Need some electrical help I’m clueless

Little bit of background, pulled the steering column in one piece to replace the coupler. Now all that’s done and it’s put back in no problems. I was checking all the instrumentation and headlights and turn signals, and everything works correctly except the turn signals. The left side will blink only the rear tail light, the front doesn’t work. The right side the back tail light will blink and it’ll suddenly go rapidly blinking and sounds like there’s a cricket going crazy under my dash somewhere. I’ve checked the little turnsignal flashers and swap them back and forth and no change. I have no idea why the turn signals are doing this. None working up front and one side good at the back and the other side going crazy. Any thoughts?
