To find it, you'll need to locate the AC system's service ports. These are typically found on one of the AC lines near the compressor, condenser or evaporator. They are usually capped and sometimes colored (usually blue for low pressure, red for high pressure).
However, I strongly advise against attempting this yourself. A/C systems require specialized tools and knowledge to properly charge with the correct refrigerant type and amount. Incorrect charging can damage the system and potentially lead to injury.
Recommendation: Take your vehicle to a qualified mechanic or an automotive air conditioning specialist for proper refrigerant recharge. They have the necessary equipment and expertise to do the job safely and effectively. Trying to do it yourself could be costly in the long run if something goes wrong.
