Service bulletin LI82.35-P-079531

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Complaint To prevent the wiper motor from overheating, the wipe frequency is reduced automatically when a dry windshield is detected. In specific situations under various independent ambient conditions, this detection could be activated by mistake, with the result that the wiper system switches from activated continuous operation to intermittent operation when it's raining. Cause Sensitive parameters for detecting dry conditions. The wiper system might switch back to intermittent operation even though it is raining and continuous wiping is activated. Remedy Install new wiper motor assembly. In the new wiper motor system, the parameters for detecting dry conditions have been optimized.
