Maybe not what you want to hear, but it's usually very difficult to diagnose electrical problems without the vehicle in front of you. The wiring diagrams are here: https://oljeep.com/gw/elec/GW_wiring.html Use your multimeter and trace out the problem. If you need to, print or photocopy the diagrams and follow the circuits with colored pencils.

ACC is usually an abbreviation for accessory.

The TSM will have a section that describes the wiper motor and its wiring. This is where I would start for the wiper motor.
