i have a 99 silverado and all of a sudden, my headlights stopped working. i checked the fuses and replaced the relay. the relay was fine but the lights still do not work. please help, any suggestions would be greatly appreciated. this truck is a work truck so i cant afford to take it to the dealer. thank you very much,

check the light bulb

 

replace the dimmer switch

 

This may be the day night sensor on the dash.
