Where is the fuse for the lighter in a 2006 dts Cadillac?

In a 2006 Cadillac DTS, the fuse for the lighter is located in the fuse box under the rear seat. To access it, you'll need to remove the rear seat cushion, which can be done by lifting it up to expose the fuse panel. Look for the fuse labeled "CIG" or "Lighter" in the diagram on the fuse box cover. If the fuse is blown, replacing it should restore functionality to the lighter.
