I have a 1992 Honda Accord LX. After solving a long list of problems with this car, I now face a new problem: the 15 Amp fuse for the interior lights blows out when I turn the key to the ON position. Although having no interior lights is annoying, I could live with the problem except that more electrical features also rely on this fuse: the forward upper turn indicators and orange running lamps, the rear defroster, and the windshield wiper (only when using the sprayers). I have checked the wiring harnesses under the dash as best I could, but I haven't seen anything that looks bad. I have been unable to ascertain why this problem has arisen, considering I haven't done anything to any component running through this fuse. All interior lights are factory rated, the 30A fuse (the main fuse) for the rear defroster appears intact, and no other fuses are blowing out. All components will work fine while the key is off. This is very frustrating (and a bit illegal because only 2 of the 4 front turn indicators work now). Any help anyone could offer would be great.

Thanks,

Have you tried using a higher resistance fuse? It seems as though there are a lot of circuts running to that specific fuse, try using a 25 or 30 amp fuse, since there is that many circuts running to that one fuse, a 15 amp may not be enough. Try this, if it doesn't work, it won't hurt anything, if it does blow a higher amped fuse, the problem lies somewhere within the wires running through that circuit. If it does blow a higher amped fuse, look for junk wires, one of the wires may possibly be in contact with something it shouldn't be. Hopefully that will work, Good Luck.

The problem was solved. Surprisingly, the cigarette lighter was the problem. For aesthetics, I put the cigarette lighter in the socket. Due to a wiring fault with the cigarette lighter, this caused a short which blew the fuse. All the electronics that were connected to that fuse failed as a result. Funny how seemingly unrelated things can cause such a problem.
