Question about 2004 Chevrolet TrailBlazer
Thanks for choosing FixYa and welcome. If they both went out at the same time, you need to check your wiring harness. Check the wires with a voltage meter and see which ones are not getting power. Check for loose connections and make sure all ground wires are grounded properly. The grounds will be black. If they didn't go out at the same time, as for the brake lights, you may have a bad brake switch. It is located above your brake pedal. As for the low beam lights, it may be your actual light switch that is broke. Always be sure to unplug your battery when working on electrical wires. Thanks for using FixYa and have a good night.
