What Owners Say About Their Trailblazer

A Melting Module Will Cause Chevy's Low Beam Headlights to Stop Working

I was driving home from a wedding on the interstate at 55 mph, and my headlamps failed. Everything went completely dark. After a panic, I was able to turn on my high beams, and they worked properly. I turned the car off, waited a few minutes, and turned it back on. The low beam headlamps worked then. Since the first incident, I have had approximately 10-15 other incidents of the same occurrence.

A Melting Module Will Cause Chevy's Low Beam Headlights to Stop Working

I was positive that my vehicle was included in the recent recall, but when I called my local dealer, I was advised that my vin number was not included. I don't understand, since the issue on the recall is exactly the issue that I am dealing with. I have had to limit my use of the vehicle at night for fear that the headlamps will fail. Side note - they have failed at night twice in the last week alone.
