Have a 2015 suburban and the headlights are awful. Factory HID and they point right to the ground. How do they adjust or can they be at all. I have looked and looked and cant find how to adjust them. Please help

 

This video isn't Chevy specific but I'll wager it will help you to find your headlight adjustment procedure:

 

I know how to aim headlight . I can find the adjustment screws on the backside of the headlight

 

Are they true hid's bulbs. chevy put halogen bulbs in the hid lens on lower end trim lines. even when aimed properly they suck. chevy had a recalibration for the bcm to increase the pwm output.

 

They are true HID I check and it's the LTZ trim. They shine to much on the ground right in front about 8-10 feet in front

 

Listen to what advice tech2 says, Antonios, He is a real professional working mechanic/technician who knows more about the newer things on later model vehicles then I do by far. .

I think I am out of my depth here since I am used to the old-school headlights, most of them still made of glass, which adjusted from the front of the vehicle.
