Service bulletin 122-K4T2R-06

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.

There is the possibility that the relay for setting 1 of the engine-compartment blower is not inserted correctly in the relay carrier on the affected vehicles.
