2008 Chevrolet Trailblazer: headlights failing or too dim

Filed Jul 22, 2021 · Lights · MA

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.

Low beams stopped working, took it to the dealer who replaced both bulbs and it worked for a couple weeks now low beams randomly shut off while driving, especially at night. Airbag sensor keeps turning on and off and the horn stopped working. The airbag sensor seems to come on more on longer trips around the city with more turns.

I was driving down the highway and my lights just went off. The interior lights were on but the headlights went out. I stopped the car, turned it off, waited a few minutes and turned it back on. The lights did not come back on. The high beam lights still worked and I drove home with my brights on. When I got home and turned off the car I tried them again and this time they came on normally. This is the third time this has happened at night that they just went off.

While driving both of my headlights stopped working. This effected both daytime running lights and low beams. High beams are still operational. Researching the issue easily shows that the issue is a faulty headlight relay. I even tried to replace both bulbs and checked all fuses to verify. I contacted the service department of frei chevrolet in marquette michigan and they refused to even tell me if they had the parts in stock to resolve the issue. This will be the last time that I deal with them.
