Rear

Rear A/C Evaporator:

The A/C evaporator for the rear heating-A/C system is located within the rear HVAC housing, behind the right quarter trim panel. 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 evaporator fins will only be conditioned when the A/C compressor is engaged and circulating refrigerant through the rear A/C evaporator.

The rear A/C evaporator tubes are connected and sealed to the rear A/C expansion valve by use of rubber O-rings and a tapping block.

The rear A/C evaporator can only be serviced by removing and disassembling the rear HVAC housing.

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.
