My only thought is the cable deal (think they call it the regulator) has gone into a bind or wound loose and now it wont go up, but you should be able to hear the motor with the car off just sitting there, no need to remove door panel to listen.
Yep she clicks.. .. what a day .. busted every clip holding tyhe door panel on.. cut the membrane on the door and while pushing up on the window andpulling on the glass ..still nothing and the window does not budge a millameter..I'm so pissed right now.
As long as you didnt hear a CLUNK or have the window try to roll up crooked, you might be ok (from having the motor or components being replaced). Me thinks it's electrical and not mechanical. Check what you can like fuses and such but you're probably gonna have to pull the panel and investigate.
