How do you recharge the ac on a 1999 G20 Infiniti?

To recharge the AC on a 1999 Infiniti G20, first, locate the low-pressure service port, typically found on the larger AC line. Attach a refrigerant can with a gauge to the port, ensuring the can is upright. Start the engine and turn the AC to the maximum setting, then slowly release the refrigerant into the system while monitoring the pressure gauge. Once the proper pressure is reached, disconnect the can and replace the service port cap.
