Passenger side window just stopped working and I have no idea why

What is your question?

I drive a BMW 318i coupe two door and my passenger side window was playing up a little and today I put it down a little bit but now it just wont go back up or go down. When I press the up button it makes a small click sound but no motor noise and I also noticed that the lights dim in the car when I try and put it up, but it just wont budge! I would really appreciate if someone could help me figure out this problem! Thank you.
