What model are you driving what are your options or build up spec? Have you done anything to the vehicle that may have started the situation any updates any add-ons?

2016 gmc sierra denali fully loaded besides rear entertainment. I installed a light bar that had the trigger wire ran off the high beam just so I had to use my high beam to be able to turn on the lightbar other than that its stock
