So I recently discovered that on my 2006 V6 Mustang, my rear driver side taillights arn't working. When I turn my headlights on the taillight lights up, but when I turn on my left turning signal the rear taillight does not do the sequential lighting. Also, when I turn my hazards on or press the brake nothing works on that side either. Now the front-driver side turning signal works but not the rear. The rear passenger side taillight operates completely fine. I just purchased a new Duralast...
