Hello everyone,

I am having problems with the blower on my 2007 Silverado 1500 classic. I have found in another forum that GM released a (TSB) Technical Sevice Bulletin about the problem. It is TSB # 11046. I cannot find the site where this information is at. I want to find the site where it is listed to take it to my dealership. Someone copied and pasted it in another forum. It states that the repairs are to be made at no charge to the customer. That the vehicle is covered for 10 years from original date of service or 150,000 miles whichever comes first regardless of ownership. Does anyone know where I can find this article? I have searched the GM website and cannot find it. If anyone know where it is and can provide me with a link it would be great. Thanks to anyone who can help.

Even with a TSB in hand, the dealership will still need to do a diagnostic of the problem to determine if the TSB is applicable to your situation... if it is, then you're all good, if not you will be responsible for the diagnostic fee usually a 1 hr of labor charge or about ~$100....
Work with the dealership service department, don't go waving a TSB at them demanding it be fixed for free unless you already know and have written proof from a certified shop that the TSB applies to your EXACT problem...

Here is the text of the TSB that I found

My friend loaned me his 2003 suburban to test drive it for a couple of weeks before purchasing it.
About 20- 30 minutes on the highway with the blower on high, there was a very strong burning plastic smell. I turned off the fan and the smell dissipated. I tried the same thing the next day with the same result. I checked several websites online and it's a common problem due to a defective Blower Module Connector.
I believe the part number is 19260762, costing $113.88 for the part and $260.00 parts and labor.
I called the Service Department at Grossinger Chevrolet in Palatine, IL and he said GM Service Bulletin 11046 does not apply to my VIN and that bulletin is from Canada.

bulletin #10240A should cover it.

tech2,

The 2003 Suburban has low miles but doesn't meet the 10 year requirement in the SB.
I missed that requirement the first time I read it.
$260 seems reasonable considering the cost of the part and the temperature in my garage in Chicago ;-)

Thanks for your expertise
