How to Service the A/C Accumulator in the HVAC System on Mercury Mariner?

A proper servicing of the HVAC system suction accumulator begins with recovering refrigerant from the system. The evacuation begins with disconnecting the A/C cycling switch electrical connector while also handling the suction accumulator inlet and outlet fittings until you remove their O-ring seals. Unthread the two bracket securing nuts from the suction accumulator while you should tighten them to 8 Nm (71 lb-in) before reinstalling them. Perform installation by using new O-ring seals along with filling the refrigerant system with the correct amount of PAG oil. To install the suction accumulator on hybrid vehicles maintain it in upside orientation before performing the rotational installation. Evacuation and system leak testing should be followed by refrigerant system charging. Restoring the suction accumulator system requires new replacement only when mechanics observe contamination from a faulty A/C compressor or detect damaged existing accumulator components.
