Got in my 2005 van this morning and the headlights will not turn on. I checked all the fuses and they are good. I'm assuming it is a ground somewhere but I'm not sure where to start looking for the ground location. Maybe its the same location as my radio ground too since the light on the radio seams to be fading in and out too. 305,000 miles and I'd like to keep it going. Any help on ground locations would be appreciated.
