Was just sitting down to dinner when the FJ Cruiser's horn started blowing constantly. Looked out the window and the marker lights were on. Had to unplug the horn fuse to make it be quiet, but lights are still on. Any idea what caused this? Only time it ran today was moving around the driveway, about 4 hrs ago. My guess is mice + wires,.
