* Air Conditioning (A/C) Compressor: This is usually located on the engine, often driven by a belt. Its exact position varies by car make and model, but it's frequently near the front of the engine, somewhere easily accessible for belt replacement and maintenance.
* Air Suspension Compressor: This is part of the air suspension system and is typically located somewhere in the undercarriage of the vehicle, often in a protected area near the rear axle or in a wheel well. Its location is less standardized than the A/C compressor.
Without knowing whether you're referring to the A/C or air suspension compressor, it's impossible to give a more precise location.
