I can't be much help here, but a quick search in this forum for "window won't roll down" reveals several posts of similar issues. Reviewing them may give you a direction to go in for the repair. From what I've read here, your window switches are in series (one breaks, they both break) and since both switches are behaving the same, i.e., clicking noise at the door, I'd be willing to guess it is something mechanical with the window assembly in the door. Possibly the actuator cable/belt is broken, hung up or jumped the track. Might be easiest if you just go to your local mechanic and have him/her pop the door panel and visually inspect the mechanism and operation of the window motor and actuator.
