I have the low beam lights working. The high beams are not working at all. When I pull back on the switch to flash the brights no lights and the indicator light does not come on either. I have put power to the high beam wire and the lights come on, so I know the lamps are good. Have checked all the fuses as well

This sounds like the headlight switch is bad, but we should check the fuses. If the fuses are okay, I would test through the multifunction switch and the headlight switch as well. This guide can help you test the fuses and check for power, and I have included the headlight wiring diagrams so you can see which fuses to test and how the system works.
