Hi Regie,Yep done all you mentioned and even my auto electrician couldn't resolve the problem. Thats why I have asked the original poster how they fixed their issues.
I saw your post re: strange problem with your Nissan. I wonder if your problem has been fixed. I would like to know the solution. Because I have similar situation happening to my 2011 Nissan Pathfinder. I removed and replaced all of the fuses in the car, car work for few days then the problem starts again. Like the actual signal light is on but nil on the dashboard, vdc light is suddenly on, headlight also is always on by itself, etc.
