04 trailblazer Why did the instrument panel gauges suddenly just stopped working causing battery to run down Jumped started and was working again Now not working?

You may have an electrical problem. need a professional tech to look at it. I just found out that it is a gauge cluster problem. This is not the first time I heard this as I did call the dealership and explained to the mechanic what was happening, he said and the same thing. It is not uncommon for this problem in trailblazers. If the gauges are not working, then your battery is not getting charged up.
