^ No real need to pay for a paper manual, *almost* anything you'd need is linked in my sig, and easier still to read on a large monitor or TV where you can zoom in, along with being able to put them on your phone to always have with you or at least at the vehicle while troubleshooting... along with Forscan on the phone and a OBDII dongle, I gotta love phones as portable computers.
Besides, the applicable window wiring diagram was already posted in post #2.
Jumping the battery to the switch panel blue/black is an option but not really needed. You can just follow the wiring diagram and test for 12V at each point in the circuit including on the relay box contacts. Wherever there is not 12V when there should be, move one point on the wiring diagram closer to the battery to check again. A multimeter alone can solve this.
