\015\012On 1989-91\015\012vehicles, the headlights can be aimed using the adjusting screws\015\012located above and to the side of the headlight bulbs. A rough\015\012adjustment can be made while shining the headlights on a wall or on the\015\012rear of another vehicle, but headlight adjustment should really be made\015\012using proper headlight aiming equipment.
\015\012On 1992-98 vehicles, the\015\012aerodynamically styled headlights necessitate the use of headlight\015\012aiming kit 107-00003 or equivalent. The adjustable aimer adapters\015\012provided in the kit must be used to aim the headlights. Adjustment\015\012aimer adapter positions are moulded into the bottom edge of the\015\012headlight lens. Set and lock the adjustable adapters, attach each\015\012adapter to its mechanical aimer and aim the headlights according to the\015\012instructions in the kit.
\015\012Headlight aim adjustment should be made\015\012with the fuel tank approximately half full, the vehicle unloaded and\015\012the trunk empty, except for the spare tire and jacking equipment. Make\015\012sure all tires are inflated to the proper pressure.
\015\012The\015\012headlights must be properly aimed to provide the best, safest road\015\012illumination. The lights should be checked for proper aim and adjusted\015\012as necessary. Certain state and local authorities have requirements for\015\012headlight aiming; these should be checked before adjustment is made.
\015\012\015\012CAUTION\015\012\015\012About once a year, when the headlights are replaced or any time\015\012front end work is performed on your vehicle, the headlight should be\015\012accurately aimed by a reputable repair shop using the proper equipment.\015\012Headlights not properly aimed can make it virtually impossible to see\015\012and may blind other drivers on the road, possibly causing an accident.\015\012Note that the following procedure is a temporary fix, until you can\015\012take your vehicle to a repair shop for a proper adjustment.\015\012\015\012\015\012
\015\012Headlight adjustment may be temporarily made using a wall,\015\012as described below, or on the rear of another vehicle. When adjusted,\015\012the lights should not glare in oncoming car or truck windshields, nor\015\012should they illuminate the passenger compartment of vehicles driving in\015\012front of you. These adjustments are rough and should always be\015\012fine-tuned by a repair shop which is equipped with headlight aiming\015\012tools. Improper adjustments may be both dangerous and illegal.
\015\012For\015\012most of the vehicles covered by this guide, horizontal and vertical\015\012aiming of each sealed beam unit is provided by two adjusting screws\015\012which move the retaining ring and adjusting plate against the tension\015\012of a coil spring. There is no adjustment for focus; this is done during\015\012headlight manufacturing.
\015\012\015\012Because the composite headlight assembly is bolted into position, no\015\012adjustment should be necessary or possible. Some applications, however,\015\012may be bolted to an adjuster plate or may be retained by adjusting\015\012screws. If so, follow this procedure when adjusting the lights, BUT\015\012always have the adjustment checked by a reputable shop.\015\012
\015\012Before removing the headlight bulb or disturbing the headlamp in\015\012any way, note the current settings in order to ease headlight\015\012adjustment upon reassembly. If the high or low beam setting of the old\015\012lamp still works, this can be done using the wall of a garage or a\015\012building:
  1. \015\012\015\012 Park the vehicle on a level surface, with the fuel tank about\015\012 1\015\012 /\015\012 2\015\012full and with the vehicle empty of all extra cargo (unless normally\015\012carried). The vehicle should be facing a wall which is no less than 6\015\012feet (1.8m) high and 12 feet (3.7m) wide. The front of the vehicle\015\012should be about 25 feet from the wall. \015\012
\015\012\015\012\015\012 See Figure 6\015\012
\015\012\015\012\015\012Fig. 6: Example of headlight adjustment screw location for composite headlamps\015\012
  1. \015\012If aiming is to be performed outdoors, it is advisable to wait\015\012until dusk in order to properly see the headlight beams on the wall. If\015\012done in a garage, darken the area around the wall as much as possible\015\012by closing shades or hanging cloth over the windows.\015\012
  2. \015\012
  3. \015\012\015\012 Turn the headlights\015\012 ON and\015\012mark the wall at the center of each light's low beam, then switch on\015\012the brights and mark the center of each light's high beam. A short\015\012length of masking tape which is visible from the front of the vehicle\015\012may be used. Although marking all four positions is advisable, marking\015\012one position from each light should be sufficient. \015\012
\015\012\015\012\015\012 See Figures 7 and 8\015\012
\015\012\015\012\015\012Fig. 7: Low-beam headlight pattern alignment\015\012
\015\012\015\012\015\012Fig. 8: High-beam headlight pattern alignment\015\012
  1. \015\012If neither beam on one side is working, and if another like-sized\015\012vehicle is available, park the second one in the exact spot where the\015\012vehicle was and mark the beams using the same-side light. Then switch\015\012the vehicles so the one to be aimed is back in the original spot. It\015\012must be parked no closer to or farther away from the wall than the\015\012second vehicle.\015\012
  2. \015\012
  3. \015\012 Perform any necessary repairs, but make sure the vehicle is not\015\012moved, or is returned to the exact spot from which the lights were\015\012marked. Turn the headlights ON\015\012 and adjust the beams to match the marks on the wall.\015\012 \015\012
  4. \015\012
  5. \015\012Have the headlight adjustment checked as soon as possible by a reputable repair shop.

Hope thats helped (remember rated this) Good luck.
