01 sport, 5 speed 3.9 V6. Step on the brakes and no lights. Signals, flashers, tail, reverse, and cargo lights all work. Brand new bulb in third brake light. Just replaced the brake pedal switch. All fuses look good. Unless there is one I do t know about. Removed the trailer lights hook up. I traced the wires from the rear to the firewall and didn't find any sign of damage. Is there something I missed, what should I recheck if not all?
