every now and then (and lately a little bit more often), it seems like the headlights aren't always properly leveling. i will see them raise up and down when i turn them on like normal, but a lot more often they'll settle into a lower position and not really light up the road in front on me. it was really bad driving home last night. i see them moving side to side on turns. is there a way to force it to re-level? or am i headed towards replacing the AFS control module as mentioned in previous posts?
