I’m pretty new to group.
I have 77 Power Wagon brush rig fire truck plus 2017 Ram

My question currently is issues with my 2017 Ram 3500 4x4 diesel
My left taillight is out.
I put new bulb in and it’s still not working.
Fuse is ok
Also noticed that I sometimes can’t change channels in my satellite radio
Additionally when I turned off engine waiting for road construction when I restarted engine message that tow haul mode was active came in. In the past when motor shut off I would need to turn back on tow haul & exhaust brake modes if I wanted them.
Additionally clearance lights on my camper stopped working too.

truck has about 90K on it now.
Had it since new and meticulously maintained it.

Any suggestions to help figure this out would be appreciated.
