Wiper problems only have high

Wiper problems only have high
My truck is only driven intermittently anymore. A while ago I was driving to work and noticed I only had high wipers and no washers. By the time I got to work, it worked as it should. Same on the way home, broken at the start, working correctly when I got home. That's the last time it worked properly, though.
Using a multimeter, I have 2 volts AC at 100Hz at the pump across the yellow wire, pin 4, and ground, pin 3.
Looking online, I found a place that said that's all controlled in the motor, so I bought a new wiper motor and put in, it still did the same thing.
Next was the SCCM, which I ordered and pulled my truck apart to find I had 4/5 connector locations populated with pins, but the new part only has 2/5 populated. Called the dealership I ordered it from to ship it back. I got that taken care of and she looked up the part needed with the VIN. It is an obsolete part, apparently, and there are none available anywhere she was able to look, assuming nationwide dealer network.
I grabbed a multifunction switch from the junkyard and gave that a go with the same results.
Does anyone know, is 2 volts AC and 100Hz the correct readings on that line, indicating I got a back wiper motor from the jump? Or is that the wrong signal and I will never have properly working wipers again?
I found a schematic that I've been using here on the site.
