How do you replace 1997 Mitsubishi mirage expansion valve?

To replace the expansion valve on a 1997 Mitsubishi Mirage, first, ensure the vehicle is off and the AC system is discharged to prevent refrigerant release. Next, access the expansion valve, usually located near the evaporator core inside the dashboard. Disconnect the refrigerant lines and electrical connectors, then unbolt the old valve and replace it with the new one. Finally, reassemble everything, recharge the AC system with refrigerant, and check for leaks and proper operation.
