If the white screw is turning, it should be moving the light. Unless the little gear is stripped out or something else is wrong. You can try taking the light out and check the housing of it while you turn the screw. Youll need to remove the grill and I think 3 or 4 screws for each light then unplug the harness.I had my factory LED installed by the dealer a few weeks ago. I've been getting flashed by oncoming vehicles as though I had my high beams on. I did the 25'/3' test and sure enough I'm about 4' on the wall.
I tried to adjust using the white screw wheel but nothing happens the beam won't go up or down. Same result when I tried adjusting both lights.
I'm very certain I have the screwdriver in correctly as I can see the white wheel turning also.
Am I not doing something correctly ? Solutions?
