Got the wipers to work by turning the wiper knob on and off rapidly several dozen times. Low beams don’t toggle on when I flip the lever, just have high beams all the time and the little blue indicator stays on. I think I narrowed that to an internal problem in the switch though.

I’ll look at my relay. The intermittent wipers actually work very well.
