Looking at the wiring diagram it looks like they share a fuse and a relay. I would start with a simple test lamp and with the lights on check for power at both ends of the Tail light fuse in the junction box at the left side of the dash. If there is no power to the fuse, then it is likely the relay. Replace it and see if the lights return.
