Greetings. Thanks for the video. This is one of many visual descriptions on youtube, and all of them show how to take apart the entire rear panel in order to get to the plastic switch parts. I did not do this. It was not much trouble to simply - cautiously - pop out all of the plastic part. Then I soaked and scrubbed them in WD-40. Then I dried them and reassembled all parts, including an $8 dollar rubber replacement part with the screws from ebay. It is not necessary to disassemble the rear door panels to clean off the melted rubber and reassemble.
thanks for sharing your experience, in my case it was not popping out, I was afraid not to crack the plastic panel, because it's very fragile so I decide to remove it entirely
I live in the rusty New England snow belt, and the button switch parts are completely corroded and I am unable to remove. I have two choices, replace (parts start at $80 on EBay) or just cut that part off and only keep the lift gate handle. Anyone know if I can get away with eliminating the button on a 2008 Prius?
