It is possible that a fuse blew if the auto headlight and running light system quit working on a 2005 Chevy Trailblazer. It is also possible that the computer is not responding to the set-up mode for the lights to work properly.

The best way to test whether a light works properly is to turn it on. If it lights up, it is working. If it does not, check the power source and plug it into the wall or replace the batteries if necessary. If this does not fix the problem, try replacing the bulb.

Replace the light sensor, it is under dash, 22$ at auto zone, my head lights quit working at night, but brake ligjts & fog lights still worked
What is the nature of the problem? e.g. one light doesn't flash. No lights flash. How many individual lights/bulbs does the vehicle have where you are having trouble? Are all other lights, stop, turn, tail, on that part of the vehicle working properly?
Fuse should be marked and also control parking and tail lights
