Dorman - HELP Windshield Wiper Arm P/N:42879
Help keep the rear glass clear with the DORMAN HELP windshield wiper arm, part number 43531, a rear arm that holds the wiper blade against the back window and carries it through every sweep. It fits many vehicles, among them the 2011-2015 Toyota Prius, 2012-2015 Toyota Prius c and 2012-2015 Toyota Prius Plug-In. See the "Vehicles it fits" section for the full list.
A rear wiper arm uses spring tension to press the blade onto the glass while the wiper motor swings it back and forth. A weak spring, a bent arm or snow damage can leave the blade lifting, skipping or streaking. If a worn original arm is the cause, the 43531 replaces it and is designed to hold the blade against the rear window again.
