Dorman - HELP Windshield Wiper Arm P/N:42021
Help keep your view out the back clear with the Dorman HELP rear windshield wiper arm, part number 42024. It is a direct-fit replacement for the 2012-2020 Chevrolet Sonic and is designed to match the original arm's fit and function, with an emphasis on durability and dependable performance.
The wiper arm holds the blade against the rear window glass and carries it through each sweep as the wiper motor turns. Over time, an arm can lose spring tension, be damaged by snow, or crack from metal fatigue. When that happens, the blade may lift away from the glass and stop clearing it properly.
Signs the arm may need replacing include a blade that no longer presses firmly against the glass, streaks or missed areas, or an arm that is visibly bent or cracked. If a worn or damaged arm is the cause, this unit replaces it.
