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.

Owners of these vehicles have filed 172 complaints in the electrical category.
