Fuse box,refer to your owners manual for location(s). go to index back of manual,see fuses,go to that page,has fuse box locations,fuse positions,fuse size with pictures....
Key word is *TEST* fuses! https://www.youtube.com/watch?v=NGgL0-NpiSA
Headlights need to be ON for testing. Use the video link above to see how it’s done. IF still not sure how to do the necessary testing - seek *hands-on* help from qualified personnel. IF no power to fuses - suspect failed headlight switch.
By *testing* the headlight system you may be able to determine what has failed - read back over the posted suggestions here. You need to watch the YouTube video!
where are they located
