You should not have power when the switch is off. If you have power on those fuses than the lights should work. The last thing to check is the bulbs check them and see if they are good.

my dash lights suppose to be on once i turn on my switch but there not either so would you say that thats a bad fuses that wouldn't have anything to do with my bulbs right

Answer

If the dash lights are out also I would lean more toward a switch. The switch runs all the lights.The fuses run individual lighhts
