It sounds like you have a short in the electrical system. They can be hard to find, but I would first focus on the wires under the dash, where you saw the smoke. It is possible that the melted and shorted wires are within the wiring harness and may be very hard to see without removing the protective covering on the harness. I suggest having a certified technician, like one from YourMechanic, perform electrical testing to determine the exact cause of your concern or short, and go from there.
