SUBJECT:
WINDSHIELD WASHER STREAKING OR POOR PERFORMANCE
MODELS AFFECTED: 1988-1989 ELDORADOS AND SEVILLES
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:
NOTE:
Always install cover assembly with the wiper in the park position and drive pin in the open area of the cam.
1.

2.

3.
