Hello. My name is ***** ***** I will be assisting you today. I see that you brake lights are not functioning. Just so that I am clear, is it just the brake lights, or is it all the lights in the rear that are not functioning?

I see that you have replaced everything including the fuses. The next step would be testing the wiring. Have you checked to see if the module was getting power and ground?
