Hi...
It's quite easy...
Juz go slow...
1. Chk for & remove screws holding the plastic panel to the door proper
2. Remove trisngular black pc covering inside of door mirror
3. Remove screw holding door release lever @panel
4. Carefully use fingers to separate plastic panel from door proper by pulling outwards. Points where there are plastic plugs can be kinda felt where panel feels stuck...pull outwards at thise points
5. Push door release lever & frame thru its hole so that it is freed from its location on panel
6. Now lift upwards whole panel to free it from its anchor points on door inner edge
7. Disconnect plug & cable from Power Window Switches module

With panel removed, take yr time to chk which part can rattle or makes sounds on vibration/movement.
Insulate those parts with pcs of sponge.

Dat's it! Done!
Freedom from irritating rattling sounds!
Yippee!!
