Happy New Year to you as well. I hope you had a good one.
If you are not getting power to the yellow or blue wire, I think the low/high wiper relay is bad or we have a connection issue. At least, that is what we need to check next.
If you look below, I highlighted the power wires for the motor to run. Both of these wires come through the relay.
The relay is under the hood. See pic below. Remove the relay and if there is another one having the same part number, switch them. If there isn't, inspect the connectors on the relay and where it mounts. Make sure they are clean, and tight, and there are no corrosion issues. If you want to physically test it, here is a link that explains how to do it:
Let me know what you find.
See pic below.
