2001 Ford Focus - High beam / low beam problem with headlights
Got a problem with the headlights on my 2001 Ford Focus ZX5. About a month ago I'm driving to work with my brights on, there's an oncoming vehicle so I switch back to low beam and the headlights go off. The running lights are still working. I switched back to high beam and they came on. I turn back to low and they go off. I turned the knob for the lights off then back on, and the low beam came on again. This problem was consistent for about two weeks. As long as I didn't turn on the high beam, no problem.
Then I'm going to work and about a mile away my lights just shut off, they were on low. I turned off the knob and turned it back on and they still didn't work (this worked two weeks ago). Then I turned to high beams and they worked. I checked that afternoon when I left and it was still in the same condition; only the high beam worked.
Next morning, I get in the car figuring I'm going to have to drive all the way to work with my high beams the whole way and to my surprise, I turn on my head lights and they worked on low beam; didn't push my luck and try the high beam. Drove to work, and about a mile away the low beam goes out again. Turn knob off and on again, still only running lights, turn it to high beam and they work. Same status that afternoon, only high beam.
I took it home, checked fuses, all OK.
Swapped the high beam/low beam relays, still operated the same, on high beam only.
I drove like a bat out of he** to work the next day and made it the whole way on low beams (about 20 minutes). Sat in the parking lot and turned on the high beam and it wouldn't cycle back to low beam every time I pulled the stick back. It got stuck a few times on high. That afternoon, only the high beams worked, no low.
I took it home and removed the high/low and turn signal assembly, went to the store, out of stock, ordered it on two day delivery and put the old assembly back in. Drove it the next morning and the low beams came on, highs would get stuck.
I was checking this stuff so often that I started to check it when the car wasn't running. When the keys weren't in it, low beams wouldn't work (running lights still on), and the high would. When I'd start the car, low beams would work. I replaced the high/low turn signal assembly when it came in, but it didn't fix the low beams completely.
I haven't driven it long enough to see if the lights shut off while driving, but this is where it stands. I turn the car on, the low beams work. I turn off the car, only the running lights remain on. High beams work with car running or not. I aso pulled both headlights to inspect the wires and nothing looked corroded or worn. I put some dielectric grease on the connections and put them back. Sorry this was so long-winded, but wanted to give a complete history. Any ideas?

There is a conflict with your vehicle and the listing you made for the type of vehicle. But several things to point out. First, if you drive on the opposite side of the road in France versus the United States, the headlight aim would be reversed.
The aim of the headlights can be different in the United States depending on State rules. In general, the curbside light is adjusted higher and the light on the oncoming traffic side is lower. The traffic side is adjusted more towards the center of the vehicle and the curbside is slightly over the curb. You do not want a dark area in the middle of your travel direction.
The vehicle is between 25 and 30 feet from a flat surface The light is adjusted a certain height from the ground. These specs vary and the height of your lights can come into play. Cover the opposite headlight to isolate the beam from the one you are adjusting. A simple towel can cover a lens.
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
