HIGH Speed Position
WARNING: This page is about a different car, the 2003 Lexus RX 300 and 2002 Lexus RX 300. However, it is still accessible from the selected car via links, so may be relevant.
With the wiper switch turned to HIGH position, the current flows through TERMINAL 17 of the front wiper and washer switch to TERMINAL 8 to TERMINAL 4 of the front wiper motor to TERMINAL 5 to GROUND and causes the wiper motor to run at high speed. See WIRING DIAGRAMS .
