How to service and repair the rear auxiliary evaporator outlet and inlet A/C Hose on 2004 Mercury Mountaineer?

Start the repair of rear auxiliary evaporator outlet and inlet line by positioning the vehicle on a hoist while keeping the gear selector in NEUTRAL position. Recover all refrigerant and then remove the spare tire as the first step. Service operators must keep to the prescribed procedure in disassembling required components. The refrigerant system O-ring seals must be lubricated solely with Refrigerant Compressor Oil F73Z-19577-AA (Motorcraft YN-9-A) while PAG Refrigerant Compressor Oil F7AZ-19589-DA (Motorcraft YN-12-C) or equivalent WSH-M1C231-B version from Ford serves as the A/C compressor lubricant. The air conditioning system requires an accumulator replacement only when physical damage to the component or contaminant evidence from a broken A/C compressor becomes apparent. Cap off and connect A/C fittings only after installation of new O-ring seals which received mineral oil lubrication. Implement the opposite steps for installation and apply proper quantities of clean PAG oil to the refrigerant system. Evacuate the system after which you should perform a leak test and then proceed with the refrigerant charge.
