This bulletin supersedes the August 1988 Service Guild article on the same subject.

Some customer comments have been received on early production 1988 Cutlass Supreme models concerning performance of the windshield washer system. The following changes can be made to enhance the washer system performance.

Step 1 (On vehicles with VIN JD309364 or lower)

1. New wiper arms with a larger diameter washer solution delivery hose can be installed on these vehicles to increase the volume of washer fluid.

Wiper arms - 20469530 (Right Hand) - 10091282 (Left Hand)

Step 2 (On vehicles with VIN JD328342 or lower)

2. The washer pump wiring connector indexing can be revised, as shown in Figure 1, to increase the rate of washer fluid applied to the windshield.

The procedure which must be followed for removing the Metri-pack 150 series terminals used on this connection is shown at the beginning of Section 8A in the 1988 Service Manual.

Step 3 (On vehicles with VIN JD352275 or lower)

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.
