--------------------------------------------------------------------------------

Condition
On some 2003-2006 model year Chevrolet Avalanche, Suburban, Tahoe; GMC Yukon, Yukon XL; and 2003-2007 model year Chevrolet Silverado and GMC Sierra vehicles equipped with a manual heating, ventilation, and air conditioning (HVAC) system (CJ3) or heavy duty heater (C42), the interface between the electrical terminals of the relay resistor module and the wiring connector that powers the module may be incapable of conducting higher current levels for sustained periods of blower motor operation. In addition, moisture and other contaminants may enter the fresh air intake plenum and contact the internal circuit of the module or corrode the terminals. If any of these were to occur, the relay resistor module or wiring connector could overheat and the HVAC blower may not function on certain blower settings or may be inoperative. This may be accompanied by a burning smell or smoke.

Special Policy Coverage Adjustment
This special coverage covers the condition described above for a period of 10 years or 150,000 miles (240,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership.

Dealers are to install a new blower motor resistor and resistor module connector. The repairs will be made at no charge to the customer.

For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after May 10, 2011, are covered by this special coverage and must be submitted using the labor operation codes provided with this bulletin. Claims with repair orders prior to May 10, 2011, must be submitted to the Service Contract provider.

Vehicles Involved
Involved are certain 2003-2006 model year Chevrolet Avalanche, Suburban, Tahoe; GMC Yukon, Yukon XL; and 2003-2007 model year Chevrolet Silverado and GMC Sierra vehicles equipped with a manual HVAC (CJ3) or heavy duty heater (C42).

Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using the Applicable Warranties section in the Global Warranty Management system.

Parts Information
Parts required to complete this special coverage are to be obtained from General Motors Customer Care and Aftersales (GMCC&A).

Service Procedure
Note: The resistor module connector and blower motor resistor will need to be replaced if one or more of the symptoms below is present.

•The HVAC blower may not function on certain or all blower speed settings
•A burning plastic smell or smoke may be present in the vehicle
•The HVAC blower may run continually with the ignition in the OFF position
Determine if one or more of the above symptoms is present. If required, refer to HVAC diagnostic information in SI. Refer to Resistor Module Connector and Blower Motor Resistor Replacement in this bulletin if one or more of the symptoms are present. Other HVAC repairs are NOT covered in this product safety special coverage bulletin.

Resistor Module Connector and Blower Motor Resistor Replacement
 1. Remove the blower fuses (Htr A/C & HVAC 1 fuses).
 2. Lower the close-out panel enough to gain access to the resistor module connector.
 3. Disconnect the connector from the resistor module.
Note: Connector replacement is required even if the connector was replaced on a previous service repair.

 4. Remove the tape from the wiring harness to expose the wiring.

 5. Cut the wires back far enough from the connector to eliminate any melted insulation on the wire.
Note: Use the old connector as a map for splicing the wires for the new connector. Be sure to use the correct crimping tool from the terminal repair kit J 38125. Use only Duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection.

 6. Install the new connector. Use the yellow splice sleeves provided with the connector.
 7. Install the new blower motor resistor.
 8. Reinstall the fuses. Test the blower motor to make sure all speeds are functional.
 9. Reinstall the hush panel/close-out panel.
Customer Reimbursement – For US
Customer requests for reimbursement of previously paid repairs to correct the condition described in this bulletin are to be submitted to the dealer by January 31, 2013, unless otherwise specified by state law. If this is not convenient for the customer, they may mail the completed form and all required documents to the GM Customer Assistance Center. Repairs must have occurred within the 10 years of the date the vehicle was originally placed in service, or 150,000 miles, whichever occurs first.
