Technical Service Bulletin # 10012
Date: 100311
Recall - A/C Control Knobs Break Prematurely
FMVSS NONCOMPLIANCE
Bulletin No.: 10012
Date: March 11, 2010
Subject: 10012 - Heating, Ventilation, and Air Conditioning Control Knob Fracture
Models:
2009-2010 Chevrolet Express
2009-2010 GMC Savana
Condition
General Motors has decided that certain 2009 and 2010 model year Chevrolet Express and GMC Savana vehicles fail to conform to Federal/Canada
Motor Vehicle Safety Standard 103, Windshield Defrosting and Defogging System. These vehicles were built with heating, ventilation, and air
conditioning (HVAC) control knobs that may fracture and spin on the control shaft. If this happens, the driver may no longer be able to control the
heating, cooling, and ventilation for the vehicle. If this condition affects the defrost system when it is required, it may decrease the driver's visibility, and
could possibly result in a crash.
Correction
Dealers are to replace all HVAC control knobs.
Vehicles Involved
Involved are certain 2009 and 2010 model year Chevrolet Express and GMC Savana vehicles built within these VIN breakpoints:
Important
Dealers are to confirm vehicle eligibility prior to beginning repairs by using GMVIS (dealers using WINS) or the Investigate Vehicle History
link (dealers using GWM). Not all vehicles within the above breakpoints may be involved.
For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address
information has been prepared and will be provided to US and Canadian dealers through the GM GlobalConnect Recall Reports, or sent directly to
export dealers. Dealers will not have a report available if they have no involved vehicles currently assigned.
The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration
data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly, you
are urged to limit the use of this report to the follow-up necessary to complete this recall.
Parts Information
Parts required to complete this recall are to be obtained from General Motors Service and Parts Operations (GMSPO). Please refer to your "involved
vehicles listing" before ordering parts. Normal orders should be placed on a DRO = Daily Replenishment Order. In an emergency situation, parts should
