Rear Refrigerant Lines

REMOVAL
The rear refrigerant lines for the optional rear A/C system is serviced in four sections. The liquid line for the optional rear A/C system uses a spring-lock refrigerant line coupler which requires the use of a 3/8 inch quick-disconnect tool (part of Special Tool, A/C Line Disconnect Kit 7193).

WARNING: REVIEW THE WARNINGS AND CAUTIONS IN THE FRONT OF THIS SECTION BEFORE PERFORMING THE FOLLOWING OPERATION.

1. Recover the refrigerant from the refrigerant system.
2. Disconnect and isolate the battery negative cable.
3. Remove the interior trim panel from the right quarter panel.
4. Disconnect the fittings that secure the rear refrigerant lines to the sidewall refrigerant lines.
5. Remove the seals from the open liquid and suction line fittings and discard.
6. Install plugs in, or tape over the open liquid and suction line fittings.
7. Raise and support the vehicle.
8. Disconnect the fittings that secure the intermediate refrigerant lines to the rear refrigerant lines.
9. Remove the seals from the open liquid and suction line fittings and discard.
10. Install plugs in, or tape over the open liquid and suction line fittings.
11. Remove the propeller shaft.
12. Remove the seal from the right inner sidewall.
13. Carefully pull the rubber rear refrigerant lines out from the sidewall.
