On a 2005 Ford Focus ZX3, the gauge cluster lights fuse is located in the interior fuse panel, which is typically found under the dashboard on the driver's side. To access it, you may need to remove a cover or panel. The specific fuse for the gauge cluster lights is usually labeled in the fuse diagram, which can be found on the inside of the fuse box cover or in the owner's manual. Check the diagram to identify the correct fuse and ensure it is in good condition.
