How do you recharge the ac on a 2001 Malibu?

To recharge the AC on a 2001 Chevy Malibu, first ensure the engine is off and locate the low-pressure service port, typically found near the accumulator. Attach a refrigerant can with a recharge hose to the port, and start the engine with the AC set to maximum. Follow the instructions on the refrigerant can, usually involving shaking it and pressing the trigger to release the refrigerant until the system reaches the proper pressure. Monitor the pressure gauge and avoid overcharging, then disconnect the hose and replace the service port cap.
