Dorman - HELP Windshield Wiper Arm P/N:42579
Help keep your rear glass clear with the Dorman wiper arm 42743 from Dorman - HELP. This rear wiper arm holds the wiper blade against the rear window glass as it sweeps. It is a direct-fit replacement for the 2008-2017 Buick Enclave, designed to replicate the original rear arm's fit and operation on that vehicle.
A wiper arm uses spring tension to press the blade against the glass. Signs it may need replacing include a blade that streaks or chatters because it no longer presses firmly, an arm that is bent, or one that lifts away from the glass. If the arm is the cause, this part replaces it. See the "Vehicles it fits" section for full fitment details.

Which vehicle does this Dorman rear wiper arm fit?
It is a direct-fit replacement for the rear wiper arm on the 2008-2017 Buick Enclave. See the "Vehicles it fits" section for full fitment details.
What does a rear wiper arm do?
It connects the wiper blade to the rear wiper drive and uses spring tension to hold the blade against the glass as it sweeps.
What causes a rear wiper arm to fail?
Dorman names spring wear, snow damage and metal fatigue as reasons an original arm fails. Any of these can leave the blade unable to press firmly against the glass.
What are signs the wiper arm may need replacing?
Streaking, chattering, or a blade that lifts off the glass can come from a weak or bent arm. A worn blade can cause similar symptoms, so inspect both before replacing.
Is this wiper arm difficult to install?
It is designed as a direct replacement for the original arm. Follow the vehicle service information for the correct removal and installation steps.
