Warning! Do not disconnect the components of the air conditioning system until it is discharged. See Precautions in Section General Description and Precautions - Air Conditioning System.
The only action that can be performed without discharging the system is to replace the compressor drive belt. For other problems, it is recommended to contact a Renault workshop or an air conditioning specialist.
If necessary, after removing the drive belt, the compressor can be disconnected and moved to the side without disconnecting the pipes carrying the refrigerant from it.
