Fuse box diagram is missing

So, I just got back from the auto parts store with my Haynes manual and aaarrrrghh! there is no fuse diagram in it. The panel of my fuse box is missing the diagram and my heater fan keeps coming on and off, my radio fuse keeps popping, and I want to know if it's a fuse problem. Does anyone know where I can find the diagram online? Many thanks!
