Help keep your rear glass clear with the Dorman HELP Rear Wiper Arm, part number 42853. It is a direct replacement designed to hold the rear wiper blade against the glass the way the original arm did.

A wiper arm links the wiper motor's pivot to the blade, and its spring presses the blade against the glass as it sweeps. Signs this part may need replacing include streaking, a blade that lifts from the rear glass, a bent arm, or an arm that slips on its pivot. If a weakened spring or damaged arm is the cause, this arm replaces the failed part.
