7.
Remove the nut that secures the underbody A/C lines to the rear evaporator tapping plate (Figure 2).
8.
Disconnect the underbody A/C lines from the evaporator tapping plate.
NOTE:
The A/C line mounting block may not come loose after removing the retaining nut due to corrosion between the mounting block and the
retaining stud. Do not use excessive force to attempt to remove the mounting block from the evaporator. Evaporator damage may occur. Using
an air chisel with a flat nose bit, gently pull down on the A/C lines and then lightly rap on the end of the stud with the bit of the air chisel
(Figure 3).
