need the location of the fuse box and or fuse for the emergency flasher button

I have attached wiring diagrams for both the exterior hazard lights and the interior switch illumination. If you look at the fuses you will find a description of the location of the fuses. One possibility though is that your multifuntion switch is failing as the circuit runs through it and can cause the hazard circuit to fail while other functions such as turn signals still work. If you don't find a blown fuse that is most likely the problem.
