I have Hyundai Grandeur(Azera) 2007, which has not working front cigarette lighter. I tried to find a fuse which is responsible for front cigarette lighter in two fuse boxes but didn't find any good description for it. Instead of it I just checked all fuses in two fuse boxes. All is ok.
Maybe this car has the third fuse box?

 

Or maybe the socket is just bad. Check for power at the wires attached to the outlet first.

 

How to unmount this outlet?
