What are the reasons for insufficient cooling in a car's air conditioning system?

[VonAbel]

The following are the reasons for insufficient cooling in a car's air conditioning system: 1. Lack of refrigerant (Freon): This is a normal situation, but it should be relatively rare. Since refrigerant is not a consumable item, it won't deplete on its own unless the vehicle has been involved in a severe rear-end collision or had its AC piping components dismantled, affecting the sealing integrity. 2. Poor heat dissipation: The radiator and condenser are crucial heat dissipation components in a vehicle. If they become too dirty, it can lead to poor heat dissipation, which not only causes engine overheating but also directly impacts the cooling efficiency of the air conditioning system. 3. Dirty air filter: The cabin air filter's function is to prevent external dust from entering the vehicle interior. Over time, the filter can accumulate dirt, develop odors, or even become clogged.
