They're the stock headlights I haven't looked at what kind they are. Yes I have a voltmeter

Ok guy, I'm getting beat up on this one. 2015 Silverado, headlights flickering and a few other strange electrical issues. I've done the following: - new battery -new alternator -cleaned up ground connections- 2 on the front near the tow hooks, 1 on the frame that goes straight to the battery, the ever famous G218 in the left corner of the dash -new negative battery cable -took to dealer that did "thorough check" and still found nothing Still have flickering headlights and if I hit my window up switch when the windows are already up all the electrical in the dash goes dead for a few seconds and comes back. I'm ready to set this thing on fire. Any advice is appreciated.
