Hoping to repair a headlamp issue this weekend on our 2019 GMC Sierra 2500HD. The passenger side low-high beam light is visible when you look in the assembly but it doesn't shine or light up the road. We tried to adjust the lamp by moving it up with the turn screw with no change. Hoping the D5SC1 new unit will correct the problem. Does anyone know of have a video on how to remove the old assembly?
