Have you checked fuses 15 and f25, is there corrosion? If they are good what you can try is disconnect your batter cables. Remove fuses f15 and 25, touch the cables together for about 30min, hook up the cables and then insert the fuses.
F25 I believe controls the relay for the foglights, you also might be able to check to see if there is any power on that circuit.
