Some 1988-89 Toronado models built before VIN KU301518 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 will also be available to
improve wiper performance, P/N 12337035.
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.
Install wiper cover in position.
2.
Install wiper cover screws.
3.
Reconnect electrical connector.
