Turn signal getting wierd

[BBB]

Ok. I searched and found some answers but not my problem.
Rh turn signal. Cancels cruise,kicks of tcc and when pulling trailer drags my electric brakes. Disconnect trailer and the trailer plug on truck. Same problem. Checked and replaced bulbs all working front and back,
Replaced the multi function switch. No cure??
Ive looked at some wiring.
Only rh turn does it and softly lights trailer led on Lh side. Not on truck

Not the trailer not the 7 pin socket. Im stumped. Any help. Thanks

I figured out the problem. When i replaced my tail light bulb i decided to use a LED replacement. It does not work. Causes the problem. Put old 1157 in and good to go. Led worked good. Just caused the problem

Yeah the way these were wired from the factory LEDs cause funky issues. I'm glad you figured it out.
