window will not go up

Sounds like the regulator is possibly bad. It's hard to say whether you can fix this without knowing your mechanical ability. If you don't have the right tools and knowledge, you can end up causing more problems and spending much more that you would have had you taken it to an experienced mechanic. If you want to do this, then get a good quality repair manual before starting on the job so you know what tools you'll need and how to perform the work.
