I have a 2004 Chevy Impala the headlights shut off coming home from work 2 nights ago fortunately I was only a block from home. I tried to manualy turn them on with no luck . Checked the fuses they were fine. In the morning upon starting the car they came on as normal but when out shortly after however I was able to turn them on manualy . When leaving work I encountered the same problem they would not go on at all . After calling home I tried one more time and they came on as normal again.very frustraing. Any and all help with this problem would be greatly appreciated ,thanks
