FYI well i have not had the headlight problem yet but with the frequency i read about this just for curiosities sake i decided to call a local dealer.
$1200 for both lights, since they do not replace just the gears, but they replace the motors as well whether you need them or not. i do not have a shop so i will probably have to call someone who can do just the gear job.
. if anyone knows of someone i would be interested.
