Where is the fuse box for cigarette lighter on Chevy Malibu 2005 classic?

The fuse for the cigarette lighter (or power outlet) in a 2005 Chevy Malibu Classic is located in the underhood fuse block. It's not in the interior fuse panel. You'll need to open the hood to access it.

The exact fuse number may vary slightly depending on options and trim level, but it's usually clearly labeled in the fuse block cover diagram. Check that diagram to find the fuse designated for the power outlet or cigarette lighter.
