Welcome to 2CarPros.

Have you checked to see if there is power to the wiper motor? Also, I just read through the schematics for the wipers and the signals and I did find one common ground. The first three pics below are related specifically to the wiper motor. Pic 4 is from the exterior lighting schematic. In pic 4, I circled a common ground. It indicates the location. Check to make sure that has a good connection without corrosion and nothing is loose or broken.

Let me know what you find.
