I am one of the many victims of the defective Prius 2007 hatch opening switch. After 4 years the rubber cover turned to tar. I bought a new switch assembly and thought I’d change it myself.
These instruction at the PriusChat forum help enormously! The disassembly is not difficult if you know what to disassemble!
Double check for yourself, but the part number 84840-47020 is for the 2007 Prius without Smart Entry (the little rubber buttons to lock the door) and 84905-47010 with smart entry. They sold me the wrong switch, the one without smart entry. However, I understand the right one is about $40 more and I should be able to use part of the old assembly with the new assembly to make one that works and not pay the extra bucks.
I will do this!
