I was driving down the highway when the radio quit working. I didn't think much of it because I didn't like the song anyway. It turns out my headlamps, dash lights, running lights, and clearance lights all quit at that time. Brakes and turn work. No bad fuses. Power locks and windows work. Replaced switch to no avail. Pigtail looks good too. Thoughts?????? My Durango died, so I am down to this one for now.
