Headlight low beams suddenly turned off while driving down the road at night. The first time it happened, they turned back on after a few seconds. The next year it happened, they stayed off until pulling over, turning off the car and restarting it. This problem has been reported by others on the internet, and seems to be restricted to the Chevy trailblazer and GMC Envoy. The reported fix is to replace the low beam relay.

2002 GMC Envoy headlights intermittent fluctuates and/or stop working (low beams only) while driving car at night. Occurs at all headlight settings, at all times of the day/night, almost every time the headlights are used and does not resolve itself upon trying car on/off. Problem started after warranty expired, approximately 2005. Gnc dealership and independent auto mechanics unable to determine source problem due to intermittent of problem. Problem continued until 2010 when low beam headlights finally went out completely and no longer worked at all. Fix was headlight module. Headlight module possibly damaged by voltage fluctuations coming elsewhere in vehicle electrical system. Old part is not available. Part was replaced at stuart GMC in stuart, Florida. The consequence is no headlights while driving at night so unable to drive car at night or worst, the danger of the headlights going out while driving (which happened all the time) and driving without headlights to get to your destination (without paying for a towtruck) can cause an accident or a citation. Another consequence is it decreases value of the vehicle and the fact that the vehicle cannot be honestly sold while this dangerous condition exists so I have been stuck with the car and cannot financially buy a new car without selling this car.
