Have a brake light issue on 2003 Volkswagen Beetle

Nether of the brake lights work but the Center bar does work. But both running lights work just fine. Checked both of the Bulbs and they were both fine. Checked Fuses in the Fuse Control Panel and they were fine too. I also Checked the Brake Control switch and that was good. What could be the problem??

Check harness for broken wires , check all connectors in circuit for good contact.
