Bulletin 84-8-10Date April '84
Ref. No.. 84-195-8
SUBJECT: CHATTERING WINDSHIELD WIPER BLADES AND/OR UNEVEN WIPE
MODELS AFFECTED: ALL MODELS
Windshield glass and wiper blade elements may become contaminated by wax left on the glass, after a car wash, or chemical compounds from the atmosphere and can result in chattering wiper blades and/or uneven wipe.
To correct this condition, clean both windshield glass and rubber blade elements as follows:
1. Clean windshield glass with a glass cleaner that will not harm the paint finish or scratch the windshield. One such product that can be used is the Bon Ami (R) "cleaning powder". The glass is clean when the rinse water no longer "beads-up" but "sheets" across the entire glass surface.
2. Clean wiper blade elements using a cloth or towel that has been saturated with a solution of 50% water and 50% GM Opti Kleen or a solution of 50% water and 50% methanol alcohol. Rinse the wiper blade with water and reinstall on the wiper arm.
