Understanding Your Car’s AC System
Before diving into troubleshooting, it’s helpful to understand the basic components of your car’s AC system. The key players are the compressor, condenser, evaporator, expansion valve or orifice tube, and refrigerant. These work together to remove heat and humidity from the air inside your car.
Common Causes of a Car AC Not Cooling
Low Refrigerant Levels
One of the most frequent reasons for a car AC not cooling is low refrigerant. A leak in the system can cause the refrigerant level to drop, hindering its ability to cool the air. Signs of a leak include weak airflow and a hissing sound from the AC system.

Faulty Compressor
The compressor is the heart of the AC system, responsible for circulating the refrigerant. A failing compressor will result in little to no cold air. Clues that the compressor might be the culprit include unusual noises coming from the engine compartment when the AC is on or a noticeable decrease in cooling performance.
Blocked or Damaged Condenser
The condenser looks like a radiator and sits at the front of your vehicle. Its job is to release heat absorbed by the refrigerant. A blocked condenser restricts airflow, reducing cooling efficiency. Damage to the condenser fins can also impede heat transfer.

Electrical Issues
Electrical problems, such as a blown fuse, faulty relay, or damaged wiring, can disrupt the power supply to the AC components. This can lead to various problems, including the AC not turning on or not blowing cold air.
Blend Door Problems
The blend door controls the mix of hot and cold air entering the cabin. If the blend door is stuck or malfunctioning, it might be directing only hot air into the car, even if the AC system is working correctly.
