2011 Toyota Corolla - Body ECU?

#1
My drivers side window switches have quit working. The locks continue to work and the other windows can be operated from their respective doors. I had the local Toyota dealership take a look at it and they said that the BODY ECU needed to be replaced (at a total cost of around $1100). As you can imagine, I don't want to spend $1100 on one window not being operational. Could someone tell me exactly where to find the body ecu and what it looks like? (a photo of it would be incredibly helpful).
