long as the vehicle meets the annual inspection standards, it can still be used normally. For commercial vehicles, the government will guide their scrapping once they reach the designated service life. The lifespan of a car is influenced by many factors, including wear and corrosion, dirt accumulation and deterioration, aging of non-metallic components such as rubber and plastic, material fatigue, deformation of parts or poor manufacturing quality, improper operation or misuse, incorrect maintenance, and traffic accidents. When using a car, owners should perform regular maintenance. A minor maintenance should be done every 5,000 kilometers, the front and rear wheels should be rotated every 30,000 kilometers, and the tires should be replaced every 50,000 kilometers. At the same time, driving habits should be as standardized as possible to prevent traffic accidents.
