BULLETIN

The following procedures are recommended to maintain windshield wiper blade
performance.
All models.
OP CODEDESCRIPTIONTIMEOPNT1T2
N/ANot Applicable to Warranty±±±±
Recommendations for Windshield Wiper Maintenance, Cleaning and Use:
1. Scheduled Maintenance
Check wiper rubber blades every 4 ± 6 months or 7,500 miles for wear, cracking
and contamination.
Clean glass and rubber wiper blades if blades are not clearing glass adequately.
If this does not correct the problem, then replace the rubber elements.
2. Cleaning Procedure
Wiper Rubber: Bugs, dirt, sap and road grime on blades will cause streaking.
Clean wiper rubber of road and environmental debris using cloth or paper towel
soaked with windshield washer fluid or mild detergent.
DO NOT USE fuel, kerosene, or petroleum based products to clean rubber wiper
blades.
Windshield: Bugs, road grime, sap and car wash wax treatments decrease wiper
performance.
Rinse windshield with water and apply non±abrasive cleaner, such as Bon±Ami
(www.faultless.com), with a sponge.
NOTE:
Make sure to use plenty of water with all powder based cleaners so the glass is
not scratched.

3. Contributors to Poor Performance/Decreased Rubber Blade Life (require rubber
replacement)
Dusty areas cause the rubber edge to wear quickly.
Sand and salt used for road conditioning during winter causes the edge to wear
quickly, so areas with significant snowfall require more frequent wiper
replacement.
Heat and time cause the rubber to become excessively ªpermanent set,º so the
rubber does not turn over, resulting in streaking and/or unwiped areas on the
glass.
Rubber is easily cut or torn while using ice scrapers on the glass.
Rubber can be torn when pulling blades off a frozen windshield.
Using wipers instead of an ice scraper to remove frost and ice from the windshield
during a car warm up can dull, nick, or tear the rubber.
Banging wiper on the glass to remove ice & snow can cause the blade to bend
and rubber to come out of the blade providing the potential to scratch the glass.
Ice forms in wiper blade pin joints, which causes streaking and unwiped areas. To
remove ice from pin joints, compress the blade and rubber with your hand to
loosen the frozen joints. To prevent this condition, use winter blades with a rubber
cover.Maintenance,

B HOW TO USE THIS MANUAL
The ground points circuit diagram shows the connections from all major parts to the respective ground points. When
troubleshooting a faulty ground point, checking the system circuits which use a common ground may help you identify
the problem ground quickly. The relationship between ground points (
EA, IB and IC shown below) can also be
checked this way.

RELAY
Basically, an electrically operated
switch which may be normally
closed (1) or open (2).
