How to service the A/C Expansion Valve in the auxiliary climate control system on 2004 Lincoln Navigator?

Beginning the service of the thermostatic expansion valve within the auxiliary climate control system requires refrigerant recovery. The right-hand quarter trim panel needs removal while disconnecting fittings before removing the thermostatic expansion valve from its position but discarding the O-ring seals. Installing the system should begin with the opposite steps of removal and require fresh O-ring seals treated with clean PAG oil. Users should add proper quantities of clean PAG oil to the refrigerant system lubrication. The refrigerant system needs evacuation and leaking with final charging steps to complete the procedure.
