Two problems related to headlights turn off while driving have been reported for the 2009 Chevrolet Trailblazer. The most recently reported issues are listed below.
While driving at 30 mph, low beam headlights went out. High beams functioned and fog lamps functioned. Drove app. 5 miles and pulled off road and turned the car off. Turned the car on and the lights still did not function. Left the car for 2 hours and returned. Started the car and lights went on for 1 mile and then went off again. The lights went on again the following day for less than a mile of driving.
The headlights have failed. All the lights blink while you ride along. The two back doors will not lock or unlock and the front doors are starting to not lock or unlock properly. The items that let you know when a tire is low in air are failing. The last one costing over $100 to fix. I am getting very upset with the electric parts in this Trailblazer. This has been going on since purchase. As a photo I can send you a photo of the vehicle.
