HVAC Systems (Service Information): Plumbing: Evaporator-A/C: Description
NOTE:
LHD model shown in illustration. RHD model similar.
The A/C evaporator (1) for the heating-A/C system is mounted within the HVAC housing, which is located behind the instrument panel. The A/C evaporator and it's insulator are positioned in the HVAC housing so that all air entering the housing must pass over the evaporator fins before it is distributed through the 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 A/C evaporator.
The A/C evaporator tubes (2) are connected and sealed to the accumulator tubes by use of rubber O-rings and a tapping block (3).
The A/C evaporator can only be serviced by removing and disassembling the HVAC housing assembly.
