I have a 91 4Runner and as of a few days ago the the taillights, license plate, driving, and dash lights won't turn on. I have changed the fuse in the fuse box, but the second I turn the lights on the fuse blows. My turn signals and headlights still work normally as does my clock and radio. Some people have told me that I could have a bad ground on the circuit. Any help fixing this problem would be great. I got pulled over the other night and thankfully the cop was cool and let me go, with shorter days I need to get this fixed ASAP.

Welcome to Yotatech

A "bad" ground would just make them not work (but not all those you listed as some have different grounds). A short circuit will blow the fuse.

So, you are looking for a pinched wire or something like that. Does the rig have any body damage? Does it have a trailer hitch with wiring? Those are the first places to look.

I would agree...sounds like you have a trailer hitch wiring harness that is shorting out and blowing the fuse.

I do have it wired for a trailer hitch which was done almost 2 years ago. I can't think that could be it as nothing has happened it that area. However I will give that a look today. Thanks

That same thing happened to me a few months ago. Turned out it was just a burnt out taillight. I would look through all of your external lights first for any that look burnt out.

i had the same issue....the line going to my licence plate holder had a wire that just got cut in half....look under the passanger side bumper and look at the wires....or your tow wireing, wire's might be showing or touching the metal somewhere.....well these were my issue's....hope it helps
