Directionals not working properly

The truck I have is a 2016 f550 with a curry service body on it. The problem I'm having is the brake light and directional on the right side of my light bar and rear light are not working. Here's the catch...when I turn the directional to make a right turn ,the left directionals on the light bar and rear taillight go on but the right directional on the front marker work correctly. I've also checked my trailer plug ang that is working correctly. I've checked all the wiring under the truck and can't find anything pinched,corroded or shorted. Is it possible my body control module is bad or am I missing something else. Thanks Richie

Sounds to me like you have a bad ground, a lot of service body lights are mounted in rubber and have a dedicated ground running to them from the frame.
