I live in Langley, BC, but i am willing to drive a bit to find a good junk yard that i will find power window motors, relays and switches.
Washington seems to have a huge lack of 3rd gen J's in the yards... trust me, I've called most of 'em from Mount Vernon/Burlington northward on the I-5 Corridor.
You may be able to find one or 2 cars in Bellingham... I'll pull some names/numbers when I get home from work today. Now whether or not they have power windows, that's another story.
