I experience intermittent loss of right turn signal on my 2012 Arctic Fox 25Y trailer. The error message shows up on my 2016 Ford F-350 dashboard. I used to think it was only in the rain, but now it happens sometimes ANYTIME. It comes and goes at will. I have one of those trailer connection testers but it shows the system on the truck is fine. This problem never occurs when not towing. Only when we're towing. When I talked to a service guy at Ford he says bring the trailer in with the truck. We can't do that. When the error code about the right turn signal not working comes up, it does the customary fast blink on the dash, but it may or may not show up on the turn signal in the trailer. Huh? And of course, nobody can fix anything unless it's not working at the time they look at it - which it never happens. We can be sitting still and it will all of a sudden give the code, so vibration doesn't seem to be it. I've sprayed the connection wire and the plug with electric cleaner spray with no effect. I've pulled over in a rain storm and jiggled the plug to no avail. I think it's definitely the trailer. I have another trailer I sometimes pull with NO problems.
Tommy, did you ever get this solved? There are two right-turn bulbs, the one on the truck and the one on the trailer, do they both fail? Are any of these bulbs LEDs? If the truck uses something like a CAN bus it may "think" there's not enough current draw, intermittently.
No I haven't, but I haven't been out with the trailer in quite some time. It's definitely in the trailer because if I unplug the trailer while this is going on, the truck light blinks as it is supposed to. I've swapped out the trailer taillight - to no avail. It's a 'perplexment' . . .
