Turn Signal issue

[sidekick41]

Good day all,

We just noticed that when we hit the left turn signal, both the rear left and right turns signal are activated. Just the rear, the front works as designed. When you hit the emergency flashers all is good as well.

We have a 2015 Thor Challenger 37LX and the stock radio has been replaced and all the cameras have been moved to a separate monitor.

I plan on tackling the troubleshooting this weekend. I was looking for a post, I saw last year, which lays out the components but can't seem to find it. I'm assuming the turn signal siring goes into something that would tell which camera to turn on which I suspect might be the problem but any ideas or knowledge would be greatly appreciated.

Peace Out!!

Could be as simple as a shorted socket. The taillights assembly on many of the Thor MH's leak.

If that is on a freightliner chassis, they use relays as turn signal flashers, 1 for right side and 1 for left side, I would pull those out and look in the sockets for any green corrosion, that chassis fuse box was notorious for not sealing very well.

Thor Challenger is on a Ford F53 chassis.
