Dorman - HELP Windshield Wiper Arm P/N:42021
Built to hold the wiper blade against the glass and sweep it across the windshield, the Dorman - HELP Windshield Wiper Arm 42827 is a front left replacement for a worn or damaged original arm.

Signs a wiper arm may need replacing include streaking or chattering because the blade no longer presses evenly on the glass, an arm that is bent, or an arm that feels loose.
