Service bulletin 20-372

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.

The remedy is to remove and replace the front bedroom air conditioner control kit and remove and replace the two thermostats in the unit.
