most likely the motor went out...
does it budge at all when you try to raise it??
Try this to get it to go up : Let it sit for a while (sometimes if you let it cool it may work for a brief moment)
Then start the car.... start it - do not just turn the key to the on position. push/ pull up the button to make the window go up and hold it. see if it goes up at all.
if nothing ---- sorry
if it goes up a bit and then stops.... then motor is bad definitely.... Repeat above steps .... let it cool down completely , start car, press "up" button.
good luck ----- and definately time for this
