I believe it is under the drivers lower dash area, somewhere close to the fuse block or the middle dash area under the ash tray area.

Pretty sure that relay is just for the locks. The windows use a circuit breaker plugged into fuse panel

Only the locks use a relay, the windows use a circuit breaker as Blazer74 stated. However, adding a relay harness to the window wiring harness makes them work much better.
