Headlights went off on three different occasions this past week, it also happened once before several months back. They just shut off and while your panicking and hitting the headlight switch several times they finally come back on. We will not drive it at night anymore. Why is my car not recalled when others from the same year are. I have been working in manufacturing for over thirty years and my dad worked on the gm assembly line for thirty years. Don't kid yourself that you know which batch of parts were used on a particular car. My VIN is defective.

Headlights cutting out (completely off) at night while driving vehicle in a normal fashion and during good weather conditions with all interior lights off except gauges in dash display. No secondary lights or electronics on and on a dark road with very limited street lighting and while driving at 45mph. Able to regain lights by turning switch through full range a couple of times and putting on manual mode. Light sensor on dash is unobstructed.

My low beam headlights won't come on. I've replaced the relay switch, fuse once already. Fine for a short time now they're not working again.

My headlights keep going out while driving. I have replaced the bulbs and the relay switch. They will work for a while and then will go out again. Sometimes they will come back on. I cannot drive my vehicle at night with no headlights. The bright lights will work once in a while. This has been an ongoing problem for a few years. I have not been able to get my lights back on and no one seems to know what the problem is. This is a big safety issue and I see that there are many others with the same complaint. Gm needs to do something to fix this issue. The 2005 seems to big a big issue and a recall should be issued for the safety of all drivers and passengers. The date I selected below for when this happened is the most recent.

The headlights go out without any warning, I can't seem to turn them back on, I have to pull off to the side of the road, I tun the switch on and off and nothing happens, I've had the fussed and headlights changed and I can't seem to find a solution. The seem to just go on and off on their own. This if a very dangerous issue and I have found out I am not the only chevy owner that this is an issue with this model and I's surprised to find out there has not been a recall for this unsafe defect!.

This vehicle has the same problem with the headlight relay. The headlights go out on dim occasionally. The lights will also stay on when the switch in shut off. They will also come back on after going off when the switch is off. There is an active recall for 2006 models with this issue but none for the 2005. This occurred while driving the vehicle.

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!.

On June 11 2016 at 5:00am while driving my headlights went out, I used my high beam to return home from by pass highway 15miles. Once home tried the manual switch to see if lights would come on . No low beam but high beam worked. Couple of days later at dealership they could not find anything. I notice on occasion the low beams were not on when driving with the daylight running lights when I pull behind a car I would switch to high beam which did work. On 18oct 2016 time 7:45 the lights low beam did not come on when starting my truck. I tried the high beam and it worked. Had to drive 10 miles on city street to get home on high beam. After getting home I played with switch switching from manually to running the low beam came on afte I turned the car off and back on with light on the manually position. Please help dealer can't find the issue or duplicate it neither can I. . I travel alone and female I can't have this happening. I have to get repaired. On.

Passenger low beam headlight has gone out several different times over the 5 years we've owned it. Had a relay switched out that helped for a little bit. Also had to change the wiring right by the headlight because it was burnt up. We took it to chevy in devils lake, nd. I seem to notice other Trailblazers driving around with the same headlight burnt out.

While driving on a smooth hi-way (no vibrations) the low beam headlights went off. I switched to hi beams and pulled off the road at first opportunity. When I switched back to low beams and they worked perfectly. This has happened 4 times in the 11 years of ownership, twice in one week. Could never induce the problem.

The contact owns a 2003 Chevrolet Trailblazer. While driving various speeds, the headlights suddenly shut off and later turned back on. The headlights on/off switch was replaced, but the failure continued. The vehicle was taken to a dealer, but the failure could not be duplicated. The manufacturer was notified of the failure. The failure mileage was 120,000.

Solid state relay module for low beam - high beam headlights. When driving at night, both low beam headlights went out at the same time. Was able to switch to high beams to continue home, but not without blinding other vehicles. Replaced the solid state relay at a local autozone store. This relay is a single point failure, which an un-experienced driver could have had a possible accident if the person did not know what to do quickly in a calm manner.

The contact owns a 2006 Chevrolet Trailblazer. While driving at night, the headlights and high beam lights failed without warning. The vehicle had to be turned on and off several times in order for the lights to function normally and, other times, the lights would not turn back on. The contact stated that the electrical system in the entire vehicle would fail without warning and cause the vehicle to stall. The contact took the vehicle to the dealer where the driver's door switch was repaired per an unknown NHTSA campaign number. The vehicle was not diagnosed nor repaired for the other failures. The manufacturer was made aware of the failures. The failure mileage was 192,916.

At approximately 9:00 pm I was traveling on a rural road at highway speeds and suddenly my headlights went out. The headlamps were on low-beam at the time. I checked the headlight switch and it was in the proper position. I switched the headlights to high-beam and the lights came back on. I researched the issue and it appears that a 'headlight driver module' is to blame. This module appears to be a significant source of failure. This is a terrible design flaw. Something as important as headlights should not be subject to such a poor quality device. I would like to see no devices between the battery and the headlight switch and the headlight switch and the lights.

I started truck at night noticed no headlights . I had parking lights and my bright lights worked. I manually turned the light switch to off and on and still did not work. I had to drive a mile in town with my bright lights on to get home. But then the next day they were working again. This happened 9 day after I bought this vehicle. I took it back where I got it and they put in a fuse. I still have issues with the lights flickering and going dim and bright while I am driving also noticed the volt gauge moves around. . I am scared to death to drive at night and to even be able to travel any where out of town if they go out while I am driving. I or some one can be killed if the lights go out while im driving.

Headlamps failed while driving. Driver switched from high beam headlights to low beams. Nearly crashed when low beam lights failed to work. All other lamps functioning properly. After stopping, driver tried to switch the lights on and still failed. Only high beam lamps functioning. Vehicle can no longer be driven at night. I have been registered owner of this vehicle for past 5 years and was not notified of this recall by gm.

After leaving a movie theatre and upon entering the freeway June 13, 2015 at 12:30am, it appeared that the headlights were not on. I drove the vehicle, (with the high beams on) to the first available exit to pull over and found the headlights were not on and would not come on. I turned light switch on and off, turned the vehicle on and off and tried light switches again - this did not resolve problem. The high beams were still working. After leaving the high beams on for a while and trying the headlights again, they came back on. Approximately 2 months later, on August 8, 2015 while driving to the store, the headlights were not working again. I pulled the vehicle over tried the switch, tried turning the car on and off, again this did not resolve the issue. After driving with the high beams for about 5 minutes, I tried the headlights again and they came on. The same problem occurred two more times in the same week on August 11th and 12th, 2015 while driving at night.

I was driving home one night about an hour after dark. As I was driving about 45 mph, my headlights just completely went out without warning. After carefully pulling off to the side of the road I realized my high beams were still working. I looked into this issue and realized it was a relay 45 and 46 issue. The next day I replaced this relay and my lights worked. For a day. Now it's been almost a month, and I can't drive after dark. I've asked my local gm dealership to look into this and they told me there was a recall but yet they don't have a resolution. Being I work until the sun goes down, and I have an hour drive home from work 5-6 days a week, this presents a major problem for me. If this were a simple window switch recall (which I've already had replaced) I would be ok with it for now. Unfortunately this is a lighting issue which can be and is a very serious issue. I need this issue resolved immidiatly and if the dealership can't fix it, I don't know how I would be expected to.

I was driving down the road at night close to my house when the low beam headlights went off completely. I tried switching them on and off with the switch to no avail, but found that the high beams do work. There were many instances in the past where I was driving at night and thought that the lights had flickered, but wasn't completely sure until this happened. I called my local chevy dealer today, and the woman told me that she could not find a recall or even a technical service bulletin after I told her the problem I was having.

The contact owns a 2007 Chevrolet Trailblazer. The contact stated that while driving at approximately 55 mph, the headlights flickered. The vehicle was taken to a dealer where it was diagnosed that the relay switch needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The approximate failure mileage was 129,000.

Approximately 2 years ago my dim headlights went out as I was driving at night. I thought to switch to high beams and luckily they worked on high beam thank goodness this was a road I knew well. . I have no way of knowing how often this happens during the daytime. But it occurred several times after this. I had my vehicle checked and was told it was a relay. Changed it and problem solved, until now. The issue is back, gm sent me a "special coverage" letter, I called the number on the letter and was directed to take it to a chev. Dealership to confirm my vehicle does have the headlamp driver module issue then Chevrolet will let me know what would be next. They did confirm my vehicle has the issue but Chevrolet will not cover my vehicle because it is over the mileage of 150,000. Really? is my vehicle no longer worth fixing or is the issue supposed to resolve itself after the 150,000 mile mark? a salesman called me after I left the dealership to ask about me trading or getting rid of my vehicle, is this a ploy just to sell vehicles?.

The contact owns a 2006 Chevrolet Trailblazer 360. While operating the vehicle, the low beam headlights would suddenly shut off. The contact indicated that the failure was intermittent and, in some instances, the high beam lights malfunctioned. The vehicle was taken to the dealer who replaced the multi-function and headlight switches, but the failure persisted. The recall notice for NHTSA campaign number: 14v755000 (exterior lighting) was received in January of 2015. After contacting the dealer and the manufacturer, the contact was informed that no repairs would be performed because the failure was not present while the vehicle was at the dealer. The failure mileage was 220,000.

Both rear break lights failed simultaneously, even after fuses were checked both under the hood and behind the drivers side fuse box (fuse #12 & fuse #34). This is a road hazard and faulty wiring should be covered. Front left headlight was found to have switch with melted wiring as well, changes by mechanic and I was informed it could have caused a fire. This vehicle has 3 recalls thus far that are extremely dangerous if such faults can cause a fire within the electrical wirings. I would like to get compensated for the work done, the break lights faulty wiring should be covered under the recall as the local chevy dealer refuses to fix it.

The contact owns a 2006 Chevrolet Trailblazer. The contact stated that while driving at various speeds, the headlights would turn off and on intermittently. The contact mentioned that on a different occasion, the low beam lights failed to turn off causing it to over heat and catch on fire. The vehicle was taken to the dealer. The technician diagnosed that the relay switch was defective. The manufacturer was made aware of the failure. The failure mileage was 100,000 and the current mileage 101,000.

The low beam relay switch went out which made my headlights totally go out. No one could see me and I could not see the road.

The headlights will turn off while the vehicle is in motion for no apparent reason. This has been occuring for several years. You can switch to the high beams and the high beams will work. After about 10 to 15 minutes of driving, you can put the lights back to normal and they will operate on the low beams. It may be a month before this occurs again.

The contact owns a 2004 Chevrolet Trailblazer. The contact stated that while driving approximately 75 mph the low beam headlights suddenly failed. The contact quickly turned on the high beams and continued to drive the vehicle. After stopping the vehicle the low beams lights were switched back on and operated as normal. The contact indicated that the failure occurred on multiple occasions. The vehicle was not diagnosed or repaired. The manufacturer was informed of the failure. The failure mileage was 84,000.

2006 Chevrolet Trailblazer lt. While driving at night, lowbeam headlights go out. Happens at various speeds, happens sporadically. This has occurred 2 times before. The times before was in September 2010 mileage unknown at the time while driving in my neighborhood. Then on October 08, 2010, at 91,164 miles while driving home on the interstate at 70mph in the occurances in 2010 lowbeam headlights went out while driving, then independently re-illuminated within seconds. The latest occurance happened on April 16, 2011 at 10:50pm. I had just driven vehicle 20 minutes earlier and had no problems. My wife used the vehicle at 10:45pm and lowbeam headlights went out while driving at 40-45mph. She stated it took repeated tries with headlight switch to get the lights to re-illuminate. Wife pulled turnsignal arm back and highbeam lights would illuminate the flash to pass feature. No other electrical problems present. This happened while driving in neighborhood at low speed. This is a condition that could be very dangerous at highway speeds. This vehicle has automatic headlights, they come on automatically at dusk, and the headlight switch is left in the automatic mode and never touched. I have owned this vehicle since 19,000-20,000 miles, was a gm executive/demo vehicle.

I bought this car about 4 years ago and it has been nothing but an elecitrical mess. First my head lights would go out once a month, then a couple times a month, then once a week. My brake lights started doing the same. Our famliy mechhanic couldn't figure it out, he just kept replacing them and sending the bad bulbs in for warranty. A couple times the pigtails and lamps had to be replaces. Also 3 seperate occasions both headlights went out at once while driving. And I had to drive home in the dark with no head lights on. I took it the chevy dealership after the third time abd apparently my fuse box was melted and needed to be replaced. Spent over 1000. 00 doing that and it worked okay for about a year. Then headlights started going out again and brake tlights as well. Not once a week, but still about once a month or every other month. Recently my drivers window stopped working and I couldn't control the master switch to lock my car or roll up my windows. The cluster panel in the door needed to be replaced. Also, had two sensors that needed to be replaced because my 4 wheel drive, parking brake, and crusie control would stop working all at once and the lights would be lit up on the dashboard. I wasnt' able to use any of them until the sensor was replaced. Also the power shorted out in my side mirros, so I can't adjust the mirrors with the control or they start tiliting back and forth like crazy on their own. I have to get out of the car and adjust them manually. Gm needs to do a recall, this car is not safe and I will not be buying a gm car while I look for a new car soon.

I have a 2004 chevy Trailblazer; while driving on the highway; all guages, lights, etc. Abruptly stopped working and continue to not work. I researched on line and found it could be what is called the "cluster board". I took my vehicle to a local chevy dealer in daytona beach FL. They insisted it was the ignition switch. They replaced that mechanism for just under $300. The following week (this occurred in 2010); the exact same situation recurred; so I brought it back to the dealer and they then agreed it was the cluster board which would now cost me close to $700. 00. In order to avoid being ripped off to the tune of almost $1k; I purchased a gps unit so I could at least monitor my speed. The speed/rpms never register correctly; however, so far the other guages seems to be ok (except for the oil pressure, it goes out of whack frequently so I just bring it in quickly to make sure I have sufficient oil and that it's clear/clean). Most recently my headlights just go out without warning; I am able to use the high beams, but of course that puts me in jeopardy of getting a ticket. There are so many complaints on the 2004 chevy Trailblazer - I do not understand why there has not been a recall on the cluster board and the electrical issues (lighting). I cannot afford to have all the repairs completed and would like to see Chevrolet take on some responsibility for the cost of these flaws in the manufacturing of this vehicle.
