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.
