Which relay is the one for the power windows on my 2002 Taurus. I know all the fuses are good but no power to them since the passenger mirror was knocked off.

That sounds more like a wiring problem in the door. Remove the inside door panel and check for pulled, broken or loose wiring running to the window switch panel. Bet you'll find it there. Relays are in the power distribution box under the hood. The layout diagram is on the bottom of the cover panel. Good Luck!
