Rear Right Turn Indicator Light Not Working

[TheDanimal]

I have 2015 Fleetwood Bounder, and suddenly the right turn indicator on the back of the chassis is not working. I have checked what I think are the 'usual suspects', fuses and bulbs, and those do not appear to be the issues. Bulbs are both good and work, fuses were swapped and still same behavior. The front and side indicator lights still work, but it is just the back that stopped.

Does anyone know if the wiring has fuse in a wiring harness somewhere? I looked up under the chassis and took apart one of the wiring connectors but didn't see a fuse. Maybe I am missing one?

Any other ideas or thoughts?

Thanks in advance!

What chassis is it? If this was a Freightliner, I would be checking the grounds, and the splices where the factory spliced into the Body interface connector.

And look closely at the fuse labels inside the fuse box. And No there are no inline fuses.

I would take the bulb out and use a voltmeter to see if the signal is getting back there. For the ground probe, use the intended ground wire first, and if no signal go directly to ground with the (-) probe. If you can't get a signal on either of these points, start working your way forward until you can pinpoint where the problem is originating from.
