Posting in hope that a newbie like myself will have a shorter path to locating and adjusting their headlights. If only it was as easy as popping the hood and reaching in. The metal framework that holds the radiator and front end together totally blocks the task from above. I did the drivers side and it take you 5-10 minutes.
Basically you turn out the wheel
Remove 3 screw and a pop rivet
Reach up from underneath
Use a small 8mm wrench
Clockwise moves the beam down
