This bulletin applies to 2011 Jeep Grand Cherokee vehicles. The A/C system may be inoperative or may lose charge. This may be caused by a weld issue inside the service port on the liquid side. This condition is difficult to diagnose since the A/C gauge set (when connected) will cover-up the leak point.
1. Operate the A/C system. Does the compressor engage? If yes, continue with Step 2. If no, add refrigerant in the appropriate volume and continue with Step 2.
2. Remove the cap from the liquid line service port. Using a liquid leak detector (SNOOP or equivalent), check inside the service port for leaking refrigerant. If bubbles are seen coming from the inside of the service port, replace the liquid line.
