2015 Silverado Z71 no high beam headlights

brinkkl2000 · December 4, 2018

As the title suggests, I have a 2015 Silverado 1500 Z71 Crew Cab 5.3 with no high beams. The indicator on the dash does come on as it is supposed to, but no lights. I have checked one of the bulbs and the bulb socket has voltage coming to it. At this point I assumed the other side is the same way, but I did not do my due diligence as I probably should have on the other side. I have seen a few posts on this subject but most came during the posters warranty period and offered no real solutions. I have seen that the printed circuit board (PCB) could be bad and would need to be replaced. Is there any way to test the pcb? Can I get any new pcb for my year, or are they pretty specific? Is it something I can do myself, and if so, is there any reason it would have to go to a dealer to be flashed of some sort. Any help would be appreciated.

How did you test the bulb to make sure it was good?
