Thanks. I forgot to mention I do have 11.5 on the working left side and about 1 volt less on the non working side off the bed connector (no trailer). The three trailers that have the same issue using the same truck have their own cables. I will check the other fuses and report back. Thanks again!
Have a Chevy 2020 2500HD where the Trailer Right Turn/Brake light is not working. Lights on the truck itself ok. I found related fuse 81 blown and replaced it - no help. TIM fuse 82 is ok. Problem is present on 3 different trailers. Any help is mostly appreciated.
Thanks!
