I have a 2006 GMC envoy denali that caught fire this morning, it was an electrical fire, caused in the hvac blower circuit, the circuit fuse did not blow, the cabin filled with smoke, and an open flame was created. I managed to put the fire out, however someone else in this situation might not have even been able to pull off a busy highway, let alone extinguish the fire as it was under the dash behind the glovebox. the symptoms before the fire were as follows: 1)A faint burning electrics smell (electrical smoke IS very distinctive) 2)blower quit running(within 30 seconds of smell) 3)cabin filled with smoke (within 1 minute of smell) to the point I could not see out the windshield 4)open flame was present under dash (within 2 minutes of smell) the vehicle was in motion, 50mph, heating system was running, outside temperature 5* fahrenheit. this appears to be a common failure point as there are multiple repair kits available with new wiring connectors to replace damaged ones when replacing speed resistor there were no previous issues with the hvac blower motor system

Had problems with the heater's blower motor not blowing or sometimes blowing but not on every speed. Looked up issue on youtube and found many videos of the same issue and the videos showed them having to replace the heater's blower motor resister. As the resister was being replaced, we noticed the resister was melted onto the plug it plugs into and the thick red wire was also melted. Resister got replaced and the blower speeds all worked again. Shortly after installation of the new resister, the number 5 speed failed but all others continued. Three months later, the resister failed. Exchanged and replaced the resister again and worked on all speeds but 5 again. Had a smell to it while in use, we got use to it and thought nothing of it anymore. Worked for over 2 years until 1/12/2019 when as the envoy was in my yard warming up in below freezing temperatures, the vehicle caught fire without and warning and burned under the glove box catching the contents in the glove box on fire and making the vehicle burst into flames and even had an explosion inside the vehicle. Black smoke was pouring out on the area of the passenger side windshield wiper area. There was a hole in the windshield above the wiper.

I was driving to church on a major highway, it was raining and dark suddenly, my low beam lights went out. I stopped and turn the high beam on and when I turn the high beam off after 2 or 3 minutes the low beam came back on. The next day the same thing happened again on my way from work, driving down a city street and they just went off. I pull over and turn the high beam on and off for several minutes and they came back on. Really afraid now to drive at night. I used this vehicle for traveling on vacations, never had any problem with the lights until now.

The subject vehicles are model year (MY) 2002-2009 Chevrolet Trailblazer, GMC Envoy, 2004-2007 Buick Rainier, 2003-2008 Isuzu Ascender, 2005-2009 Saab 9-7X, 2002-2004 Oldsmobile Bravada, 2003-2006 Chevrolet SSR, 2005-2009 Buick Lacrosse, and 2006-2008 Pontiac Grand Prix. This scope includes the Trailblazer/Envoy variants: 2002-2006 Envoy XL/Trailblazer EXT and 2004-2005 Envoy XUV. The original scope of this investigation was expanded to include all vehicles equipped with the subject Headlight Driver Module (HDM). The focus of the investigation was to determine whether actions performed by General Motors adequately addressed any unreasonable risk to motor vehicle safety in the subject vehicles concerning the headlights and the HDM that controls them.Under normal electrical load and environmental conditions, the HDM can overheat inside the Underhood Electrical Center (UEC). This can cause the module to fail and result in a simultaneous loss of both low beam headlights and both daytime running lights (DRLs), often with no warning or prior detectability to the driver. This failure can be intermittent or permanent. No other exterior lights are affected. High beams, turn signals, brake lights, and reverse lights are still operational.General Motors addressed this issue with 2 recalls (14V755 & 15V519) and a special coverage program (N172091910). In view of the recalls and special coverage program implemented by GM and the vehicle high beams continuing to operate, ODI has tentatively concluded that the actions taken by GM mitigate any unreasonable risk to safety posed by HDM failure in the subject vehicles.Accordingly, the investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency reserves the right to take additional action if warranted by new circumstances.The ODI reports cited above are available for review online at NHTSA.gov under the identification numbers in the attached document.

On August 15, 2012 General Motors (GM) announced a regional recall action (12V-406) involving model year (MY) 2006-2007 Chevrolet Trailblazer, GMC Envoy, Buick Rainier, Isuzu Ascender and MY2005-2007 SAAB 9-7x vehicles originally sold or currently registered in the salt belt states of Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin, and the District of Columbia. The recall remedy requires the inspection and repair or replacement of the master power window switch, which GM refers to as a driver door module (DDM). At the same time, GM implemented a special coverage program to replace failed DDMs for vehicles registered outside of these states. ODI was not satisfied with GM's exclusion of non-salt belt vehicles and continued its investigation. On June 13, 2013, GM submitted a related recall notification (13V-248) to reclassify the initial special coverage program into a safety recall for vehicles that were not previously repaired under special coverage.The Office of Defects Investigation (ODI) opened Engineering Analysis EA12-004 on June 11, 2012 to further investigate allegations of DDM thermal incidents in model year (MY) 2006-2007 Chevrolet Trailblazer vehicles. Thermal incidents involve cases where fire-related events such as smoke and melt are present. ODI has received 170 reports alleging a thermal event occurred. Complainants stated that the DDM melted and in some cases produced odor and/or smoke. Fourteen of these incidents led to a fire where visible flames were reported or the damage extended significantly beyond the DDM. In addition to the 170 reports listed above, ODI received 63 reports alleging the DDM acted erratically or became inoperative. In response to ODI's Information Request (IR), GM provided 619 unique consumer complaints that related to the alleged problem. Seventy-seven of those reports led to a fire with flame, and 4 reported injuries of smoke inhalation and/or slight burns from contact with hot switches. GM also submitted 20,400 warranty claims for replacement of the DDM, most of which involved inoperative switches. The problem condition is caused by fluids, such as rain water, entering the driver's door module and subsequently causing corrosion that could result in an electrical short in the printed circuit board. A short may cause the power door lock and power window switches to function intermittently or become inoperative. However, the electrical short may also cause overheating that could melt components of the door module, producing odor, smoke or in some cases fire with flame. The circuit board was redesigned and GM implemented the new design into vehicle production on May 14, 2007. All failures cited above occurred in vehicles produced before this build date (i.e., with the original design DDM). GM also reported that all MY 2006-2007 GMT360/370 platform vehicles and MY 2005 SAAB 9-7x vehicles utilized the same DDM and therefore ODI expanded the subject population to include these vehicles.This investigation is closed on the basis of GM's announcement of safety recalls 12V-406 and 13V-248. The ODI complaints cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID, see the attached list for ODI numbers.
