# WINDSHIELD WIPER OPERATION NOISE/ARM MAY STRIKE MOLDING

#### MODELS AFFECTED: 1988 RIVIERAS

Some 1988 Rivieras may experience a condition of a ticking noise during operation of the windshield wipers. This may be caused by the windshield wiper arm striking the lower windshield reveal molding (see Figure 1). To repair this condition, use the following procedure:

1. Raise the hood.

2. Remove the wiper arm assembly.

3. Remove the wiper blade from the wiper arm.

4. Remove the hose clips under the wiper arm to allow the wiper arm to rest on a flat surface as shown in Figure 2.

5. Bend the wiper arm at the point shown in Figure 2, and check for clearance from the reveal molding.

6. Measure the height from the surface to the washer nozzle, Figure 2. The measured distance should be less than 25mm (1.0 inch).

7. Reinstall the hose clips on the wiper arm.

8. Reinstall the wiper blade on the wiper arm.

9. Reinstall the wiper arm assembly.

10. Lower the hood.

11. Operate the wiper system at high speed, activate the windshield washer and check for proper clearance.
