If you have access to a power probe, use a power probe and see if your getting power to at lease going through the wires. Maybe your actually plugs are messed up.
Have you checked all the lights? Reverse lights, tail lights and brake lights?
Defective or out of adjustment brake light switch. Look somewhere on the upper part of the brake pedal for the switch.
Check the brake switch under your pedal (which needs to be pushed when the brake pedal is depressed). This is what the problem was on my friends Sentra. As long as you have checked the lights and fuses, this should do it.
If the bulb will not work the fuses under the dash should be checked. When these fuse fail the brake lights will not turn on.
Brake linings should be checked every 3,000 miles.
check brake fluid
Bad bulbs or brake light switch.
Brake lights and tail lights. (Unless you have a spotter telling you of course)
Could be the brake light switch or fuse.
Have you checked the bulbs themselves? The directional signal should be the same element as the brake light. Check to see if you rear directional signals.
Check the brake light switch it should be connected to the brake pedal somewhere.
I tried all the fuses, the parts that under the brakes I checked that. All lights come on and working except the brake lights no break lights.
