Replacing Broken Auto Window Switch/Button

I have a 1999 Jeep GC in need of a new rear passenger auto window button (one on handle is broken). I have the new one but do not know how to access. Any help would be appreciated. Mike.

I believe you have to remove the door panel and once it's off it is an easy fix to replace the unit.

The tricky part is the plastic parts that secure the panel to the door itself; I hear they break frequently and are expensive.
