What are the symptoms of a failing A/C compressor in a Toyota Prius?

If the A/C is not cooling properly, how can owners determine if the compressor is the issue? Are there specific warning signs, such as strange noises, weak airflow, o r fluctuating cooling?

Signs of a failing A/C compressor can include:

Weak o r No Airflow: If the compressor isn’t working, the airflow might feel weak o r non-existent.
Unusual Noises: A failing compressor may produce rattling, grinding, o r squealing noises, indicating internal damage.
Fluctuating Temperature: If the compressor is malfunctioning, it can cause erratic cooling, with temperatures cycling between cold and warm.
Warm Air Blowing: The most obvious sign is warm air blowing from the A/C vents, indicating the system is not cooling properly.
