The A/C Compressor in your Cadillac is actually a mechanical pump powered by a drive belt connected to the engine's crankshaft. It is one of the most important components in the air conditioning system. The main responsibility of the A/C compressor 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 A/C compressor draws the refrigerant gas from the evaporator in the low pressure side and compresses and sends it to the condenser in the high pressure side.
The refrigerant vapor is then cooled and changed into liquid by the condenser. The A/C compressor and the condenser are two of the most vital pieces in the air conditioning system. If you think your A/C system is acting out of ordinary, you need to check the issue as soon as possible. If you do not, it could damage other parts in your air conditioning system.
