i posted this a few weeks back but did not get enough response and i still have the problem, so i am going to try again...
i was adjusting the vertical focus of the headlights using the knob right above the headlight back cover. The knob would turn to adjust the beam down but it would not turn back up. The passenger side headlight is now too low that i have to use the high beam all the time. i am now tempted to disassemble the headlight assembly to see what is wrong.
any suggestions? if i need to disassemle the headlight, is there a handy procedure to follow?
