Why is the car air conditioner not cooling in summer?

[Lola]

Here is the relevant introduction about the car air conditioner not cooling in summer: 1. Lack of refrigerant: In fact, even if the air conditioner is tightly sealed, it still cannot prevent the refrigerant from escaping, plus there may be minor leaks in the air conditioning pipes or condenser. Most of the refrigerant loss is due to leakage. If the car's air conditioner is not working well and starts to malfunction again after refilling the refrigerant for a while, then attention should be paid. Generally, when this happens, it often means a costly repair is needed. If the condenser is leaking, it needs to be replaced. The method to check for leaks is also quite troublesome, usually involving adding fluorescent agent to the refrigerant oil and using special glasses to inspect. 2. Damaged air conditioning flap: The failure of the air conditioning flap motor is relatively rare, but it has occurred. If the flap motor has a problem, it is troublesome. The flap motor is usually located in the lower middle part of the instrument panel and serves as the main switch for the air conditioning vents. If it is broken, it means the switch is faulty. Even if the air conditioner can cool, the cold air can only come out through gaps, which is like drinking poison to quench thirst.
