The low-pressure AC port on a 1994 Jeep Grand Cherokee is typically located on the dryer/accumulator. This is a cylindrical canister usually found near the compressor, often on the driver's side of the engine compartment. The low-pressure port is usually smaller than the high-pressure port and will be capped. It's often colored blue.
