I use a butter knife for this operation. Pry off the plastic cover around the door handle. This will give you access and you should be able to remove the door lock/window buttons/window lock assembly and pop off the three connectors.
Someone on here has a thread with pictures. If I find it I will add a link.
Edit: Found the link: Thanks to
borland for a great write up. The first 2 pics will be what you are looking for.
