Well I just discovered that my brake lights are not working, I found the fuse and it was blown and I replaced it with a few and they just blew as soon I put it in place, I know there is a short but I just don't even know where to begin to start looking too see where is it. I am assuming it was from last night cause they were fine up til last night when I ran it through a car wash and I assume water got in some where but I don't know where.

Where do I even start?

 

well it could be a a lot of things, but i would start with the relays under the dash right by your fuse box, or under the hood depending on the model and year, if the relay went it could be grounding out as soon as you touch the brake pedal poping the fuse, there is also the actual brake sensor on the back of the pedal assembly, but i rarely have seen those go, i'm guessing its the relay or a ground issue, do you have a test light,lol its sometimes easier just to take it to a garage if you have one you trust, wiring issues are a bi$ch. and they can get costly, but if you have access to a few extra relays from a friends car you can try switching them out to see if it helps the prob.n hope this might give you a few ideas,good luck.

 

pull out the bulbs in the tails and see if there's water in the prongs. Also check the connectors on the lights.

 

i would pull all bulbs out and visual inspect each one. after the inspection if you can't find what's wrong begin putting bulbs back in one at a time and see which one blows the fuse. if that doesn't happen you have a problem elsewhere, but is always best to start with the easy stuff. Keep It Simple Stupid.......KISS

 

that would happen to me when i put my 98+ tails....turns out the taillights had a cut wire basically a short..idk
