Description And Operation: Description
The rear A/C evaporator (1) is located within the Heating, Ventilation and Air Conditioning, Rear (HVACR) housing, behind the right interior quarter panel trim. The rear A/C evaporator is positioned in the HVACR housing so that all air entering the housing must pass over the evaporator fins before it is distributed through the HVACR 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.
The A/C expansion valve is connected and sealed to the A/C evaporator tubes (2) by use of rubber O-ring seals (3) and a tapping plate (4).
The rear A/C evaporator can only be serviced by removing and disassembling the HVACR housing.
