Explaining High Beam Circuit?

Cycle the dimmer switch with your foot about 20 times. You won't because nobody does, but the contacts get dirty and the switch stops working.

When my headlights would act up I would spray WD-40 on the top of the dimmer switch button then cycle the mess out of it. The WD would seep past the peened over rivet that holds the button to the switch, eventually cleaning the internals enough to where it worked fine again.
The easiest way to tell if you're having contact, or spade connector issues is by looking at the molded plastic connector cover for obvious hot spots. If that's the case, replace both the dimmer switch and the connector with new parts.
