Riviera V6-231 3.8L VIN C SFI (1989)
Windshield Washer Control Module: Customer Interest
Wipers - Washer Streaking or Poor Performance
Corp. Ref. No.:
WINDSHIELD WASHER STREAKING OR POOR PERFORMANCE - REPLACE WASHER CONTROL MODULE AND WIPER
MODELS AFFECTED: 1988-89 RIVIERAS AND REATTAS
Some 1988-89 Rivieras and Reattas produced before the VIN breakpoints KH402818 and KB900906 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 (part number 22087513) which is currently available from GMSPO, delivers solvent on both the up and down sweep of the wiper blade.
Graphite wiper blade inserts will also be available to improve wiper performance, part number 12337035.
