MY BRAKE LIGHTS JUST DECIDED TO QUIT WORKING. I HAVE REPLACED THE BULBS, FUSES, REAR WIRING BRAKE HARNESS AND THE BRAKE SWITCH AND THEY STILL WON'T WORK. WHAT ELSE COULD IT BE? THEY CAME ON WHEN FIRST REPLACED EVERYTHING AND THEN ONLY 1 SIDE WORKED AND NOW NOTHING. EVERYTHING HAS BEEN REPLACED WHAT ELSE COULD IT BE?

Hello, does the highmount brake lite work? The highmount is wired differently than the lower brake lites, the lower brake lites are wired through the turn signal switch. At the malfunctioning brake lite, did you check for B+ and ground?

NO THE HIGH MOUNT BRAKE LIGHT DOES NOT WORK EITHER. ONE SIDE WORKS IF YOU USE THE TURN SIGNALS AND THEN FOR NO REASON THEY DON'T WORK. CHANGED BRAKE LIGHT SWITCH AND REAR WIRE HARNESS INCLUDING ALL TAIL LIGHTS. EVERYTHING WORKS BUT BRAKE LIGHTS AND HIGH MOUNT BRAKE LIGHT. ARGGGG

Did you check the voltage circuits at the brake switch? The orange wire is feed to the switch, hot all the time. The white wire goes hot when the switch is activated, the white wire carries the feed for all the brake lites.
