My suggestion is to get a repair manual if your going to work on your own vehicle, and it's easy and inexpensive to get a high quality repair manual. To be better prepared, read up on the job you're about to perform, it will show you how to remove the door panel and it may even have troubleshooting info for the window, but probably not. It will however have a wiring diagram, and that is very important when diagnosing electrical issues.
Try and you can have one in minutes, for less than $30.00.
