Combo light switch going bad

[Sonyps307]

All lights work including front markers, headlights, fog lights, all gauges, turn signals, and brake lights when brake pedal is pressed. Only lights that don't work r the tails, rear markers and License plate lights. I did the Failure module bypass by jumping the wires and still only brake light work no tails still. I think it's the combo switch ill test it tomarrow. Thanks
