No, it was doing the same thing, sometime it worked sometime it didn't .At that time I thought that it was just the turn signal and only figured it out today that it was only out when I had the lights on and that the tail light didn't work.
My 2007 grand Cherokee has been having a problem with the rear driver side turn signal and the tail light on that side, they will not work while the head lights are on, any suggestions? I just changed the bulb when the brake light went out.
