It could be a Ground wire connection issue. Sometimes when a ground wire, that is hooked up to the engine, becomes unhooked it can cause some really crazy things to happen to the vehicle lights. Look up or ask one of the dealership's mechanics for the number of ground points that are to be hooked up on the engine and the remaining parts of the vehicle. If the amount of ground points start decreasing, because of corrosion or have fallen off, then it will put more of a demand on the remaining ground points, thus causing an overload and in some cases even an electrical short.
When you get bizarre electrical like that, the very first thing you check is for corrosion on the ground connections in that circuit. A corroded ground can't carry the added load when you turn on the signals.
