It's just the one side (right). I was always under the impression that power for the trailer's brakes comes from the trailer battery and only engages when the breakaway switch is pulled.
If it makes a difference, I just switched vehicles -now driving a 2013 Nissan Frontier.
Has anyone ever had this sort of situation before?
When braking your TV power is also sent to the TT brakes if you have a brake controller installed in your TV. The brake away switch on the trailer works off your TT battery and applies the TT brakes in the event of a brake away. You definitely need to get your wiring checked, another possibility is if you have a brake controller and it isn't adjusted correctly it can lock up your TT brakes.
