If If both the low beams and high beams are not working then I would be looking at fuse #2 in the underhood fuse box. This is a 30 amp fuse.
If the fuse is ok then you will need to remove the headlight switch and do some voltage tests. I can assist you with that if needed. Here is a wiring diagram for you.
a friend told me that there is a lighting module under the fender that may be the culprit, the fuse you spoke of was replaced with a new one and still no lights
