Dashboard lights & gauges

Asked by Happymama2four Oct 29, 2020 at 04:53 PM about the 2007 Chevrolet Trailblazer LS 4WD

Question type: Maintenance & Repair

My dashboard and all the gauges and
warning lights all come on when I'm
driving. Sometimes it stops or isn't
happening all the time. My mechanic
can't get me in for two weeks!

1 Answer


Whacky things with the gauges usually point to the ignition switch. Pretty common, I keep a spare with me due to this. Use AC Delco brand, our platform can be picky with electronic parts. Less common problem would be a dashboard ground.
