The low-pressure port on the A/C system of a 2000 Pontiac Grand Am GT is typically located on the
accumulator/receiver drier. This is a cylindrical component often found near the firewall on the passenger side of the engine compartment. The port will be smaller than the high-pressure port and may be capped. Look for two ports – one larger (high pressure) and one smaller (low pressure) – on this component.
However, it's crucial to consult a repair manual specific to your 2000 Pontiac Grand Am GT. The exact location can vary slightly depending on the specific model and any aftermarket modifications. Using the wrong port can damage your A/C system. A repair manual will provide diagrams and specifications to ensure you identify the correct ports.
