Re: NEED HELP (electrical)

First off NEVER substitute a larger fuse in order to remedy a blowing fuse, you may end up with an electrical fire.
I believe what you are referring to are the parking lights.
To help troubleshoot, get yourself sealed been head light or any 12v bulb & socket plus a length of wire as needed to position the bulb in a convenient location. 18 gauge should be fine for troubleshooting. The bulb will save you some money from wasting fuses during the troubleshooting process & give you a visual indicator when you have located the short.
Now for the fun part. Remove the under dash trim panel & knee bolster. Remove the fuse that keeps blowing. Connect the bulb across the terminals of the fuse block where you removed the fuse, use the extra wire as needed so it will be visible while your head is under the dash & to keep the bulb from burning you or your interior. Turn your light switch to the parking light position. If you have a short, the bulb that you have connect across the fuse terminals will glow. Its brightness depends on how much the circuit is "shorted." The brighter it is the more it is shorted.
From your description, the bulb should be pretty bright. Now move the wiring harnesses under the dash, if the bulb dims or goes out, you have narrowed down the location of your short. Pay extra attention to harnesses & wires that are routed past metal objects. Keep in mind that moving a harness will move other harnesses & wires so be careful not to drive yourself crazy thinking you have located the problem when it is the harness next to it. Once you have located & corrected the short check it again to make sure you do not have any others.
Other locations that may cause shorts for the parking lights are behind the kick panels & rocker panels.
Post back to let us know what you did & how it went. If you still can't find the short I may have some other suggestions.
