What could be the issue with the headlights on my 2015 GMC Acadia not working?

If both front lights on your 2015 GMC Acadia suddenly stop working, it’s likely due to a blown fuse in the engine compartment fuse box. First, check the fuse to see if it’s the issue. If the fuse is fine, try replacing the bulbs with 9012s for halogens or D3S for LEDs, as both types serve as a dual high and low beam. If the lights still fail to work after changing the bulbs - hang onto the replacements for later use - it's possible that the ballasts are to blame. Water may have seeped in and caused corrosion, although it’s unusual for both ballasts to fail simultaneously. Consider investigating the mechanical light switch inside the vehicle at this point.

    I've had my 2015 Acadia for about 2 months now. The main headlights and fog lights are not working, although the "halo" lights are still operational. When I turn the switch, I hear a clicking noise, but the lights remain off. Can anyone offer assistance or advice?

    All of my lights are functioning properly except for the hi/low beam lights. I have attempted to fix the issue by replacing fuses and relays, but that did not solve the problem. I am unsure of what to do next - should I replace both headlight bulbs?

    My incident occurred a week back, and it turned out to be a faulty battery. I also swapped out the bulbs because they seemed to be in poor condition.
