Stop Lights Voyaguer 2001 do not turn on.

I have a 2001 Voyaguer, when you step on the brake pedal do not turn on stops. I have reviewed the spotlights and the filaments are fine; The platinums of the brake pedal sensor still work well. I have checked the fuse in the box that is next to the battery and is well.
Someone who has had this problem and can give me the solution or can advise me in which part more to review.
Thank you in advance.

Do you checked enough elements for what I see, but you checked that current arrived to the bulb? There is a car that the brake lights work with the ignition in ON.
