It is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by this notification under a sale or lease until the defect or noncompliance is remedied.
All involved vehicles that are in dealer inventory must be held and not delivered to customers, dealer traded, or used for demonstration purposes until the repair contained in this bulletin has been performed on the vehicle.
Condition
General Motors
has decided that a defect which relates to motor vehicle safety exists in certain 2006-2010 model year HUMMER
H3 and 2009-2010 model year HUMMER
H3T vehicles.
The connector module that controls the blower motor speed in the heat/vent/air conditioning (HVAC) system may overheat under extended operational periods at high and medium-high blower speeds.
If this condition occurs, there is the risk that the heat generated could melt the plastic surrounding the connector module, which increases the risk of a fire.
Correction
Dealers are to replace the female connector and harness.
Vehicles Involved
All involved vehicles are identified by Vehicle Identification Number on the Investigate Vehicle History screen in GM Global Warranty Management system.
Dealership service personnel should always check this site to confirm vehicle involvement prior to beginning any required inspections and/or repairs.
It is important to routinely use this tool to verify eligibility because not all similar vehicles may be involved regardless of description or option content.
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
Customer Care and Aftersales (GMCCA).
Please refer to your “involved vehicles listing” before ordering parts. This part will be on Order Writing control initially and all DRO’s (Daily Replenishment Orders) will cancel. Dealers can place orders CSO (Customer Special Order).
In emergency situations a dealer should place a SPAC case and the orders will be processed in the order received.

If this is not convenient for the customer, the customer may mail the completed Customer Reimbursement Request Form and all required documents to the GM Customer Assistance Center.
All reasonable and customary costs to correct the condition described in this bulletin should be considered for reimbursement.
Any questions or concerns should be reviewed with your GM representative prior to processing the request.

- Paid receipt confirming the amount of the repair expense, a description of the repair, and the person or entity performing the repair.
Important: GM requires dealers to approve or deny a reimbursement request within 30 days of receipt. If a reimbursement request is approved, the dealer should immediately issue a check to the customer and submit an appropriate warranty transaction for the incurred expense. If a reimbursement request is denied, the dealer MUST provide the customer with a clear and concise explanation, in writing, as to why the request was denied. The bottom portion of the Customer Reimbursement Request Form may be used for this purpose. If the denial was due to missing documents, the customer can resubmit the request when the missing documents are obtained, as long as it is still within the allowed reimbursement period.
Warranty transactions for customer reimbursement of previously paid repairs are to be submitted as required by GM Global Warranty Management. Additional information can also be found in Warranty Administration Bulletin 11-00-89-004.

For owners outside these areas, dealers should notify customers using the attached sample letter.
Dealer Recall Responsibility – For US and Export
It is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by this notification under a sale or lease until the defect or noncompliance is remedied.
The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject to a recall of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair.
A failure to repair within sixty days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time.
If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation.
To avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible.
In the recall notification letters, customers are told how to contact the US National Highway Traffic Safety Administration if the recall is not completed within a reasonable time.
Dealer Recall Responsibility — All
All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in dealers’ possession and subject to this recall must be held and inspected/repaired per the service procedure of this bulletin before customers take possession of these vehicles.
Involved vehicles must be held and not delivered to customers, dealer-traded, released to auction, used for demonstration, or any other purpose.
All GM Certified Used vehicles currently in the dealers’ inventory within the Certified Pre-Owned Inventory System (CPOIS) will be de-certified and must be held and remedied per the service procedure in this bulletin.
Upon submitting an accepted/paid warranty transaction in the Global Warranty Management (GWM) system, the vehicle can be re-certified for sale within the CPOIS system, or once again be used in the CTP program.
Dealers are to service all vehicles subject to this recall at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward.
Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer listing, are to be contacted by the dealer.
Arrangements are to be made to make the required correction according to the instructions contained in this bulletin.
A copy of the customer letter is provided in this bulletin for your use in contacting customers.
Recall follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter.
In summary, whenever a vehicle subject to this recall enters your vehicle inventory, or is in your dealership for service in the future, you must take the steps necessary to be sure the recall correction has been made before selling or releasing the vehicle.

H3T vehicles. As a result, GM is conducting a safety recall. We apologize for this inconvenience. However, we are concerned about your safety and continued satisfaction with our products.
Important:
|
| Why is your vehicle being recalled? | The connector module that controls the blower motor speed in the heat/vent/air conditioning (HVAC) system may overheat under extended operational periods at high and medium-high blower speeds. If this condition occurs, there is the risk that the heat generated could melt the plastic surrounding the connector module, which increases the risk of a fire. |
| What will we do? | Your GM dealer will replace the female connector and harness. This service will be performed for you at no charge. Because of service scheduling requirements, it is likely that your dealer will need your vehicle longer than the actual service correction time of approximately 40 minutes. |
| What should you do? | You should contact your GM dealer to arrange a service appointment as soon as possible. |
| Did you already pay for this repair? | If you have paid for repairs for the recall condition, please complete the enclosed reimbursement form and present it to your dealer with all required documents. Working with your dealer will expedite your request; however, if this is not convenient, you may mail the completed reimbursement form and all required documents to Reimbursement Department, PO Box 33170, Detroit, MI 48232-5170. The completed form and required documents must be presented to your dealer or received by the Reimbursement Department by February 28, 2017, unless state law specifies a longer reimbursement period. |
