This bulletin is being revised to update new part information, add VIN breakpoints and 1995 model year. Also, a new air inlet grille has been released. Please discard Corporate Bulletin Number 43-82-06 (Section 8 - Chassis/Body Electrical).
CONDITION
Some of the vehicles listed above may exhibit wiper chatter (especially in cooler weather).
CORRECTION
Improvements to the windshield wiper system have resulted in new wiper arms being released for service use on vehicles after VIN breakpoints listed below:
Buick - SR419520
Cadillac - SR710430
Chevrolet - SR147606
Also, a new air inlet grille (P/N's 10279062-63) with revised wiper blade park ramp angles to lift the blades off the glass to prevent them taking a set, has been released for production after breakpoint and service. The screens are interchangeable for 1995 and prior model years, and should be used when addressing a chatter concern.
As always, evaluations of chatter should be made after the windshield and blades are properly cleaned.
Make sure that the correct wiper blades are in use for the vehicle in question.
Visual identification of the different blades from production are as follows:
1991-1994 = Rectangular holes in top of blade.
1995 = Prior to breakpoint, top of blade has no holes and can install to arm one way only.
1995 = After breakpoint, rectangular holes in top of blade.

The correct service part numbers and usages for the above listed 1991 through 1995 model wiper arms, wiper inserts, air inlet grilles, and blades are as follows:

Important:
