Not sure if this is the same connector BangerStanger is talking about, but in mine there is a connector that was unhooked next to the Ebrake, right beneath the center console storage piece. If it isn't disconnected, there isn't a coin in there, the fuse is good, you might have some other kind of electrical short running between the fuse and aux adapter.
If your electrical seat isn't working either (which is on the same fuse) more than likely a short.
A note though, the cigarette lighter only functions as a lighter, not as a 12v aux for accessories.
