“I was driving down the road and all of a sudden my headlights go completely out. No other lights went out I continuously flicked them back and forth and finally my bright lights works to get me home. Next day they work fine again then 2 days later same thing happens. Bulbs fuses all have been changed and no short found. So I look online and seems a lot of people with trailblazer are having the same issues.”
