WARNING: This page is about a different car, the 1997 Suzuki Esteem. However, it is still accessible from the selected car via links, so may be relevant.
The compressor compresses low pressure refrigerant vapor into high pressure, high temperature vapor. When magnetic clutch is activated, compressor continuously pumps R-134a refrigerant and PAG refrigerant oil through A/C system.
