Typically when this happens the issue is that the connection made on the problem side just wasn't made all the way. If you unplug and replug in the connection on that side that usually cleans up the issue.

You might also make sure that the pins of the trailer connector are clean as well. If you see corrosion take some sandpaper to the pins of the connector.
