The A/C compressor is one of those parts on your car that you pay no attention to, until it fails. The A/C compressor is the heart of the air conditioning system, without it you have no A/C. Though the compressor can fail for a multitude of reasons, most commonly the two parts that will fail are the compressor motor its self or the clutch that engages the compressor to run will fail. Some makes of compressors will allow you to change the clutch alone, others you cannot remove the clutch or the clutch is not available by its self so you have to replace the whole compressor. When you have to replace yours, trust Griffiths A/C compressors.
