Section 18 (HVAC System - Manual): Operation: Condenser
WARNING: This page is about a different car, the 2001 Chevrolet Malibu and 2000 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
Condenser (located in front of radiator) is made up of coils attached with fins to transfer heat. Air passing through condenser cools high-pressure, high-temperature refrigerant vapor, causing it to condense to a liquid.
