How to service the A/C Expansion Valve in an air conditioning system on 2004 Lincoln LS?

Service of the A/C expansion valve requires starting with the removal of the evaporator core. You should remove components starting with the pre-defined sequence. The air conditioning system repair requires replacement of a new receiver drier only in cases where physical evidence reveals fouling from a failed A/C compressor or receiver drier damage. A thorough check of the disconnected A/C fittings must occur after their reinstallation with new O-ring seals that received PAG oil lubrication. An upside down version of the removal process will serve for installation.
