My one ton was running great. I was driving down the highway when the radio quit working. Didn't like the song, so did not think a lot about it. The issue I am having is that all of the lights except brake and turn also stopped working. I replaced the headlight switch, pigtail to switch. No luck. All fuses are good. Since my Durango gave up the ghost last night, I am down to the one ton to drive. Any thoughts??
