Attached is a PDF [28 pages] one may download to see the steps, time, hints, and tools. Hopefully the numerous pics will help.
I am NO DIYer in terms of a qualified mechanic. SO, don't feel you cannot do this on your own. My part, used, was about $225. I highly suggest you have it inspected before messing with install. Honestly, mine works, but the guys who removed it made a slight twist to the pantograph and I feel, I might be re-visiting this replacement soon.
Therefore, although the newer, upgraded OEM part is MUCH better in terms of adjusting the 'window gap' issue, my older one actually has a better pentograph. I 'might' be tempted to try the fix of that pivot point and replace it to the newer mechanism and get the final part I want/need.
Do take your time adjusting the window alignment before replacing the interior door panel as I HATE doing two screws with all my heart: Door handle to armrest [gawd I hate those two screws and it never gets easier
Now, feel free to comment away and/or ask questions.
