that fuse is in the interior fuse box under your driver's side dash panel. The fuse is in the middle row of the three horizontal rows of fuses. It is a 15A (15 amp) fuse; I think it is blue in color but I may be wrong on that. The fuse is the third fuse in from the right (passenger side). There should be a label on the inside of the fuse box cover that says something like "accy"there is a fuse box under the hood as well. It has a black cover on it and it should be about 3" by 5"; it is usually on the passenger side back of the engine compartment but it may be in the driver's side front. That box has a list of fuses on th underside of the lid or stamped into the top of the plastic. There should be spare fuses in that box that you can use to replace the cigarette lighter fuse. The label for that fuse box will identify which fuses are 'spare' and you want the 15A fuse.hope that helps。
