So my 2024 trial boss has an interesting issue, no running lights or reverse light in the back on the driver side but the brake and turn signal work fine. Changed all 3 bulbs and checked the pertinent fuses and everything looks good but new bulbs didn’t resolve the issue. Anyone with experience with this? Scheduled service but would love to solve this on my own before I have to bring it in. Got a multimeter gonna go out and check all the fuses if I have to.
Thanks!
