Ok ive tried everything and get nowhere. Its all started when the plug on my trailer went bad. Got that fixed and my blinkers were working then occasionally they wouldnt. But now i have no blinkers at all. Ive replaced the switch twice and all the fuses. Nothing seems to be blowing fuses. Ive switched relays around to see if it would come back but nothing. Ive even unplugged my trailer hookup on my truck to see if that was bad and nothing. And whats throwing me off is i have no blinkers hazards and no brake lights. I dont know what else it could be. If anyone could help id appreciate it. Thanks.
Did you look all the way up under the bed at the connectors for
the wiring. Take the tier down and check the point where the
main harness is split to the right, left and trailer. Then trace
it back up the frame to the cab.
You will likely find some damage or a burned contact in the connections.
Be sure to use some dielectric compound when you reassemble
all the connections.
Are you working on the front and rear signals or just the rears or just the trailers signals?
What switch and what relays have you messed with?
Try to be concise and descriptive. Try using the same terminology used in the owner's manual instead of slang or other such terms since they may not be explicit.

Not trying to be an a-hole, but a good rule of thumb is that when something goes wrong, go back to the last thing that was changed and start troubleshooting from there.
