Trailer light issue
22 350
Having some issues with trailer lights on multiple trailers that didn’t give me trouble on my old truck 2 weeks ago
At any rate
I’m getting a trailer light module fault on dash
also right turn signal not working but when I hit the breaks it goes away then pops back up as soon as I use the turn signal
so what I have troubleshooted so far is that the right side turn signal works intermittently
no left turn signal at all
when I tested 7 pin on truck with multi meter I’m only getting 5.6 volts off left side and 6.8 on right side. Maybe that’s why right side led turn signal works intermittently
obviously I have warranty and that’s what my route will be eventually but I am headed on a 1000 mile snowmobile trip this weekend and I’m sure the dealer won’t be able to get me in before then
any in-site to the possible issue would be great
thanks

Had the exact same problems that you're having plus intermittent brakes not working with the screen showing that fault and trailer disconnected long after the trailer has been disconnected. All my trailers worked with my 2018 and with the 2022 all these things have been happening. Replaced the trailer socket on the truck with an aftermarket one. That solved my problem on the 2018 a couple of years ago and it solved the problem on the 2022. Takes 2 minutes to replace it. Wasn't worth my time or effort to take it back to the dealer.

Had this issue on a 16 f150, unhooked the back side of the 7 pin, sprayed both sides with wd40, hooked it back up and it worked fine

I haven't worried too much about it because the turn signal works, even if it takes a flash or two to start.
