What is the fuse number for the 12v adapter on my 2007 astra?

For a 2007 Astra, the fuse for the 12V adapter (often referred to as the cigarette lighter) is typically Fuse 15 in the interior fuse box. However, it's always best to consult the owner's manual for the specific fuse layout, as configurations can vary based on the model and region. If you're unsure, you can also visually inspect the fuse box for any blown fuses.
