- Your car's air conditioning system is not blowing cold air. This is the most obvious sign that your AC compressor is not working properly. If the air coming out of your vents is warm or hot, it is likely that your compressor is not compressing the refrigerant properly.
- You hear a clicking or grinding noise when you turn on your air conditioning. This could be a sign that the compressor is seized or damaged.
- Your car's air conditioning system is leaking refrigerant. If you see a green or yellow fluid leaking from under your car, it is likely that your AC system is leaking refrigerant. This can cause the compressor to overheat and eventually fail.
- Your car's air conditioning system is not cooling your car down as well as it used to. If you notice that your car is not cooling down as quickly as it used to, it could be a sign that your AC compressor is not working properly.
If you are experiencing any of these symptoms, it is important to have your car's air conditioning system inspected by a qualified mechanic as soon as possible.
