How do you recharge AC on 2004 Chevy Monte Carlo?

To recharge the AC on a 2004 Chevy Monte Carlo, first locate the low-pressure service port, typically found near the accumulator or on the larger tubing between the compressor and the evaporator. Attach the refrigerant canister to the port and follow the manufacturer's instructions, usually involving shaking the canister and turning the valve to allow refrigerant to flow into the system. Monitor the pressure gauge to ensure it reaches the appropriate level, and avoid overcharging. Always wear safety goggles and gloves while working with refrigerant.
