My 2016 trax has a light situation. Everything was fine. Then the turn signals started flashing fast. Figured bulbs out. Nope, all test fine. Still. Passenger side marker lights do not work, drivers side rear turn signal light does not work and drivers side drl and low beam head light do not work. I had someone say check alternator. 15.10 volts at idle. ... fuse? If so which one, ground? Any idea where to start looking? I wonderd if it could be infotainment system related. Or headlamp switch? Im a first responder, i need lights and fast. Any help appreciated. It is out of warranty.
