The compressor is called the heart of the air conditioning system. It pumps the refrigerant throughout the system. It also acts as a junction which divides the high-pressure and low-pressure sides of the system. The A/C compressor pulls the refrigerant gas from the evaporator in the low pressure side, compresses at a high temperature and sends it to the condenser. The A/C compressor is driven by a belt attached to the engine.
The A/C system in your GMC vehicle should be maintained at regular intervals to protect it and avoid damages.
