The fuse for the cigarette lighter (or power outlet) in a 2001 Oldsmobile Alero is typically located in the
underhood fuse box. However, there's no single definitive location across all Aleros. The specific fuse location and its amperage rating are found in your
owner's manual. The manual should have a fuse box diagram clearly showing which fuse corresponds to the power outlet.
Without your owner's manual, searching online for a "2001 Oldsmobile Alero fuse box diagram" might yield results with images showing the fuse layout, but proceed with caution and double-check against your manual if possible to be absolutely certain.
