Buzzing when air conditioning is switched off

If the engine is idling, there may be buzzing noises in the engine compartment when the air conditioning is switched off. These can be caused by the air conditioning compressor.  

Before replacing the compressor, check the battery voltage, the compressor power supply and the correct refrigerant quantity or system pressures.
