WIPER ARM HINGES CORRODED

DESCRIPTION

On some vehicles, rust may appear on the wiper arm hinge. This is caused by the paint film on the retainer coating being too thin and galvanic corrosion appearing on the wiper arm hinge. The paint on the retainer coating has now been increased and the configuration of the arm hinge has been changed from a single bush to a double bush. To prevent galvanic corrosion, the contact between the arm head and retainer has been removed. Customers having this concern should have their vehicle repaired using the following repair procedure.

REPAIR PROCEDURE

1. Verify customer concern.

2. Replace the front wiper arms with modified ones. Refer to MS3 online instructions or Workshop Manual section 09-19 WINDSHIELD WIPER ARM REMOVAL/INSTALLATION.

NOTE:
Reuse the old blades.

3. Verify repair.
