Where is the low side ac port on a 2003 Pontiac vibe?

The low-side AC port on a 2003 Pontiac Vibe is located on the dryer/accumulator. The dryer/accumulator is usually found near the front of the vehicle, on the passenger side of the engine compartment, often near the firewall. It's a cylindrical canister with fittings for the AC lines. The low-pressure port is typically smaller than the high-pressure port.

Important Note: However, the exact location might vary slightly depending on specific model variations. It's always best to consult a repair manual specific to your 2003 Pontiac Vibe's year and engine to confirm the precise location before attempting any AC work. Working with refrigerant requires special equipment and safety precautions. If you're not experienced with automotive AC systems, it's highly recommended to have a qualified mechanic perform any service or repair.
