Where do you load freon into the AC system of a 1997 Pontiac Grand Am?

The low-pressure refrigerant port is where you add freon to a 1997 Pontiac Grand Am's AC system. It's usually a service port with a cap, often colored blue. However, locating the exact position requires consulting your vehicle's repair manual or a diagram specific to that year and model. The location can vary slightly between years and even trim levels.

It's extremely important to note: Adding refrigerant yourself without proper knowledge and equipment is dangerous and can damage your AC system. Freon is under high pressure and can cause serious injury if handled incorrectly. You also need to know if there's a leak; simply adding refrigerant won't fix a leak and is a waste of money. It's best to have a qualified mechanic diagnose and service your AC system.
