The fuse for the cigarette lighter socket on the 2010 Ford Fiesta is located inside the fuse box within the vehicle. Specifically, the fuse is found in the driver’s side glove compartment. To check the fuse after confirming that the socket is not working, you need to remove the entire compartment. The relevant fuse is numbered 6 and rated at 20 watts. Once you have removed the damaged fuse, insert a new one to restore proper function to the socket.
