i have a Chevrolet lacetti i have been trying to use the cigarette lighter to charge things like my phone and sat NAV but it doesn't seem to working i have also tried different adapters but still not charging. wondering what it could be like a fuse or something and if so whats the fuse number?

 

You don't say the year of the car so that makes it harder. The Lacetti is made by Daewoo. I found 1 schematic that says it is 7. It would just be better to check them all is it only takes a few minutes.
