Same thing happened the other week on my drivers side, no warning just came out to it in am went to open window and got no movement? just like you say you can hear a "click" from the motor. Took door panel off expecting the worse checked the wiring inside of gater that passes though from the a panel to the door, no sign of trouble there, checked wiring inside of the door shell, gave the switch a good blow with airline plugged back in again and the window worked straight away, sprayed some w/d down the window runners no problems since.Take it that neither driver side switch or passenger works? Did once sort out similar problem with relations Clio passenger window went down would not come back up (either switch) traced the problem to driver side wiring inside gater that passes from door to body shell (broken wire).
I'd try just removing the door card first checking the wiring and switches first.
Good luck all the best Houch
