I have a 1998 Chrysler Concorde with the following problem. The headlights will not work by the switch. They come on when I start the car but the switch is in the off position. I can't turn them off or on with the switch. I replaced the headlight switch but still have the same problem. Any suggestions for repair would be greatly appreciated. It's been a great car but I'm not ready to give up on it yet. It currently has 222,000 miles on it.
