Electrical problem
2003 GMC Yukon V8 Automatic

how do i adjust the headlights left to right/ up & down on my 2003 yukon denali xl - Also what could be making my service ride control light come on. I already installed a new air compressure & new tires. although i need to have the tires balanced agian, car shakes when speeds reach 60 or above, would this effect my ride control system.

As for adjusting your headlights, there should be 2 hex head bolts sticking up aboive your lights under the hood. One adjusts up and down the other left to right.

As for youre tires, you need to have them balanced. As precise of controls these newer vehicles are now any little thing can make those lights come on.
