I had the same problem with the cigarette lighter (powering a cell phone adaptor) but it was intermittent. I found out it wasn't not the fuse but the center mount post (the positive terminal) of the cigarette lighter itself was loosened I had just to be tightened. The tough part is accessing the lighter itself. I ended prying it out from the top, giving just enough access to get to the bolt underneath with a tiny pair of pliers.
