Turn Signal Issues?? Right one works and left one doesn't

First off, Hello!!!

Driving a 2001 Kenworth T800 with a C15 6NZ.

Turn signals were working just fine until yesterday or at least today for sure. Yesterday, another driver said that my right side light was on but not flashing so the moved the turn signal switch and it went off. Today I was moving some equipment and I noticed that I did not have a left turn signal but the right side was working. The hazards were working but I think the left turn would not light up. Then neither side would work but most of the time the right side would flash and not the left. Mess with the lever and it was like the left would try and quit.

Finally was able to spend two hours on it before moving another load and I'm stumped. Took the switch out, put another one in it(not the right one due to it fitting a 99 but the connector was the same) and there was no change. Changed out flashers and that didn't do anything. Looked for a fuse or secondary relay and there was nothing. I pulled the extra kick panel to the left of the fuse panel and it seemed like whatever I moved, maybe caused it to start working.

Left to go move my load and it worked good other than one time, get to where I unloaded and the left turn signal quit working again. Moved the lever back and forth and then right one quit so I had no turn signals but the hazards worked.

When it was time to go, went 1/4 mile and everything seemed to be working again. Just trying to figure out what or where I need to check to figure this out. When the right side would work, you'd see the relay working correctly, but when the left side would not flash, you could see the relay try to move and then act as if it was stuck?

I unplugged the trailer, unplugged the rear led lights and the front led fender lights which did not make a difference. The only thing I did not unplug was the light bar on top and it is led also so I doubt that is the issue. When it works, it works great but you never know when they are not going to work.

Don't know what else to try. Got the correct signal switch coming tomorrow but I don't think that is the problem? Any ideas on what to do?
