Yeah the rollers are an easy fix. Been a while since I did it, but I think the steps below are how it's done.
Remove window handle, arm rest, then door panel.
Pull off the plastic water shield.
Remove the two bolts holding in the window stop and the pull the window stop out.
Roll the window down slowly. Before it gets to the bottom, reach in to support the window. continue rolling it down until the roller comes out if its guide.
Pull the clip out of the roller then pull the roller off its shaft.
The new roller should already have a clip on it. Just snap it on to the shaft.
Roll up the window slowly and guide the roller into its slot.
Roll up the window slightly then install and adjust the guide.
Then put everything else back together.
