Service bulletin 122-V7Z9N-07

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

Instructions for carrying out Workshop Campaign WKC6, Re-programming Air-Conditioning Control Unit and Various Other Control Units. Due to incorrect servo motor control, the air-conditioning system flaps on the affected vehicles may not be moved to the required positions at times. If this happens, the temperature distribution and air distribution in the interior of the vehicles can differ from the selected settings. To prevent this from happening, the air-conditioning control unit must be re-programmed with an updated data record. The software of other control units will also be updated at the same time.

Listing a model year does not mean every vehicle of it is concerned: the document says which.

A recall listed here may apply to some of the same vehicles. Only the manufacturer can say whether it applies to one vehicle.
