The air conditioner compressor has two fittings. You can add refrigerant to the low port fitting. The air conditioner compressor can be found on the right hand side of the engine near the front.
You don't. The 2000 Saturn refrigerant is not Freon R12 it contains R134a. Add it at the Low pressure port. You have a leak or it would not be necessary to add refrigerant. It is illegal to add refrigerant to a system with a leak without first repairing the leak. Take it to a professional and have the leak fixed.
You add the refrigerant through the low side service port.

You add refrigerant at the low pressure port but you do not add Freon. You add R134/134a. If you are having to add refrigerant then you have a leak that needs to be repaired first.
The refrigerant needs to be added on the low pressure side of the compressor. this is located under the front of the vehicle by the bottom of the radiator. the line has a fitting which should have a blue cap on it. that's where you add the freon.
To add refrigerant to your 2004 Saturn Ion, locate the low-pressure service port, which is typically found on the larger diameter aluminum line between the compressor and the evaporator. Remove the cap, attach the refrigerant can’s hose to the port, and then follow the instructions on the refrigerant can to add the refrigerant. Make sure the air conditioning system is running while you do this for accurate readings. Always check for leaks and ensure you’re using the correct type of refrigerant, usually R-134a for this model.
you dont just let it blow up
well unless you have the right equipment, the dealer.
To add R134a to a 2002 Saturn SL, first ensure the engine is off and the AC is set to the maximum cool setting. Locate the low-pressure service port, which is typically near the AC compressor; it has a larger diameter than the high-pressure port. Attach the R134a refrigerant can to the low-pressure port, following the manufacturer's instructions, and open the can while the engine is running and the AC is on to allow the refrigerant to flow into the system. Monitor the pressure and avoid overfilling, as this can damage the AC system.
There should be a fitting with a screw top on it somewhere in the AC hose in the engine compartment. Use R134A, not R12

To add refrigerant to your AC unit, you will need to locate the service valve on the unit, connect a refrigerant charging hose to the valve, and slowly add the refrigerant following the manufacturer's instructions. It is important to be cautious and follow safety guidelines when handling refrigerant.
