I LEFT MY TOP OFF OF MY JEEP WRANGLER AND IT RAINED HARD INTO THE NIGHT AND NEXT MORNING. I HEARD THE HORN GOING OFF RANDOMLY SO I RAN OUTSIDE AND THE DRIVERS SIDE DASH AND STEERING COLUMN WERE ENGULFED IN FLAMES. I QUICKLY OPENED THE HOOD, DISCONNECTED THE BATTERY AND THEN PUT OUT THE FIRE WITH THE HOSE. THE WHOLE STEERING COLUMN AND SURROUNDING DASH AND WIRING HARNESS ARE COMPLETELY MELTED. THE INCIDENT HAPPENED WHILE THE JEEP WAS PARKED IN THE DRIVEWAY
