I had that problem when I had an F150 and also a Chevy 2500 several years back. I fought with them for months. In both instances, I ended up replacing the plugs with after market plugs I bought from etrailer and the problem went away.

Blew some compressed air through the 7 pin on the trailer but truck was not home at the time . Thought about some dielectric grease to lube all connections.Thanks for replies .
