Condition

Some customers may comment on windshield wiper chatter/noise, or that the wipers are streaking.

Cause

Most wiper conditions are caused by either contamination or damage. Contamination by bugs, road grime, sap and/or a buildup of vehicle

wash/wax treatments may cause wiper streaking. Wipers can be damaged by any of the following:

- Extreme dusty conditions

- Sand and salt

- Heat and sun

- Improper removal of snow and ice

Correction

Note

Additional information on wiper performance, cleaning and maintenance can be found in Corporate Bulletin Number 06-08-43-003C.

Wash the windshield thoroughly and clean the outside of the windshield with glass cleaner. Also clean the rubber wiper blades using a lint free

cloth or paper towel soaked with windshield washer fluid or a mild detergent.

Tip

For a larger scale buildup on the windshield, use a non-abrasive cleaner such as Bon-Ami* (www.faultless.com) cleanser with a wet sponge, being

sure to use plenty of water to avoid scratching the glass. Flush the surface and body panels completely.

If cleaning does not improve the condition, replace the windshield wiper blades with GM P/N 22793882. The replacement blade is a dual extrusion

rubber material for durability performance.

Note

The outboard end of the passenger side wiper tends to sit off the surface of the windshield due to the design of the wiper blade, and the curvature of

the glass. This is a normal condition which leaves a "no contact" area at the lower edge of the wipe pattern, and no correction should be attempted.

The Full Size Utilities use a conventional blade design, which has a slightly different interface to the windshield than the flat blade design used on

the Pickups. Examples of the two designs and are shown in the graphics below:
