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

You'll have to test the wiring to be sure but it's likely a bad dimmer switch.

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.
