RX7 FD Windows Won't Roll Down

[ZGN]

I have a 1992 RHD FD that the windows won't roll down on either side.
They just both stopped working at the same time.

Fuse is good, no power to the main window switch.
I have traced down the power in from the switch, blue-white wire through the fender connector into the flasher box, 34-3181701-2, and tested voltage on the flasher box power window connector and I get zero voltage with the car turned on. I replaced with with another flasher box with the same results. Must be further up the harness. Any ideas while I troubleshoot more?

Who would have though the FD RX-7 window switch gets it's power from the flasher box.
