I recently bought a 2007 ford edge with the 3.5L. It had a tail light out but I didn't think anything of it. Went to change the bulb and realized it was still good. checked the fuses and all were good. Come to find out the center wire for the brake light and turn signal was not getting power. the running lights work but the turn signals and brake light for the left rear corner does not. The dash indicator for the turn signal lights up and flashes fast when turning left. The front blinkers both work on both sides. I checked continuity from the light socket to the cabin fuse box and it runs true all the way. I gave the wire 12 volts and the light illuminates then. Are the cabin fuse boxes known to go out every once in a while? Not sure what else it would be. I also have continuity between the blinker switch left into the cabin fuse box as well.
