The fuse for the cigarette lighter in a 1998 Chevy Monte Carlo is typically found in the
underhood fuse block. However, there's no single definitive answer without looking at your owner's manual. The fuse box diagram in the manual will show you which fuse controls the power outlet (cigarette lighter).
The fuse itself might be labeled "Power Outlet," "Accessory," "Cigarette Lighter," or something similar. If you can't find it labeled directly, you might need to test the fuses with a multimeter to determine which one is providing power to the lighter.
