Having trouble with your Trailblazer’s automatic headlights? You are not alone. Automatic headlights are a convenient feature for many vehicles, but when they malfunction, they can be a nuisance and even a hazard. But that is not for you to worry too much.
In this post, we will take a look at potential causes for Trailblazer automatic headlights that aren’t working properly. We’ll begin by discussing the basics of Trailblazer automatic headlights and how they work. Next, we’ll review some of the common causes of non-functioning Trailblazer automatic headlights. We will also explore some tips to help you best diagnose and repair the issue.
Can a blown fuse cause your trailblazer headlights not to work?
If you are having trouble with your Trailblazer Automatic Headlights Not working, then a blown fuse could be the cause. Your Trailblazer’s headlight fuse is located in the engine compartment, and if it’s blown, the headlights will not work. To check whether or not the fuse is the issue, you will need to remove the fuse and inspect it for signs of wear or damage. If it looks worn or damaged, it is likely the issue and should be replaced. If it looks fine, then the issue may lie elsewhere.
Why are my headlights not working but my high beams are?
This could be due to several possible causes. One issue could be a defective headlight switch, which could cause the low-beam headlights to fail while the high beams remain operational. Another possibility is a bad headlight relay, which could also prevent the low beams from functioning while the high beams remain unaffected.
A blown fuse could also be the culprit, preventing the low beams from working while allowing the high beams to remain functional. In any case, it’s best to take your trailblazer to a reliable mechanic for an inspection and repair.
Why are my trailblazer headlights not working on automatic?
If your trailblazer automatic headlights are not working, there could be a few things causing the issue. One common reason is that the headlight sensor may need to be adjusted. This sensor is located near the windshield and can be adjusted to detect light levels. Also, it is possible that the headlight switch is damaged or not working properly. The switches can become worn out over time, preventing the headlights from turning on and off automatically.
Finally, if the bulbs are not working, the headlights will not turn on. If any of these issues are causing the Trailblazer Automatic Headlights to not work, it is best to take it to a mechanic to get it fixed. Here are other possible causes of trailblazer automatic headlights not working:
- The low fluid level in the power steering system
- Faulty power control module
- Clogged or broken headlight wiring
- Faulty headlights sensors
- Loose headlight connections or corroded grounds
How to troubleshoot trailblazer automatic headlights that are not working
Troubleshooting the trailblazer automatic headlights can be done by checking the wiring and the sensor, and if necessary, replacing them. If the lights are not working, then it is likely due to a faulty wiring or a sensor that needs to be replaced. Furthermore, you can check to make sure the lights are not on and that the headlight switch is in the “Auto” position. If the lights are off and the switch is in the right position, then this might not be the issue.
The recommended solution to the trailblazer automatic headlight problem
Replacing the switch with a new one should be your first solution if you suspect a faulty headlight switch is a cause of your trailblazer automatic headlight not working.

If these solutions do not fix the issue, then you may need to replace the entire headlight assembly
