How to replace the A/C Hose liquid line on those with RPO Code LHD, LA3, LY9 on Cadillac CTS?

A vehicle with rpo code lhd, la3, ly9 requires the technician to recover refrigerant and remove the air cleaner before liquid line repair. Unplug the electrical connector of the a/c high pressure switch before removing its screw. There are two small openings on the a/c quick joint which you can reach using the a/c quick joint tool (J 45689) along with its probe end while keeping the body of the tool parallel to the a/c line. Separate the evaporator fitting from the strut tower retaining clip through the use of the 45689 j tool before breaking it from the evaporator. Start installation by removing the evaporator inlet pipe which is attached to the vehicle. Applying refrigerant oil to new o-rings should be followed by placing the liquid line into the vehicle while fitting it into its bracket on the strut tower. Fasten the evaporator line using the a/c quick connect clamp by squeezing it until the tool clicks into place. Use a finger to verify the liquid line clamp stays secure before fastening the line to the condenser where the screw must be tightened to 9.8 n.m (87 lb in). Repeat the process of attaching another a/c quick connect clamp by pulling the liquid line to verify complete connection. After reconnecting the high pressure switch electrical connector to its switch, reinstall the air cleaner assembly then perform an evacuation and recharging of the refrigeration system. Test the fittings of repaired components or those that received reinstallation with a halogen leak detector (J 39400-A).
