Rear

The rear A/C evaporator (1) is located within the rear HVAC housing (2), behind the right interior quarter panel trim. The rear A/C evaporator is positioned in the rear HVAC housing so that all air entering the housing must pass over the evaporator fins before it is distributed through the rear heating-A/C system ducts and outlets. However, air passing over the rear evaporator fins will only be conditioned when the A/C compressor is engaged and circulating refrigerant through the A/C evaporator.

Refrigerant enters the rear A/C evaporator from the rear A/C expansion valve as a low-temperature, low-pressure mixture of liquid and gas. As air flows over the fins of the rear A/C evaporator, the humidity in the air condenses on the fins, and the heat from the air is absorbed by the refrigerant. Heat absorption causes the refrigerant to boil and vaporize. The refrigerant becomes a low-pressure gas when it leaves the rear A/C evaporator.

The rear A/C evaporator cannot be repaired and, if faulty or damaged, it must be replaced.
