What are the reasons why a car air conditioner won't turn on?

Car air conditioner won't turn on due to: 1. Failure of the car air conditioning compressor; 2. Malfunction in the car's electronic system; 3. Damaged air conditioning button; 4. Dead battery. The components of a car air conditioner are: compressor, condenser, evaporator, liquid storage dryer, expansion valve. The function of a car air conditioner is to regulate the temperature, humidity, air cleanliness, and air flow inside the car cabin. The working principle of car air conditioner heating is: When the car's engine water temperature becomes too high, the refrigerant gas enters the condenser, where pressure and temperature decrease, the refrigerant gas condenses into liquid, and heat is discharged.
It's really annoying when the air conditioning won't turn on. I've encountered this issue before when driving. Here are possible causes: First, it might be a blown fuse - try finding and replacing the corresponding one in the front fuse box. Second, if the refrigerant has leaked or is insufficient, the compressor won't work, and you'll need to visit a shop for a refill. Third, the fan blades might be stuck or broken, preventing airflow - check if the fan under the hood is spinning. Alternatively, there could be poor contact with the control buttons or wiring - try pressing them gently to see if there's any response. Finally, the system might be too old and clogged. When checking yourself, don't rush to dismantle anything; start with simple solutions first. Remember to maintain your AC regularly, such as cleaning the filter every six months, to minimize problems.
