Dorman - HELP Windshield Wiper Arm P/N:42021
Keep your rear view clear with the Dorman wiper arm 42859, a rear wiper arm built as a direct-fit replacement for the 2009-2012 Toyota RAV4, 2010-2013 Toyota Highlander and 2009-2013 Toyota Matrix. It holds the wiper blade against the rear window glass and carries it through every sweep, so a weak or bent arm is worth replacing before it affects your visibility.
A wiper arm relies on spring tension to press the blade evenly against the glass. When that tension fades or the arm gets bent, the blade can lift, chatter or leave streaks across the rear window. If a worn original arm is the cause, this Dorman replacement is designed to take its place. See the "Vehicles it fits" section for complete fitment details.
