The head lights are working, but not the high beams. on 2004 Toyota Highlander

High beams not working, but head lights are. Could this be a fuse, do high beams have their own bulb, or is it something else?

Could be several things. Without a wiring diagram, you can check the fuses and bulbs, but not much else. Start by checking power to the bulbs and work your way back to the switch.
