I ended up taking it to a shop that specializes in AC electrical issues and they diagnosed and fixed the problem.
The positive wire from the battery was not connected because it had disconnected from the back of the relay by the kick panel.
They soldered a bracket to hold it in place.
I have a 1991 LC 3FE. The dash was pulled to address some wiring issues for an after-market radio.
The windows were all working previously, but now none of the windows work. On the off-chance the switch was bad I replaced it with a new one from Switch Doctor, but still nothing.
Did I forget...
