2001 Dodge Dakota V8 Four Wheel Drive Automatic 135000 miles
My parking lights stay on(very dim) after turning the car off and there is a quiet buzzing sound. At the same time I can't turn the headlights on. Also the 4 Wheel drive does not work and automatic door lock. It all quit working at the same time. I've tried switching the light relay but it hasn't helped. What else can I look at?
