What are the reasons for a car's air conditioning not cooling?

The reasons for a car's air conditioning not cooling are: 1. Lack of refrigerant: Car air conditioning systems generally require refrigerant replenishment every 2 to 3 years, with most losses occurring due to leaks. If the air conditioning stops cooling after refrigerant refill and then fails again after some time, the system should be checked for damage; 2. Dirty condenser: When the condenser is blocked by debris, it can cause engine overheating or air conditioning failure; 3. Damaged throttle valve or expansion valve: Malfunctions in these components will directly result in air conditioning failure; 4. Worn or loose belt; 5. Damaged air conditioning flap.
My car's AC doesn't cool well in summer, which is really annoying. The most common reasons are insufficient refrigerant or leaks, possibly due to aging pipes or loose connections. A broken compressor could also be the culprit - that's the heart of the AC system, and once it fails, cooling stops. I usually check the fuse box myself; if a fuse is blown, the AC won't turn on, and replacing it might solve the problem. Additionally, a severely clogged cabin air filter can obstruct airflow - cleaning or replacing it can help. Another issue could be the condenser fan malfunctioning; if the fan doesn't spin, heat can't dissipate properly, leading to poor cooling. I must remind everyone not to overlook these small issues, especially during hot weather when driving safety comes first. Regular professional maintenance of the AC system is recommended to avoid uncomfortable breakdowns. In short, checking these points can save a lot of trouble.
