on the weekend my son found that the rear cigarette lighter does not go ( huge problem the nitendo loader's diet did not go !! ) .
Error 1 : No backup inside !!??

Error 2 : Short circuit, as a cylindrical metal piece was stuck in the ignition (from a plug the front part).
Now my question:
According to the service booklet, on security site 21 a 25 A fuse belongs in, occupied with cigarette lighter and window lifter found doors!
But my window lifters have all worked, front and back !!
Also otherwise all electrical consumers have worked !
What else is attached to this fuse that it must be secured with 25 A?
