All of the brake lights are out on my 2005 xterra. The tail lights still work, the reverse lights work, bulbs are good. I checked the brake light switch on the pedal and it is good, all fuses are good and plugs are all connected. I am not sure what the problem could be now. The auto parts store said that my vehicle doesn't have a brake relay and I cannot see that it has one so I am at a loss. Please help!

sounds like a bad ground or a break in the wire harness

Have you checked for a burned out fuse? Tail lights also (typically) have two filaments. One for parking lights and another for when the brake switch near/on the brake pedal is in the on position. This switch is another possible source of your lack of illumination. Reverse lights should/might be on a different bulb. If you have already verified that the bulbs and fuses are good, try changing/adjusting the physical switch at the brake pedal.

The brake lights and reverse lights are on different circuits with different triggers. Check any trailer connections you have connected or spliced in that could be leading to a short. Double check the light control switch. If you have no tail lights when the lights are on then the problem is most likely the light control switch.
