The A/C compressor is one of those parts on your car that you pay no attention to, until it fails. While all of the parts in the air conditioning system are important, arguably the most important is the compressor, without it you wouldn't have air conditioning. The compressor can fail for many reasons; the most common two are either the actual compressor motor wears out or the clutch stops working. 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. If you are looking for a replacement, you can depend on Air Products A/C compressors.
