How to recharge AC on 1996 suburban?

To recharge the AC on a 1996 Chevrolet Suburban, first, locate the low-pressure service port, typically found on the larger diameter aluminum line. Attach a recharge kit with R-134a refrigerant to the port, ensuring the can is upright while charging. Start the engine and turn the AC to max cool; then, slowly open the valve on the refrigerant can while monitoring the pressure gauge. Once the system reaches the recommended pressure, disconnect the can and check for any leaks.
