Dorman - HELP Windshield Wiper Arm P/N:42580
Help keep the blade pressed evenly against the glass with the Dorman - HELP Windshield Wiper Arm, part number 42533. This front left arm carries the wiper blade across the windshield as the wiper motor drives it. It fits many vehicles, among them the 1995-2005 Chevrolet Blazer, 1994-2004 Chevrolet S10 and 1994-2004 GMC Sonoma, as a direct-fit replacement for the listed applications.
A Dorman wiper arm is a practical swap when the original no longer holds the blade firmly. Signs the arm may need replacing include streaking or chattering from weak spring tension, a blade that lifts off the glass at speed, or an arm that is bent or loose on its pivot. See the "Vehicles it fits" section for the full list of fitting vehicles.
