Looks like from what I have read I will need to pull fuse F5 and test out of circuit, and check connector J3 on the rectifier board.
I had this issue w/my Power Play. Wound up being the lower connector on the rectifier board. Do yourself a favor and re-pin those wires and get new housings. It was a PITA but fixed that and some other issues. For the backglass area GI it seems like it was the larger gauge wire on the lower connector . Red wire I think.............
Look at the middle of the big bottom connector on the rectifier board (the one with all the fuses). One or probably two of the middle pins will likely be brown. As pinkid said, you will need to repin those connectors but you should do all of them at once. They all need to be replaced if they are the originals.
