Wiring Problem - need help

Right turn signal blinks rapidly when turned on. Right front signal working but flashing rapidly, rear right signal not working. Right rear brake light does not work. Park lights and 4 ways all work. Backup lights and license plate lights work. Left side works fine.

Checked the bulb and replaced with a new one, still have same problem. Thought the problem was corrosion due to trailer plug cover being broken off and letting in moisture. Replaced trailer receptacle and still have problem.

As I mentioned, 4 ways work all around the truck, even the bulb on the right rear that doesn't work but is the same for the turn signal and brake.

Well looking at the wiring diagrams the only place something like this could happen is in the multifunction switch.
