Headlight Switch problems of the 2006 Chevrolet Trailblazer

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.

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 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.

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.

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 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 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 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.
