I want to adjust the headlights on my '04 (same as '02s and '03s, by the way), but no more 'bubbles' on them anymore Seems a lot quicker and easier to adjust the 'arm' on the auto-adjusting rheostat on the left rear wishbone, to fool it the car was raised, so the aim will be proportionately higher on both headlights at the same time. I plan to mark the factory position just in case.
My question is how does the factory set the 'default' position, and is that stored on the ECM? Can the leveling motors be 'zeroed' in, or reset? What happens when the battery is disconnected, which I did when new? It only makes sense that the 'arm' is permanently adjusted, with the info stored in the ECM, so me thinks raising the arm should work as an adjustment.
My last question is where are the leveling motors: outside or inside the headlight cluster.

Please don't suggest the dealer. I want to adjust them myself either the conventional way or the 'arm'.

Thanks in advance for any tips.

Nobody with a service manual, even on an '02 or '03? Strange.

I'll wait until I can buy the '04 version then.
