Service bulletin LI83.40-P-071168

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.

In some operating statuses, a low-frequency (approx. 140 Hz) humming noise may be heard in the air conditioner housing. The air flow may be causing the seals of the flaps in the air distributor housing to vibrate. The air distribution box must be replaced.
