Hi I am new to honda-tech but I have a major problem. Well at least to me. I was hoping you guys can help me out. I have a 98 civic hatch and when my headlights are not on and I use the left turn signal it blinks but so does my interior lights and radio. But when I turn on my headlights evrything stays on including my turn signal it just stays on and doesnt blink. Everything is all messed up so it would be great if you guys can tell me what I can do thanks.
