MY 2011 MERCURY GRAND MARQUIS ULTIMATE EDITION, WAS VERY GREAT HOWEVER IT CAUGHT ON FIRE DUE TO THE MALFUNCTION OF THE WINDSHIELD WIPERS...THEY WOULD COME ON AUTOMATICALLY WHILE I WAS DRIVING, MY WINDSHIELD WIPER SWITCH WOULD BE ON THE OFF POSITION... AND THE WIPERS ONLY WORKED ON A HIGH SPEED SEEING NONE OF THE OTHER SPEEDS WORKED...PRIME EXAMPLE I WOULD WARM UP THE CAR FOR 10 MIN...BECAUSE ITS COLD OUTSIDE THEN I WOULD DRIVE, ALL OF A SUDDEN MINUTES LATER, MY WINDSHIELD WIPER TURN ON BY ITSELF IN A HIGH SPEED POSITION , I TURNED THE WIPERS ON SO I CAN SEE IF TURNING OFF WOULD HELP IT DOESN'T SO CLEARLY IT HAS A MIND OF ITS OWN...AS IF A GHOST WAS IN IT...I GOOGLED THE PROBLEM..CLEARY THERE ARE OTHER MODELS OF THE SAME AND DIFFERENT YEAR NUMBERS THAT HAVE THE SAME PROBLEM...THEY SAY ITS EITHER THE WIPERS MOTOR A RELAY OR THE WHOLE LEFT, RIGHT INDICATED SWITCH WHICH THE WINDSHIELD WIPERS WORKS OFF OF...LONG STORY SHORT MY CAR CAUGHT ON FIRE THE MORNING OF NOV.21, 2018 A DAY BEFORE THANKSGIVING IN MY DRIVEWAY WHICH COULD HAVE SET MY CAR ON FIRE..HAD TO CALL THE FIRE DEPARTMENT AT 1:45AM IN THE MORNING. DUE TO AN ELECTRICAL ISSUE THE CAR HAD..IT LOOKED LIKE A MOVIE WITH THE CAR ON FIRE. BECAUSE CLEARLY IF THE CAR IS PARKED AND THE WINDSHIELD WIPERS MOTOR IS STILL TRYING TO MOVE WITH NO POWER TO THE CAR...I LOVED THAT CAR SO MUCH..IT ALMOST CAUGHT MY HOUSE ON FIRE...COULD HAVE EXPLODED AND PUT MY FAMILY AT RISK.WHICH IT DID. AS MUCH AS I LOVE FORD, LINCOLN, MERCURY I AM JUST SAD
