    Start unplugging switches one at a time until problem stops. That is your bad switch, Bring switch with you to Freightliner so they can match. Some are open, some are closed.

    Clean out your trailer plugs, have seen when the truck side plug is corroded/fouled causing power to short over to other pins. The trailer plug on the truck side hardly ever gets cleaned and lubed.
