Hi Bridget Bryant,
Can you be a little more descriptive as to what the issue is? When you say the AC reading is retard on low side, do you mean the low side AC is too low when the compressor comes on? If so, what is the pressure reading with the engine running and the compressor on and off? Also, do you have a dual gauge set that you can get the high side as well?
