A new windshield wiper blade, more tolerant to windshield friction variation, has been developed for 1988--90 C/K vehicles. Besides an improved wipe quality, the new blade includes a latch for attachment of the blade assembly to the wiper arm.
Use the new blade to correct blade chatter, streaks on the blade path or failure of the blade to make full contact with the windshield.

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.
