Fog Light Switch problems of the 2004 Chevrolet Trailblazer

Driving conditions dark, 11pm, unlit, stars visible paved country road with hills, curves and 2-5 foot ditches. Weather wet but drying. Visibility good. Vehicle in motion near legal speed limit 80 km/hr. Occasional oncoming traffic, so occasionally switching between low and high beams. Noticed low beam headlights flickered occasionally. Effect was only visible after oncoming traffic had passed, before switching back to high beam headlights. I had attributed the effect to my eyes adjusting after the oncoming headlights. On one occasion, after the oncoming vehicle had passed, I switched back to low beam setting, but the low beam headlights were not illuminating the road at all. All I could see was a small amount of yellowish light off to the sides of the vehicle from the other running lights, including yellow lights on the side-view mirrors. There was insufficient light to see any distance down the road, so I ceased to depress the accelerator pedal, and covered the brake applying gentle braking. I still had my fingers on the lever and was able to switch back to high beams after several seconds. Fortunately the high beams still worked. I brought the vehicle to a stop at the next available safe opportunity, to assess what had happened. All other lights, including the fog lights were working. I drove at reduced speed alternately using the fog lights and high beams. The low beams occasionally started working again. By the time I was home, they had ceased to work. I replaced the gm hdm module, and the low beams worked for a year or so until that module failed. There is a recall to replace gm hdm 15016745 with gm hdm 13506836 but the recall apparently does not apply to my 2004 model year. Nhtsa recall no. : 15v-519 manufacturer recall no. : 14291 I consider this to have been a severe life threatening event.

The contact owns a 2004 Chevrolet Trailblazer. The contact stated that the vehicle would not start and the only lights that would function were the fog lights and high beams. The vehicle was not taken to have the failure diagnosed or repaired. The manufacturer was made aware of the failure and offered no assistance. The failure and the current mileages were 91,000.

Starting June 17, 2008, the low beams on my 2004 Chevrolet trail blazer lt go out intermittently - the high beams, fog lights, hazard lights, and turn signal lights still work - only low beams causing problems. I keep my lights setting in the postion that they come on when I start my car. I consider this a safety factor. The lights will go out suddenly. I can only document one time that they went out during the day time, but have documented seven (7) times that the lights went off at night. The next space on this form asks for the approximate incident date - I put down the first time. As stated above this has happened seven times at night and at least one time during the day. I can only tell during the day time if I am stopped at a traffic signal behind another vehicle and I only have 2 traffic signals between my home and work. I took my car to sandy sansing Chevrolet, pensacola, florida, on June 23, 2008, they said they checked my car for three hours but could not find problem. I would need to bring it in when the lights go out. Unfortunately, the only time I could tell they had gone out during the day time, I was stopped at a traffic signal and before the light turned green, the lights came back on. (my 16 year old grandson was in the car with me and can verify that this happened. In fact he and another grandson was in the car on the night of July 1, 2008, when the low beams went out while I was driving down the road on the way home from the baseball game.
