Standard Ignition Windshield Wiper Switch P/N:WP647
Standard Motor Products
Standard Ignition WP639 windshield wiper switch for the 2017-2018 Toyota RAV4 and other vehicles controls the wiper and washer functions. If the switch is the failed part, this one brings back control of the windshield wiper functions.
Wiper speeds that skip, delay settings that do nothing or a washer that will not spray can mean the switch is worn, though the wiper motor or a blown fuse can be behind the same signs, so find the cause before replacing it. This listing is one switch, and the car needs one.
It fits the 2017-2018 Toyota RAV4, the 2014 and 2017-2018 Toyota Highlander and the 2018 Toyota C-HR.
