2008 Chevrolet Trailblazer Lighting Problems

While driving home at approximately 9:30pm, my eighteen year old daughter experienced the headlights failing to come on after dark with the automatic headlight-on feature. She turned on the headlights manually, and the low beams still were not working, but all driving lights and high beam headlights were working. I assumed that the bulbs were burned out, so replaced both the driver and passenger side bulbs. The low beam headlights still failed to come on either automatically or manually. I Googled the problem, and multiple people have reported this exact same problem, and some stated that there was a recall due to this problem. I am unable to find either a recall or a service bulletin for this issue.

DIM HEADLIGHTS QUIT WORKING WHILE DRIVING AT NIGHT. BRIGHT LIGHTS WORKED, BUT NO DIMS.

I WAS DRIVING IN THE EVENING AND BOTH OF MY HEADLIGHTS CUT OFF AND WON'T COME BACK ON.

I WAS DRIVING MY CAR AT NIGHT AND THE HEADLIGHTS JUST WENT OFF. NO WHITE LIGHTS ONLY THE AMBER LIGHTS WERE ON, THE NEXT DAY WHEN I TURNED THE CAR ON THE LIGHTS WERE WORKING. THIS HAS HAPPENED 3 TIMES. I AM AFRAID TO DRIVE THE CAR AFTER DARK.

LOW BEAM HEADLIGHTS GO OFF INTERMITTENTLY WHILE DRIVING. UNABLE TO GET THEM TO COME BACK ON MANUALLY. COMES ON AND OFF AS IT PLEASES. HAVE ALREADY REPLACED THE HEADLIGHT RELAY TO NO AVAIL.
