With Air ConditioningCAUTION Some 1992-93 and all 1994-95 air conditioned vehicles covered by this information are equipped with a new non-CFC (chlorofluorocarbon) refrigerant (R-134a). This new refrigerant is not available commercially in most areas, as it is usually illegal for do-it-yourselfers to service a vehicle with this refrigerant. If you have a Taurus or Sable that uses the new refrigerant, R-134a, the vehicle should be taken to a qualified technician for any repair requiring A/C system service.
It is necessary to remove the evaporator case in order to remove the heater core. Whenever an evaporator case is removed, it will be necessary to replace the suction accumulator/drier.
Do not rotate the steering column shaft.
Be sure to consult the laws in your area before beginning any procedure which requires servicing the air conditioning system. In some states, it is illegal to perform repairs involving refrigerant unless the work is done by a certified technician.
Some 1992-93 and all 1994-95 vehicles covered by this information are equipped with R-134a NOT R-12 refrigerant. These two refrigerants are NOT compatible. Using the incorrect refrigerant in an R-134a system will lead to compressor failure, refrigerant oil sludge and/or poor air conditioning system performance.
