2017 Hideout no bake or signal lights

[Alan_Wilson]

All of our lights light up but no bake lights or turn signals come on. Last trip was in July and everything worked fine. Was supposed to leave for Florida tomorrow for Xmas. Any help would be great.

Ck fuses on the TV!

On my 2015 Ford SuperDuty, the fuse panel under the hood has multiple fuses that protect the truck wiring to the trailer umbilical....

I'd first check the truck umbilical connector to determine if the problem is "with the truck" or "with the trailer".... If there's power on the turn signal pins in the truck umbilical connector, then the truck is OK and the problem is with the trailer. If there's no power at pins then troubleshoot the truck fusebox/wiring...

If the truck checks good, then I'd focus on the trailer umbilical connection block, which is probably a 4x4 metal junction box, mounted on your trailer tongue or the front bulkhead. It likely has 7 or 8 twist on connectors holding a "spaghetti like" wiring harness interface. After 6 or 7 years, those tend to corrode or loosen and can cause problems. Another possibility is a bad ground on the trailer brake/turn signal wiring. Usually that happens at or near the actual tail/brake light fixtures. They sometimes use a single ground wire for both left and right lights and that wire corrodes and causes problems.
