Affected Component: VISIBILITY:WINDSHIELD WIPER/WASHER:SWITCH/WIRING

Summary

This bulletin announces a replacement wiper switch assembly to address customer concerns of the wipers not parking correctly or moving intermittently, even when the control switch is off. Testing revealed moisture being retained in a composition of soldering flux and grease used during switch manufacturing may be forced out under extreme high-temperature conditions. If this moisture causes intermittent continuity between terminals, a circuit may close and power the wiper motor. A special sealer has been applied to the soldered terminals of the switch?s printed circuit board during production to prevent this condition from occurring.
