The A/C Compressor is a mechanical pump which is powered by a drive belt connected to the engine's crankshaft. Its main job is to supply and regulate the flow of refrigerant throughout the system. The A/C system has a high pressure side and a low pressure side which are defined as discharge and suction. The compressor draws the refrigerant gas from the evaporator in the low pressure side, compresses at a high temperature and sends it to the condenser.
The refrigerant vapor is then cooled and changed into liquid by the condenser. The A/C compressor and the condenser must work together in order for your A/C system to work properly. If you find any problems with your Buick A/C compressor, then you have to replace it with a quality part as soon as possible.
