Blower Motor Control Module 2006 GMC sierra

[mbecke2]

2006 GMC sierra SLE quad cab. Recently blower motor quit working. Think I narrowed it down to the blower motor control module. I ordered a new one off amazon.com for 95$. I want to make sure I dont put the new one it and blow it as soon as I hook it up because something else is wrong. Do I need to replace the wire harness that comes into the module?? The last thing I want to do is plug in the brand new module and burn it up immediately bc of a bone head mistake. Been there, done that!! Anything I'm forgetting? Thanks for any input!

Carefully inspect the harness connector at the module/resistor. If it shows any signs of being overheated from the high resistance, then replace it. Check the plastic cover for any signs of melting.

The resistor is probably the problem.

[bossier62guy]

Only problem is it's not a resistor.....not in the traditional sense anyway. I explained the wiring in the last post you made. If you've checked the wiring then you either have a bad control module, blower motor control processor or blower motor itself.

UPDATE: I got the new part which was not an exact replacement. I had to splice 3 wires from the harness into the existing wires from the control head. I hooked it up and it worked great. Only after a minute of running the ac, the metal fins on the back of the resistor/module were so hot you coulda fried an egg on it. Was wondering if all that heat is normal, or am I goin to fry the new part?? I took the truck out for a ride and the ac seems to be working great.

I hate to tell you guys but this is covered by GM under warranty - even if your truck is out of the warranty period.

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

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.

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

•Remove the blower fuses (Htr A/C & HVAC 1 fuses).

•Lower the close-out panel enough to gain access to the resistor module connector.

•Disconnect the connector from the resistor module.

Note: Connector replacement is required even if the connector was replaced on a previous service repair.

 

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

 

•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.

 

•Install the new connector. Use the yellow splice sleeves provided with the connector.

•Install the new blower motor resistor.

•Reinstall the fuses. Test the blower motor to make sure all speeds are functional.

•Reinstall the hush panel/close-out panel.

Customer Reimbursement

Customer requests for reimbursement of previously paid repairs for the condition described in this bulletin are to be submitted to the dealer May 31, 2012, unless otherwise specified by State law. Repairs must have occurred within 10 years of the date the vehicle was originally placed in service, or 150,000 miles (240,000 km), whichever occurs first.

 

All reasonable customer paid receipts should be considered for reimbursement. The amount to be reimbursed will be limited to the amount the repair would have cost if completed by an authorized General Motors dealer.

 

When a customer requests reimbursement, they must provide the following:

 

• A completed Customer Reimbursement Request Form. This form is mailed to the customer or can be obtained from the dealer.

 

• The name and address of the person who paid for the repair.

 

• VIN, original paid receipt confirming the amount of repair expense(s) that were not reimbursed, a description of the repair, and the person or entity performing the repair.

 

For US dealers:

If a reimbursement request is denied, dealers MUST provide the customer with an explanation, in writing, as to why the request was denied. GM expects all reimbursement requests to be properly resolved within 30 days of receipt. If the denial was due to missing documents, the customer can resubmit when the missing documents are obtained, as long as it is still within the allowed reimbursement period.

He doesn't have the manual HVAC system...

[AlaskanSilverado07]

Understood...have a very good hunting buddy who took his automatic system in and they replaced it under warrantly. I gave him the same info and Ron Carter Chevrolet said it was the same part, contacted GM and replaced it without so much as even an argument. Granted, its a simple part to replace and relatively easy but to each their own.

could some one tell where this information was found? I just want to be prepared when I go to the dealer.

 

Thank you!

Thank you!

just take the number in with you Mark ,theyve seen this before so dont worry about it

[bigdog7272]

Thank you!

Does anyone know where the parts that get replaced are located in the vehicle? My blower motor just quit last nite & the dealer is so backed up with recall work that they can't get me in til December.

I need my truck and can't really drive it without the blower motor working because of the cold snowy weather here. The dealer is willing to give me the parts and I'll install them.

 

Is the hush/ close out panel under the dash on the right side by the passenger footwell?

 

Thanks in advance

[gmtech4]

Yes

Got er fixed up and working. Was a bit cool doing it in minus 10 Celcius weather....
