Welcome to JustAnswer, my name is XXXXX XXXXX I'm here to help get your problem resolved. This is a common problem caused by the headlamp drive module which looks like a relay in fusebox under hood. It is #46 in picture, swap it with #45 to see if they come on. If so replace, its about a $7 part at parts store. here is a diagram of fusebox. Let me know if you have any questions, thanks.
