First, you need to remove the HVAC module assembly and remove the insulation from the thermal expansion valve (TXV). Then, please remove the HVAC line clamp screw, the HVAC line clamp, the TXV to evaporator bolts, the TXV line bracket, and the TXV from the evaporator core. You also need to separate the TXV from the A/C lines and remove the TXV, the screws that hold the case together, and the clips that hold the case together. Finally, you should disconnect the thermistor electrical connector, separate the HVAC module, and remove the thermistor and the evaporator core.

First, you need to remove the HVAC module, the floor front air outlet duct, and the heater core. Then, please disconnect the electrical connector from the left air temperature actuator, and the evaporator sensor and reposition. Finally, you should remove the 10 HVAC case screws and separate the case to expose the evaporator temperature sensor.

The recommended torque is 1Nm(8 lb in).

You should install the evaporator temperature sensor in the original location within the core and ensure all seals and gaskets are in position upon installation.
