I have a 2005 Aveo LS. My cigarette lighter/accessory fuse is the top, left one on the driver's side of the dash. A visual inspection of a fuse is reliable for checking if a fuse is bad because you can see if it is blown. But what if the fuse is not blown? Can you say with certainty that it is good? Best to use a test lamp or a meter to see if current is running through the fuse.
If the lamp/meter shows that current is running through the fuse, you can then use the lamp/meter to see if current is reaching the cigarette/accessory outlets.
