2002 BMW X5 Visibilitywiper Problems

CAR WAS PARKED. I TRIED TO UNLOCK MY CAR WITH THE KEY FOB AND NOTHING HAPPENED. I UNLOCKED THE DOOR WITH THE KEY AND AFTER GETTING IN THE CENTRAL LOCKING SYSTEM WOULD NOT WORK. AFTER RESEARCHING THE PROBLEM I FOUND THAT THE GMIII CONTROLS THE CENTRAL LOCKING AS WELL AS OTHER ITEMS LIKE THE WINDSHIELD WIPERS, INTERIOR LIGHTS, SUN ROOF, AND REAR UPPER AND LOWER HATCH. I ORDERS A NEW ONE AND WHEN I TOOK THE OLD ONE OUT TO REPLACE IT I FOUND THAT IT HAD CAUGHT ON FIRE AND BLEW FUSE 14. IT APPEARS A THYRISTOR OR TIAC GOT TO HOT AND SET THE BOARD AND CASE ON FIRE. I HAD SMELT A PLASTIC SMELL EARLIER WHILE DRIVING SO IT MAY HAVE BEEN BURNING BEFORE I PARKED. I AM ATTACHING PHOTOS.

THE DASHBOARD WENT DARK, ONLY GAUGE THAT WORKED WAS THE TACHOMETER WHICH I COULDNT SEE BECAUSE I HAD NO DASHBOARD LIGHTS. STOPPED VEHICLE AND TOOK THE KEYS OUT COULDNT TURN MY LIGHTS OFF HAD NO TURN SIGNALS,THE 3RD BRAKE LIGHT WAS ON ALL NIGHT LONG KILLING THE BATTERY I TRIED EVERY FUSE. ALSO MY HEADLIGHTS WOULDNT TURN OFF THE LIGHTING CONTROLS WERE USELESS, AND JUST KEPT SMELLING AN ELECTRONIC BURNING SMELL. I MANAGED TO DISCONNECT ALL THE LIGHTS EXCEPT THE 3RD BRAKE LIGHT. COULDNT DISCONNECT THE BATTERY BECAUSE THE LIFT GATE TO GET INTO THE BACK WOULDN'T WORK AND THE CENTER CONSOLE HAZARDS STUCK ON AND DOOR LOCKS DIDN'T WORK I HAD TO REMOVE THE GLOVE BOX AND ALL THE PANELING AND TRACK DOWN THE SMELL. TURNS OUT THE PROBLEM WITH THIS VEHICLE IS THAT THE RAIN MANAGES TO WORK ITSELF DOWN THE INSIDE OF THE A FRAME ON BOTH...
