How does one recharge air conditioner on 2000 Miata?

To recharge the air conditioning system on a 2000 Mazda Miata, first locate the low-pressure service port, which is typically found on the larger of the two refrigerant lines. Connect a compatible A/C recharge kit to this port, ensuring the can is upright. Start the engine and turn the A/C to the maximum setting, then slowly release the refrigerant into the system while monitoring the pressure gauge on the kit. Once the recommended pressure is reached, disconnect the kit and check for proper A/C function.
