Low headlights (both) are off continuually. High beams are ok, no matter which position dash headlight switch is in. High beams come on with steering column control, but not low beams. Replaced relays and fuses although originals checked ok.. Removed each headlight nacell assembly and checked each light individually with separate source 12v. All ok. Meter checked hi-lo headlight plug, 12v ok on hi wires, no voltage on lo wires. Problem exist whether car is running or not. I am stumped!

Defect investigations
Driver's Master Power Window Switch
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.the federal safety agency.dot.gov/owners/Searchreference, see the attached list for ODI numbers.
EA12004
Driver's Master Power Window Switch
The Office of Defects Investigation (ODI) opened this investigation on February 9, 2012 in response to complaints alleging driver door module melting and/or burning in MY 2006-2007 Chevrolet Trailblazers. In response to ODI's Information Request letter, General Motors presented 167 reports and 698 warranty claims that related to the alleged problem. ODI has received a total of 83 complaints, 66 alleging the door module had melted or burned, and the remaining 17 stating that the window switches acted erratically or were inoperative. Twenty-eight of the reports received have led to driver door fires, some of which allege the vehicle was keyed off and unattended. Based on the agency's current analysis, ODI has upgraded its investigation to an Engineering Analysis (EA12-004) to determine whether the subject vehicles contain a defect that presents an unreasonable risk to safety.The vehicle models and production dates of affected vehicles will be evaluated, particularly other GMT360 vehicles. The ODI reports cited above can be reviewed online at www-odi.the federal safety agency.dot.gov/owners/Searchreference under the following identification (ODI) numbers: 10247838, 10260600, 10274337, 10275626, 10284010, 10396958, 10406203, 10409023, 10414691, 10417938, 10423865, 10426281, 10434446, 10445657, 10447754, 10447757, 10447770, 10447788, 10447813, 10447831, 10447865, 10447880, 10447892, 10447938, 10447994, 10447996, 10447997, 10448028, 10448086, 10448138, 10448176, 10448201, 10448337, 10448455, 10448464, 10448478, 10448540, 10448900, 10448941, 10449150, 10449166, 10449169, 10449236, 10449722, 10450055, 10450202, 10450284, 10451584, 10451878, 10451918, 10452197, 10452301, 10452586, 10452743, 10452895, 10453161, 10453227, 10453261, 10453578, 10453746, 10453951, 10454196, 10454211, 10454539, 10454673, 10455122, 10455150, 10455279, 10455469, 10456285, 10456529, 10457116, 10457644, 10457811, 10458224, 10458485, 10458599, 10458743, 10458846, 10460062, 10460141, 10460732, 10460843

Most recent owner complaints, unedited.
Tl* the contact owns a 2007 chevrolet trailblazer 360. While driving approximtaley 25 MPH at night, the low beam and high beam headlights failed to illuminate. The vehicle was maneuvered to the side of the road and parked at a safe location until the next day. The vehicle was taken to the dealer where the headlamp driver module was replaced. The VIN was not included in the federal safety agency campaign number: 15v519000 (exterior lighting). The manufacturer was not notified of the failure. The approximate failure mileage was 115,000.
Shortly after christmas 2015, while driving on a city street the red light on the gas guage came on and the gauge showed empty. Having just filled the tank earlier that day I thought the gas had been stolen. I pulled into a station to refill but it was still full. For the next five weeks the check engine light was on and the gauge only worked occasionally. It wasn't a dangerous situation but after a few weeks of guessing how much gas was in it, I took it to a repairman who replaced the fuel pump module assembly for a mere $767.04. The odometer is only at 47,760.

The manufacturer was not made aware of the failure and the VIN was not included in the federal safety agency campaign number: 15v519000 (exterior lighting). The failure mileage was 115,306.
Headlight fail - they intermittently turn off by themselves while driving and eventually turn back on. This happens very often and I am very afraid of my safety and also of my family.
Low beam headlights will not work. Only high beams. Began intermittently but now will not work on low beams at all. Took to dealership and was told this was not listed under the recall however it is the exact problem.

Started the trailblazer and headlights would not come on.. Tried automatic and manual. We turn the trailblazer off and on a couple times and finally got it to come on maunual. One week later was coming home on a 4 lane and my healights just went off. Luckey I was able to get off road and turn flashers on. Turn trailblazer on and off, the headlights on and off but they didnt come on . Turn automatic lights off and turn high beams on that is how I had to drive home. I tested my lowbeams on and off coming home. The would go in and out.
