I fixed my rear adjuster ... I had to raise the headlights a number of turns back to what I suppose is close to the original factory position. I remember lowering the headlights quite a bit when I first installed my springs so this makes perfect sense. I also opened the trunk and pushed down on the rear to see if the headlights adjusted and they seemed to. Thanks for the great info.
I believe many of us are driving around with our self-adjusting headlights crippled based on re-installation error. Nice to have this functioning again as it was intended.
