The relay is on the door where the window isn't working. If you show me a pic of the bottom and any model number on the relay I can tell you where to test to confirm the relay is the problem vs a switch or electronics.

edit: your photo had the part # on it: tyco+ V23078-L1002-A303

It's a special relay that reverses polarity to the output terminals, shorting both to ground when not operational.

The small pins on the ends are the control pins; if you can plug it back in and test it, you should have voltage on the small pins when the switch is activated (up/down). one side for up one for down. If you get a '12v' reading across the small pins on both sides, the switches are fine and the relay is shot.

If you don't get voltage on the control pins then there is a switch or wiring problem. If you get voltage and the relay does click then it says the problem is down-stream; limit switch or wiring, but i think you said no click in the down position.
