If you’re not getting switching voltage then it’s possible the light stalk itself is bad. For kicks, swap out the high beam relay (which you know works) with the low beam relay, they should be the same part and the high beams only pull about 10 watts of power more than the low beams.

Can a bad dimmer switch leave a car without high beams?

If you notice that the headlights remain stuck on either high or low beam then that may be a potential sign of a bad dimmer switch. A dimmer switch that is stuck on low will leave the vehicle without high beams, while one stuck on high will leave the vehicle without low beams and blind other drivers on the road if the vehicle is driven at night.
