Has anyone been able to resolve the flicking warning lights coming on and off issue. I have a 2007 Chrysler 300 and have encountered this several times. However, the last time this occurred the whole dashboard went black and the head lights and taillights went off while driving on highway. I had to pull over and turn to car off and restart it to get it to work.
I am sure that someone has had this problem on many different vehicles. But the chance that someone will see your question and have the same cause is slim. If you don’t think you can fix it then just tell a good shop what it is doing . Of course the first step would be to check the battery cables for corrosion and tightness.
others with your year and vehicle had this done and fixed the problem
