2002 S40 Rear power Window

[mxzxrider]

The rear power window in my daughters S40 has stopped working. Doesn't work with the drivers side switch or the actual rear door switch. I can hear a "click" coming from the door when I press either switch and the dome light dims while I'm pressing the switch, but no window movement. It's stuck 1/2 way down, so if anybody has any ideas, I (and my daughter!) would appreciate it!
