Where is lighter fuse located in a 96 Cadillac STS?

The lighter fuse in a 1996 Cadillac STS is typically located in the underhood fuse block. However, it's not always labeled "lighter." It might be labeled as "Power Outlet," "Accessory," or something similar.

You'll need to consult your owner's manual for the exact location and fuse rating. The owner's manual will have a fuse panel diagram showing the location of each fuse.

If you don't have the owner's manual, you can often find a digital version online by searching "[Year] Cadillac STS Owner's Manual PDF".
