Thank you for writing into AskPatty, you have high side (red) and low side (blue) smaller of the two ports. The low side can be located off the condenser side. You may need to replace your a/c clutch, orfice tube, and condenser. If there is ever a need to refill the freon gas in your a/c system, there is a leak, as this is a closed loop system.
