The 2002 Chevy Impala's license plate light fuse is typically located in the
underhood fuse block, and it's usually labeled as
"Tail Lamps" or sometimes
"Back-Up Lamps". It's *not* a dedicated fuse just for the license plate light. The license plate light is part of the tail lamp circuit.
Important Note: Consult your owner's manual. The specific fuse number and location *might* vary slightly depending on your trim level and options. Your owner's manual will provide the most accurate information for your vehicle.
