My brake lights on my nissan sentra 2006, dont work, fuses are good and bulbs are good, how do I remove my brake light sensor behind the brake pedal?

Look to find how its fastened in place and what electrical connectors are hooked up to it and how they are fastened to the switch.disconnect the wire connector first noting how you removed it.then disconnect the switch from its mounting again noting how and what you did to remove it then re-install the new one in reverse order.this is all a tech does to do the same job.

It may not be the sensor, but a plastic button that presses against the sensor when you apply the brake. If the plastic button is missing, when you apply the brake it will not depress the trigger on the brake sensor.
