How do you recharge air conditioner on Toyota 4 runner?

To recharge the air conditioning system on a Toyota 4Runner, first, locate the low-pressure service port, typically found on the larger of the two AC lines. Connect a recharge kit with refrigerant to this port, ensuring the can is upright. Start the engine and turn the AC to the maximum setting, then slowly release the refrigerant until the desired pressure is reached, monitoring the gauge on the kit. Always check for any leaks before and after recharging, and consult your owner's manual for specific refrigerant type and capacity.
