so from what I understand everything under the fuse "acc" is my dome light, head unit, power locks, cigarette lighter ,and headlights. my car has always been a little scary wiring wise but haven't had a real problem until recently. sometimes none of the accessories would work at all then if I hit a bump the right way they would turn back on. I also had a problem with my head unit constantly restarting and this would happen for a about a day then stop every once in a while. lastly my dome light has always flashed sometimes random and usually when I hit a bump. now my all listed above completely stopped working. that makes me unable to drive my car at night because of my headlights because it is my daily driver. I am guessing it is a loose connection somewhere so if anyone has any ideas where I should look or any input at all please reply. thanks

 

The headlights aren't part of the ACC fuse, unless you mean the interior lights. Do you have an aftermarket head unit ? Sounds like someone spliced into the ACC circuit and there's a loose connection.

 

well my headlights aren't working right now. and I baught the car and the guy had an aftermarket headunit prior to selling it so he could have gotten his 12v from there I just used the wire sitting there. the guy did some sketchy stuff with his wiring. the last time I turned the car on the acc were on then I tried to turn on the headlights and the acc turned off and the headlights didn't do anything
