Does the rear window go up with the exterior key switch or just down. I ask because mine only goes down, The key will turn in the oposite direction, but it does not do anything, no clicks, nothing. So did a little trouble shooting yestarday. The FSM says to test cont at the switch connector at pins 1 and 2(up). There is not wire in pin 2 in either side of the connector. It is capped off on both sides.

 

Sounds like your key switch is shot. Mine used to go up and down, then it would only go down. Now it doesn't do either, so I have to use the switch inside.
