Some 1988-1989 Eldorados before VIN breakpoint 603547, and 1988-1989 Sevilles before VIN breakpoint 802643 may experience streaking or poor performance from the "wet-arm" windshield washer system. This may be caused by the volume of windshield washer solvent delivered to the wet-arm wiper blades. During operation of the washer system, solvent is delivered only on the up-sweep of the wiper blades. To repair this condition a new washer control module, P/N 22087513 which is currently available from GMSPO, delivers solvent on both the up and down sweep of the wiper blade. Graphite wiper blade inserts, P/N 12337035, are also available to improve wiper performance.
P/N 12337035 is expected to be available on January 2, 1989. Until then, normal part orders will not be accepted by GMSPO. Only verifiable emergency VIP orders will be accepted. SPO will make every effort to obtain parts. All parts will be placed on 400 control to waive VIP surcharges. However, the part will be shipped premium transportation at dealer's expense. All other order types will be cancelled as incorrectly ordered while the 400 control is in place.
The washer control module is contained within the windshield wiper motor cover and cannot be replaced independently. To replace the wiper motor cover:
1. Disconnect the electrical connector.
2. Remove cover screws.
3. Remove the wiper cover.
To install the wiper motor cover assembly:
1. Install wiper cover in position.
2. Install wiper cover screws.
3. Reconnect electrical connector.
For warranty purposes use Labor Operation N3750 at .3 hour.
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.
