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.
