How do you charge AC in 2003 Oldsmobile silhouette?

To charge the AC in a 2003 Oldsmobile Silhouette, first ensure the vehicle is running and the AC is set to the maximum cool setting. Locate the low-pressure service port, typically found on the larger aluminum line running from the compressor. Connect the refrigerant can's hose to the port, following the manufacturer's instructions on the can. Start adding refrigerant slowly, monitoring the pressure gauge to avoid overcharging, and check for cold air from the vents once the desired pressure is reached.
