Standard Ignition Windshield Wiper Switch P/N:WP619
Standard Motor Products
Standard Ignition WP633 windshield wiper switch for the 2011-2012 Lexus RX450h and other vehicles controls the wiper and washer functions. The driver uses it to set wiper speed and delay and to spray washer fluid.
Wipers that ignore a speed or delay setting, or a washer that will not spray, can mean the switch is worn. These signs alone do not prove the switch is at fault, since a blown fuse can cause them too.
This switch fits the 2011-2012 Lexus RX450h and the 2009-2011 Lexus RX350, and each of them takes one.
