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.
replaced both fuses still not working
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!

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....
