So the brake lights and turn signals work in the front and back. But when you turn on headlights the whole back stays dark, and no dash backlighting comes on. When you switch to parking lights nothing happens. I have checked fuses and they are all good, I went ahead and replaced them just for the sake of it. The dimmer switch is turned all the way up and does turn on dome lights. I should also note there is a trailer plug wired in also. Where should I start?
