My truck (2019 F250 Lariat) started notifying me constantly that a trailer was connected and then 5 seconds later that it's been disconnected. While driving down the road. Without a trailer. And it does this constantly.
I had a mechanic change out the 7-way plug all the way back through the connector. Worked fine for 1 day and then back to the problem.
He said moisture in the 7-way connector. But I have a new one in and same problem. And I have 105,000 miles on it and never had a problem before. And when I hook up a trailer, the problem goes away.
Looking for any insight and help on this. Also calling other diesel mechanics in Dallas.
