Aims up cant turn screw any more - Crown Headlight Adjust Screw Jeep Grand Cherokee 96 95 94 93 Car 56006405

1. Park your car on a level surface, facing a flat wall or garage door. Make sure the car is at a normal operating temperature and that the headlights are turned on.
2. Open the hood and locate the headlamp adjustment screws. These are usually located at the back of the headlamp assembly, near the firewall. There should be one screw that adjusts the vertical aim and another that adjusts the horizontal aim.
3. Use a Phillips head screwdriver to adjust the screws. Turning the vertical screw clockwise will lower the beam, while turning it counterclockwise will raise the beam. Turning the horizontal screw clockwise will move the beam to the right, while turning it counterclockwise will move the beam to the left.
4. Adjust the headlamps one at a time. Cover one of the headlamps with a thick cloth or cardboard to prevent any stray light from affecting your vision while you adjust the other headlamp.
5. Aim the headlamps so that the center of the beam is at the same height as the center of the headlamp lens. The horizontal aim should be straight ahead, with no visible lean to either side.
6. Test the headlamps on a dark road to make sure they are properly aimed. If you notice any unevenness or misalignment, make further adjustments as necessary.
7. Close the hood and enjoy your properly adjusted headlamps.

It's important to note that if you're not comfortable working with car electronics, or if you're unsure about any of the steps involved in adjusting your headlamps, it's best to consult a professional mechanic or authorized Jaguar dealership for assistance.

Owner's manual says high beams will be adjusted by correctly adjusting the low beam.

AIM,
is it a usa CAR, other countries have auto aim lights, i cant guess this.
this is all in the fsm, if you wish to read it. (USA FSM dig:?)

http://www.helminc.com/helm/search_service_owner.asp?Style=helm&class_2=TOY

some head lights to day (trend ) are fixed left and right and only
go up and down. (prevent , ("shade-trees") from blinding oncoming drivers.
first is to test the aim!
if off vertically the fsm shows you the screw to adjust.
what I do , is just LOOK at it. its obvious what is there and not.

if doing DIY work why not get the book?
photos and steps all there, clear as day.

I hope this info helps!

For installation, follow removal procedures in reverse order. Make sure to check headlamp aim.

two screws on each headlight control the direction the headlights are aimed. One screw, usually at the top but sometimes below the headlight, adjusts the headlight up and down. The other screw, located to one side, controls the headlight from right to left. Turning the appropriate screw one direction or the other will change the direction the headlight points.
In order to aim your headlights you need to have a flat vertical surface you can aim your headlights at in front of a level surface on which to park the car. If your driveway is level your garage door is the perfect place to aim your headlights.
The tools you will need for this job are simple. Masking tape is used to mark where the headlights are to be aimed and a screwdriver is needed to adjust the headlights. A tape measure will be necessary to measure the distance of the vehicle to the surface you're using to check the aim and to measure the up and down distances from your marks

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.
