2011 GMC serria 1500 having some wierd electrical problems

Asked by Dec 30, 2016 at 07:36 PM about the 2011 GMC Sierra 1500 SLE Crew Cab 4WD

Question type: Maintenance & Repair

Just recently my GMC Serria is having
some electrical issues. It started with just
the occasional flicker of headlights and the
radio would go off, and come back on
under a second or so. Next thing I know,
driving home the other evening, I dim my
lights for oncoming car, I brighten and my
instrument cluster goes crazy, my radio
quits, headlights flicker, transmission won't
shift, stableloc control cuts off, and my
door locks go crazy too! Checked the body
grounds and battery is new. Any other
suggestions? Any help would be
appreciated!
