Service bulletin TSB 424

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

There are a limited number of coaches since units built after 6/12/15 will not be affected and inventory not shipped were inspected prior to shipment. Issue: Increased noise level in Bedroom from a/c vent. Note: This does not affect the operation of the AC system, just the noise level.
