Having problems with your 2002 Chevrolet TrailBlazer ?
While driving after dark i heard a wierd beeping sound, then all of a sudden all of my exterior lights and dashlights turned off. My hazards still worked. I pulled over, turned the ignition off for a moment then restarted with all lights working again. What is wrong?
Wiggle ur ignition switch with ur lights on to see if u get any glitches, this checks ur ignition switch for wear, also eyeball ur battery an its connections to see if u have corrosion or even any loose cables at battery or around under hood fusebox. one other thing to check is to have a charging system test to chek alternator output an battery condition. good luck
