Window won't roll back up

Hey, so I have a 95 ford bronco 302, 5.0L V8, my passenger window will not roll up sometimes it works sometimes it doesnt what is wrong? My passenger window worked just fine when I bought the bronco over the summer but about a 2 months ago it decided not to work very well at all. My friends will accidentally roll it down and when I get home late at night I shut my bronco off and turn the key to the on position and it will sometimes roll up but about a week ago my cousin rolled it down because she didnt know not to and it rained last night and I have had enough of it I need it up and to be fixed. What is wrong? I know its not fuses, it rolls down but earlier when I tried rolling it up it didnt make any noise like it was trying at all and I dont think it has ever made a noise I need help! I live on a farm in iowa and its beginning of winter please help me ASAP we get horrible amounts of snow blown into my driveway.
