My DA came with a shitty ebay HID kit called Xentec, I quickly removed it because it is crap. My friend and I rewired it back to stock, tested it out, and everything worked, hi-beams, low beams etc. Now my fogs dont work, sometimes the button lights up for them and only one works, or sometimes the button doesn't light up at all and both don't work. I just checked this morning and now only one of my headlights work and my fogs dont work at all, the button doesn't even light up. How does it go from working one day to not the other when nothing has been changed? I keep having these electrical problems...

 

Did you check the fuses? Maybe theres a loose power wire somewhere thats not tapped up or connected and its touching metal.

 

It could be some messed up wiring somewhere, the guy that owned it before me half assed everything, I'll have to check around. I have checked all the fuses and they are all good. Would some of them being higher amperage than what they should be have anything to do with it? For an example, I believe my headlights are 15's right now and normally I believe they would be 10's.

 

You may want to put the right fuse in the slot but its not going to cause the problems your having. Check over all the wiring, the only thing I can think of is an exposed power wire grounding out somewhere.

 

Make sure the grounds by the headlights are attached to the chassis. Also if I remember the switches sometimes go bad too. Are you running usdm headlights or jdm?

 

I have usdm headlights but turns out its nothing to with the wiring in the car itself, the plug I bought for the bulb was in the packaging too long it seems like and the wire only sends the signal to the bulb when you bend it, so I will be returning it. So the headlights work, now just my fogs still don't work at all.
