Where, exactly, are the headlight adjusters for the drivers side headlights?

The usual cause is a bad ground.
Check the ground with a test lamp.

bad connection or bad earth check all connection or bulb

I would check for the groundwire continuity

Here are directions....

1. Park the vehicle on a level surface, with the fuel tank about 1 / 2 full and with the vehicle empty of all extra cargo (unless normally carried). The vehicle should be facing a wall which is no less than 6 feet (1.8m) high and 12 feet (3.7m) wide. The front of the vehicle should be about 25 feet from the wall.

1. If aiming is to be performed outdoors, it is advisable to wait until dusk in order to properly see the headlight beams on the wall. If done in a garage, darken the area around the wall as much as possible by closing shades or hanging cloth over the windows.
2. Turn the headlights ON and mark the wall at the center of each light's low beam, then switch on the brights and mark the center of each light's high beam. A short length of masking tape which is visible from the front of the vehicle may be used. Although marking all four positions is advisable, marking one position from each light should be sufficient.

Fig. Fig. 9: High-beam headlight pattern alignment

1. If neither beam on one side is working, and if another like-sized vehicle is available, park the second one in the exact spot where the vehicle was and mark the beams using the same-side light. Then switch the vehicles so the one to be aimed is back in the original spot. It must be parked no closer to or farther away from the wall than the second vehicle.
2. Perform any necessary repairs, but make sure the vehicle is not moved, or is returned to the exact spot from which the lights were marked. Turn the headlights ON and adjust the beams to match the marks on the wall.
3. Have the headlight adjustment checked as soon as possible by a reputable repair shop.

Note: The headlights must be aimedcorrectly. Ifadjusted incorrectly they could blind the driver of an oncoming vehicle andcause a serious accident or seriously reduce your ability to see the road. Theheadlights should be checked for proper aim every 12 months and any time a newheadlight is installed or front end body work is performed. It should beemphad that the following procedure is only an interim step which willprovide temporary adjustment until the headlights can be adjusted by a properlyequipped shop. 1-Identify the exact location of the adjustment screws: a) On halogen bulb style headlights, theadjustment screws are located on top of the housing. b) On sealed beam style headlights, theinboard (vertical) adjustment screw and the upper (horizontal) adjustment screware accessible on the exterior of the vehicle. 2-There are several methods of adjusting the headlights. Thesimplest method requires masking tape, a blank wall and a level floor. 3-Position masking tape vertically on the wall inreference to the vehicle centerline and the centerlines of both headlights. 4-Position a horizontal tape line in reference to thecenterline of all the headlights. Note: It may be 'easier to position thetape on the wall with the vehicle parked only a few inches away. 5-Adjustment should be ,made with the vehicle parked 25 feetfrom the wall, sitting level, the gas tank half-full and no heavy load in the vehicle. 6-Starting with the low beam adjustment, position thehigh 1ntensity zone so it is two inches below the horizontal line and twoinches to the side of the headlight vertical line, away from oncoming traffic. Adjustmentis made by turning the top (sealed beam) or inner (aerodynamic type) adjustingscrew clockwise to raise the beam and counterclockwise to lower the beam. The adjusting screw on the side should beused in the same manner to move the beam left or right. 7-With the high beams on, the high intensity zone shouldbe vertically centered with the exact center just below the horizontal line. Note: It may not be possible to positionthe headlight aim exactly for both high and low beams. If a compromise must be made,keep in mind that the low beams are the most used and have the greatest effecton safety. Have the headlights adjusted by a dealerservice department or service station at the earliest opportunity -

AIMING THE HEADLIGHTS

On 1989-91 vehicles, the headlights can be aimed using the adjusting screws located above and to the side of the headlight bulbs. A rough adjustment can be made while shining the headlights on a wall or on the rear of another vehicle, but headlight adjustment should really be made using proper headlight aiming equipment.
On 1992-98 vehicles, the aerodynamically styled headlights necessitate the use of headlight aiming kit 107-00003 or equivalent. The adjustable aimer adapters provided in the kit must be used to aim the headlights. Adjustment aimer adapter positions are moulded into the bottom edge of the headlight lens. Set and lock the adjustable adapters, attach each adapter to its mechanical aimer and aim the headlights according to the instructions in the kit.
Headlight aim adjustment should be made with the fuel tank approximately half full, the vehicle unloaded and the trunk empty, except for the spare tire and jacking equipment. Make sure all tires are inflated to the proper pressure.
The headlights must be properly aimed to provide the best, safest road illumination. The lights should be checked for proper aim and adjusted as necessary. Certain state and local authorities have requirements for headlight aiming; these should be checked before adjustment is made.

CAUTION About once a year, when the headlights are replaced or any time front end work is performed on your vehicle, the headlight should be accurately aimed by a reputable repair shop using the proper equipment. Headlights not properly aimed can make it virtually impossible to see and may blind other drivers on the road, possibly causing an accident. Note that the following procedure is a temporary fix, until you can take your vehicle to a repair shop for a proper adjustment.
Headlight adjustment may be temporarily made using a wall, as described below, or on the rear of another vehicle. When adjusted, the lights should not glare in oncoming car or truck windshields, nor should they illuminate the passenger compartment of vehicles driving in front of you. These adjustments are rough and should always be fine-tuned by a repair shop which is equipped with headlight aiming tools. Improper adjustments may be both dangerous and illegal.
For most of the vehicles covered by this guide, horizontal and vertical aiming of each sealed beam unit is provided by two adjusting screws which move the retaining ring and adjusting plate against the tension of a coil spring. There is no adjustment for focus; this is done during headlight manufacturing.
Because the composite headlight assembly is bolted into position, no adjustment should be necessary or possible. Some applications, however, may be bolted to an adjuster plate or may be retained by adjusting screws. If so, follow this procedure when adjusting the lights, BUT always have the adjustment checked by a reputable shop.
Before removing the headlight bulb or disturbing the headlamp in any way, note the current settings in order to ease headlight adjustment upon reassembly. If the high or low beam setting of the old lamp still works, this can be done using the wall of a garage or a building:

1. Park the vehicle on a level surface, with the fuel tank about 1 / 2 full and with the vehicle empty of all extra cargo (unless normally carried). The vehicle should be facing a wall which is no less than 6 feet (1.8m) high and 12 feet (3.7m) wide. The front of the vehicle should be about 25 feet from the wall.

Hope thats helped (remember rated this) Good luck.

The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

For Low Beams: If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.

I have an 87 MR2 and this is how to adjust mine. Headlights have two spring loaded adjusting screws, one on the top controlling up and down movement and one on the side controlling left and right movement. The simplest method requires a blank wall 25 feet in front of the vehicle and a level floor. Position masking tape vertically on the wall in reference to the vehicle centerline and the centerlines of both headlights. NOTE: It may be easier to position the tape on the wall with the vehicle parked only a few inches away. Adjustment should be made with the vehicle sitting level. Starting with the low beam adjustment, position the high intensity zone so it is 2 inches below the horizontal line and 2 inches to the right of the headlight vertical line. Adjustment is made by turning the top adjusting screw clockwise to raise the beam and counterclockwise to lower the beam. The adjusting screw on the side should be used in the same manner to move the bean left or right. With the high beams on, the high intensity zone should be vertically centered with the exact center just below the horizontal line. NOTE: It may not be possible to position the headlight aim exactly for both high and low beams. If a compromise must be used, keep in mind that the low beams are the most used and have the greatest effect on driver safety. I typed this out of my "Haynes Manual 1985-1987 Toyota MR2 Book. I would think it would be the same method for a 1989 also. Hope this helps you. Redheadedwop
