How do you replace madza Miata ac expansion valve?

To replace the AC expansion valve in a Mazda Miata, first ensure the system is fully discharged to avoid refrigerant exposure. Remove the interior dashboard components to access the expansion valve, typically located near the evaporator. Disconnect the refrigerant lines and electrical connectors from the valve, then unbolt and remove the old valve. Install the new valve, reconnect the lines and electrical connectors, and reassemble the dashboard before recharging the AC system.
