How do you charge a 1997 Toyota t 100 air conditioner?

To charge the air conditioner in a 1997 Toyota T100, first, locate the low-pressure service port, which is typically on the larger diameter aluminum line. Start the engine and turn the AC to the maximum setting. Connect a refrigerant canister to the low-pressure port and follow the manufacturer's instructions to add refrigerant, making sure to check the pressure readings on the gauge to avoid overcharging. Always ensure proper safety measures are taken, and consider consulting a professional if you're unsure.
