1. Park the vehicle on a level surface.
2. Make sure the tire pressures are correct.
3. The driver or someone who weighs the same should sit in the driver's seat.
4. Clean the outer lens so that you can see the center of the headlights.
5. Park the vehicle in front of a wall or a screen.
6. Turn the low beams on.
7. Determine if the headlights are aimed properly.
8. Measure the vertical adjustment height of the headlights (A). The lights should reflect 2.1 in (52 mm.) below headlight height (B).
9. If necessary, open the hood and adjust the headlights by turning the vertical adjuster.

I installed eagle eyes aftermarket headlights on my 99 Chevy Tahoe I need to know how to adjust them. I know there is 2 adjustment nuts on top is that what I use to adjust them?

Try the bulb itself. You can check it with a voltmeter set to continuity. Check the harness for a poor ground connection near the bulb socket. It will be a black wire under a screw head on the chassis. If nothing out of the ordinary is found, replace the headlight relay for that side. Each headlight has its own relay.

cant be fixed, you will need new headlights. Just google it.

if was easy everyone would do it

condensation is because theres no ventilation tube on the headlight, drill a 1/4 hole underneath each end of the headlight and problem solved.

Try to adjust the idle of the truck because there is a possibility the idle is low and if still not work put the gear in neutral and then start it and step on the gas pedals for 20 sec.

The weather seal is shot. Replace the entire assembley but don't forget to reconnect the turn signal bulb BEFORE you reinstall the assembley into the car body!
