Tonight my Grand Cherokee developed a strange problem. Using the key fob, the headlights turn on and stay on for the entire 30 seconds. No problems. When we start the car the headlights and the instrument cluster are dark. I can pull the control back and the highbeams turn on but low beams are out. I went through the fuses and all looks good. Not expecting anything I even hooked up the ODB2 reader,codes were clear. Any thoughts?
