How do you recharge AC in 99 Safari Van?

To recharge the AC in a 1999 Safari Van, first, locate the low-pressure service port, typically found on the larger diameter aluminum line. Attach a refrigerant gauge and recharge kit to the port, ensuring the engine is running and the AC is set to maximum. Add the appropriate refrigerant, usually R-134a, until the pressure readings are within the manufacturer's recommended range. Monitor the system to avoid overcharging and ensure optimal performance.
