The Compressor is one of the major components in your Buick Air Conditioning system which regulates and supplies the refrigerant in the system. It is considered the heart of the A/C system. It is a mechanical pump which is driven by a belt connected to the engine. The A/C compressor and the condenser must work together in order for your A/C system to operate properly. The condenser cools the refrigerant and changes it into liquid. If you find any difference in the working of the Buick A/C compressor, you need to replace it with a genuine part as early as possible.
