I REPLACED MY HEADLIGHT ON THE LEFT SIDE WITH ALL NEW BALLASTS AND THE LIGHT FAILED TO FUNCTION PROPERLY. I ASSUMED THE MODS WERE DEFECTIVE SO HAD MB REPLACE THEM AND THE SAME THING HAPPENED WITH THE NEW ONE.

NOW FOR THE DUMBEST QUESTION OF 2017, DO THESE THINGS NEED TO BE PROGRAMMED?? OMG IF THATS THE CASE THIS HAS COST ME OVER 2 WEEKS OF FRUSTRATION????
