I need to replace the driver's electric window switch assembly. The dealer wants over $500 for a new one. Where I used to live, I'd head out to the U Pull It junk yard and get one. But now I don't live by any of those. Is there some sort of online reputable source with a good selection of Prius Gen 3 parts?
While I can't say for sure this is what you need, you may be able to just go get an aftermarket from RockAuto: 2015 TOYOTA PRIUS 1.8L L4 ELECTRIC/GAS Power Window Switch | RockAuto Otherwise some Pick Your Part type places have online resources where you can request and try to get a part from them, if it's available.
Even years ago when I would still go to the local U Pull, they were already networked among themselves, and somebody could say "no, we haven't got one of those, but that place across town has three." Now it's commonplace to find such searchable sites online. LKQ is one example.
There's endless options online... Just start searching... I prefer Ebay because they provide a no fault refund for items under $300 if you and the seller have a dispute that can't be resolved. Also just threatening to give a seller a negative ratings evokes lots of generosity because most sellers do all they can to keep their approval rating above 98% because they have lots of competitors selling the same thing as they sell.
