Help keep your view through the windshield clear with the Dorman - HELP Windshield Wiper Arm, part number 42547, a front left arm designed to hold the wiper blade against the glass the way the original arm does. It fits many vehicles, among them the 2003-2006 Chevrolet Silverado 1500, 2003-2006 Chevrolet Silverado 2500 and 2003-2006 GMC Sierra 1500. See the Buyer's Guide tab for the full list.
A wiper arm uses spring tension to press the blade against the windshield as it sweeps. Signs it may need replacing include a blade that lifts off the glass or chatters, streaking from weak pressure, or an arm that is bent or loose. If the original arm is the cause, this Dorman wiper arm is designed to replace it, so diagnose the problem before ordering.
