Question about 2001 Nissan Xterra
I replaced the fuse and the bulbs for the brake lights but they will not work? What can I do next?
You need to replace your brake light switch. It is located on the brake pedal under the dash. Good luck

Yes, you need to of course check the voltage coming into and going out of the brake light switch, if 12 Volts are there going out and coming in while pressing on the brake pedal, your brake lights aren't getting a good ground or there is a break in the circuit between that switch & the lights.
On occasion the tail lights will work with a weak ground circuit where the Brake lights won't. Best way to determine this is to just hook up the 12 volt tester to the Brake light hot wire & there at the bulb ground, then in an area away from the bulb that has a good possibility of contact/ground.
Really that's it, if the 12Volts is getting to the bulb but it isn't lighting, if you aren't getting the voltage there and the brake switch is hot on both sides when pressed, the break in voltage will have to be traced from that switch to the tail light to find the problem.

There is a flaw in the wiring of this model to the rear brake lights. Take it to a trusted mechanic if they follow the wires they will see where the sodder/connection has been broken. Jeep no longer uses this type of wiring. My mechanic said he got lucky and found the break, but if it happened again, he would have to replace ALL the wiring most likely.
FYI - I had this same problem about a year ago.

It could be the relay, which is a yellow box located under the carpeting in the trunk on the left side. It is a problem common to your model. Also, check the brake switch's (behind the brake pedal) functionality (12V present with key at ACC or ON and continuity between wires when button engaged).
i hope this helps

Testimonial: "Wow! I would have never found the problem without you guys. It was the relay located in the trunk. Thanks!"
