What owners wrote

Headlight plug melted and burned. Passenger side headlight goes out repeatedly prior to noticing burn damage. Three bulbs replaced since august 2005 prior to burn damage noted. There are several complaints of this that I can gather from a web forum that I visit concerning the trailblazer.

Reported at 35,000 miles, June 2006 Fire

Front headlight burned out in november 2005 replaced light bulb. Burnt out again went to dinsdale chevy to get replaced said that the wire was melted and burned and would have to be replaced. I asked how that could happen and they said it was probably a manufacturing defect. I asked if that means they would replace it and they said no it would cost $132 to repair. I couldn't afford that so I bought the part and had to wire it myself.
