How do you change cel bulb on 2008 Ford Fusion?

To change the CEL (check engine light) bulb on a 2008 Ford Fusion, first, ensure the vehicle is turned off and the key is removed from the ignition. Open the hood and disconnect the negative battery cable to prevent any electrical issues. Remove the instrument cluster by unscrewing the necessary screws and gently pulling it out. Replace the burnt-out bulb with a new one, reassemble the cluster, and reconnect the battery.
