Hi,

Chances are the fuses are bad. There is one for each light. I attached a picture of the fuses. First locate them and check the fuses and make sure there is power to them. If power is present and the fuses are good, I suspect it is related to the switch itself.

Let me know.

Do you have daytime running lights? Do they operate? If neither the head lamps or fog lamps work, we would have to assume this is related. Each headlamp and the fog lamps have a fuse so it is unlikely all three fuses failed at the same time. However, we need to check them just to make sure they are okay. Then we need to go to the switch and turn the head lamps and fog lamps on and measure voltage coming out of the switch. If nothing then the switch is most likely failed.

Take a look at these diagrams and let me know what you find with the fuses and then power coming from the switch. Thanks
