Wiper switch

[ShinyC10]

After rewiring the truck, I ended up with only one issue. The wipers only work in “low”. Test I don’t care if the intermittent works, as long as low and high works. When “low” is on, I show 12-14v depending on the truck being on. When I try to turn them on “high”, they stop moving all together. Multimeter shows 12-14v still on the “low” side and 2-5v on the “high” side. Also, I’m showing 12-14v inside the cab at the fuse and 2-5v in the engine bay at the firewall so I assume the issue is in the switch? Pump for the washer fluid works too. Everything was pretty much plug n play with the AAW harness and I didn’t remove the column from the truck.
