How do you put a freon in 1993 geo storm?

To add freon to a 1993 Geo Storm, first ensure the air conditioning system is turned off and locate the low-pressure service port, typically found on the larger diameter A/C line. Use a refrigerant gauge and hose to connect the can of refrigerant to the port. Open the can and run the engine with the A/C on to allow the refrigerant to flow into the system. Monitor the pressure to avoid overfilling, and ensure the system is functioning properly afterward.
