Where is the refrigerant port on 97 Buick Skylark?

On a 1997 Buick Skylark, the refrigerant service ports are located on the air conditioning system. The low-pressure service port is typically found on the larger diameter aluminum line, near the compressor, while the high-pressure service port is on the smaller line. Both ports are usually covered with plastic caps, and it's important to identify them correctly before servicing the AC system. If you're unsure, consulting the vehicle's service manual can provide additional guidance.
