Ok Timmahh, this was a $1500 saver for me! I crunched a pothole at the end of December and the next thing I know, my drivers side light is pointed to the sky and would not level. AHL still worked fine but vertical leveling was a no go. The local dealer looked at it, "tested it" and said the motor was bad and wanted $1500 to fix it. Despite NO EROR CODES, the dealer said it tested bad....
I pulled the bumper off, pulled the light out, and had it fixed and back together in an hour thanks to this write up. This definitely needs to be a DIY!!!!
