Two problems related to headlights turn off while driving have been reported for the 2003 Chevrolet Trailblazer. The most recently reported issues are listed below.
I have a heavy fuel runoff , from my fuel tank. Even if the engine is only ran for a minute. Also, my headlights go out whenever they feel like doing so,while driving.
This has been going on for three years since 2011 at night at random times our low beam headlights go out on us as your driving down the highway. They may come back on before you get home but we have drove 1hr 30 minutes and still not. We did take it in serveral times and they can not fine a problem. They said they can change this n that senor but couldn't say that would even fix it. But cost us $$$$$$ why can't some one fine out do a recall we hate driving on our highbeam and so does the people we pass or get behind. We do try and turn them off when we pass other but that is dangers as well. Please help we want to keep our Trailblazer and stay alive.
