What are the reasons for the truck air conditioner not cooling?

[VanMaddox]

Here are the reasons why a truck's air conditioner may not be cooling: 1. Accumulation of impurities in the condenser, resulting in poor heat dissipation; 2. Dust buildup in the air filter, leading to poor ventilation; 3. Damage to pipelines and connecting components, causing refrigerant leakage; 4. Compressor failure; 5. Expansion valve malfunction. Here are the solutions for a truck's air conditioner not cooling: 1. Check if the refrigerant is insufficient. If it is, simply go to a repair station to add refrigerant; 2. Check if the air filter is clogged with dust, and replace it if necessary; 3. Check if the condenser has accumulated impurities. Most impurities on the condenser can be cleaned with an air gun or water gun during car washing; 4. Check if the compressor is operating or damaged. If the compressor is damaged, it needs to be repaired or replaced.
