The A/C system in a vehicle has many parts. The compressor is one of the major components which regulates and supplies the refrigerant in the system. It is considered the heart of the A/C system. It is basically 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 work correctly. The condenser then cools the refrigerant and changes it into liquid.
If the A/C compressor for your Buick is damaged it will also affect other parts in the vehicle, so it must be replaced as soon as possible.
