  A: Air conditioning Evaporator core replacement begins by extracting the thermal expansion valve (Expansion Block/Orifice Tube/Service and Repair/Air Conditioning Evaporator Thermal Expansion Valve Replacement), followed by unscrewing the hvac module case together with its retaining clips. Disconnect the hvac module wiring harness from the rh temperature actuator then set it aside before you move on to disconnect, reposition and reconnect the Evaporator core temperature sensor connector. Distinctly separate the hvac module from other components and then extracted the combination of Evaporator core and thermistor unit. Refrigerant oil should be added to the Evaporator core according to specifications and capacity guidelines then new Evaporator core seals should be installed followed by attaching the thermistor. Install the Evaporator core while connecting both halves of the hvac module case. The process involves securing vaporator core temperature sensor connector along with hvac module wiring harness to the rh temperature actuator. After securing the hvac module with retainer clips according to fastener caution (Service Precautions/Vehicle Damage Warnings/Fastener Caution) the technician installs case screws and tightens them to 1 nm (9 lb in).
