I would say no. But the brake lamps do work in conjunction with the turn signal and hazard switch assembly, but I really doubt that is your problem because the voltage goes from the brake lamp switch first, then into the hazard flasher switch. There it is divided by the switch and routed to the correct lamp assembly for turn signals and stop lamps. Your first test after checking all fuses, should be to see if there is power going into the stop lamp switch. As I said before a dead or real low battery could also cause this kind of problem. Let me know how you progress, I will be here. Thanks, Bob
