GM 22094228 Arm Assembly, Wet Windshield Wiper *Black

If the windshield wipers do not operate, check the fuse and replace it if necessary, then verify the switch operation and repair or replace it as needed. Inspect for corroded, loose, disconnected, or broken wires and clean or repair them as required, and examine the ground circuit for the wiper switch or motor, making repairs as necessary. If the wiper motor makes a humming noise, gets hot, or blows fuses, it may be damaged internally and should be replaced, while any bent, damaged, or seized wiper linkage should be repaired or replaced. If the wiper motor operates but one or both wipers fail to move, check for loose or disconnected linkage and repair or replace it as needed, and ensure the wiper arms are secure on the pivots, replacing both the wiper arm and pivot assembly if necessary. If the windshield wipers will not park, verify the wiper switch operation to ensure it properly interrupts power to the wiper motor; if the switch is functioning correctly, the wiper motor parking circuit may have failed, necessitating a replacement of the wiper motor assembly. Before installing the arms and blades, operate the wiper motor at least once to ensure correct positioning, and then recheck using the highest wiper speed on a wet windshield to confirm that the arms and blades do not contact the windshield trim.
