2002 Chevrolet Cavalier Rear brake lights not working

The brake lights and signal flashers all run off the same fuse, so if the signals are working, we know the fuse is okay. The most likely cause of this problem is the turn signal switch, however, the center high-mount brake light should still work. That one doesn't go through the signal switch. Check the two bulbs in the center brake light to see if they're burned out. If they're okay, there is a break in the wire before or after the brake light switch.
