Dorman - HELP Windshield Wiper Arm P/N:42021
When a bent or weakened rear wiper arm leaves the blade skipping across the glass, the Dorman HELP Rear Wiper Arm, part number 42513, is a direct-fit replacement for the 2010-2017 Chevrolet Equinox and 2010-2017 GMC Terrain. Dorman designed it to install and operate like the original rear arm on these vehicles and built it for durable, dependable performance.
The rear wiper arm holds the blade and uses spring tension to press it against the rear window glass as the wiper motor sweeps it back and forth. Signs this part may need replacing include a blade that lifts, skips or streaks from weak spring tension, or an arm that is bent, cracked or broken. See the "Vehicles it fits" section for complete fitment details.
