1984 - 1996 Corvette: Service Bulletin: Chattering Wiper Blades or Wipeability

Subject: CHATTERING WIPER BLADES OR WIPEABILITY
Model and Year:ALL PASSENGER CARS AND TRUCKS
Source: Chevrolet Service Bulletin
Bulletin Number: 91-126-8E - (12/31/1990)

TO: ALL CHEVROLET DEALERS

Condition:

Chattering and poor wipeability comments may be due to the windshield glass and/or wiper blades becoming contaminated by insect residue, dirt, road grime, carwax etc.

Correction:

1. Clean the windshield glass with GM #1 050011 (Bon Ami) glass cleaner or equivalent.

IMPORTANT: The glass is clean when rinse water does not "bead-up," but "sheets" across the entire glass surface. Multiple cleanings may be required to remove all contaminants.

2. Clean the wiper blades by using a cloth that has been saturated with full strength washer solution and wipe vigorously. Rinse the blades with water after cleaning.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
