2004 MERCURY GRAND MARQUIS Complaints

WHEN DRIVING AT NIGHT THE LOW BEAM HEADLIGHTS GO OUT WHILE VEHICLE IS IN MOTION. THIS FAILURE IS UNPREDICTABLE AND LEAVES THE DRIVER LITERALLY "IN THE DARK" WITH THE VEHICLE MOVING AT WHATEVER SPEED AND DIRECTION IT IS GOING AT. THIS IS DEFINITELY A SERIOUS SAFETY ISSUE AS MY RESEARCH HAS FOUND THAT THIS IS A COMMON FAILURE OF THE VEHICLE'S "LIGHT CONTROL MODULE" (LCM). FURTHER RESEARCH REVEALS THAT THE FORD / MERCURY AUTOMOTIVE DEALERSHIPS MAINTAIN A READY STOCK OF THIS PART FOR REPLACEMENT AT THE HEFTY AVERAGE PRICE OF $ 700.00. GIVEN THE SEVERITY OF THIS SAFETY ISSUE IT IS DIFFICULT TO UNDERSTAND WHY THERE HAS BEEN NO APPARENT ACTION BY NHTSA TO REQUIRE A RECALL BY THE MANUFACTURER. THIS FAILURE RECURS FREQUENTLY AND UNPREDICTABLY. *TR

VEHICLE HAS DEFECTIVE LIGHTING CONTROL MODULE (LCM). HEADLIGHTS WOULD NOT TURN ON UNTIL LCM WAS KICKED. (LCM IS MOUNTED DIRECTLY ABOVE GAS PEDAL) NOW HEADLIGHTS ARE TURNING OFF WHILE DRIVING. (BUT COME BACK ON IF THE LCM IS KICKED. ) LOOKING AT EBAY THERE ARE MANY COMPANIES THAT OFFER A TOTAL UPGRADE OF YOUR EXISTING LCM. THEY INSTALL HEAVIER DUTY RELAYS. THE PART # ON MY LCM IS 4W7T-13C788-AA. SO IT IS EVIDENT THAT THERE IS A PROBLEM WITH MANY LCM'S IN AND AROUND THAT MODEL YEAR.

THE NIGHTTIME HEAD LIGHTS FAILED ON THE MERCURY MARQUIS. 2004 MODEL; WE BROUGHT THE CAR INTO THE DEALERSHIP TO HAVE THE MODULE REPLACED WHICH IS EXPENSIVE. *TR

MY 2004 MERCURY GRAND MARQUIS HEADLIGHTS KEEP TURNING OFF WITHOUT WARNING AT NIGHT. I ALMOST KILLED A PEDESTRIAN AS THE LIGHTS WENT OUT AT NIGHT AND I COULDN'T SEE BEFORE STOPPING THE CAR. I DID HOWEVER STRIKE THE EMPTY BABYSTROLLER THEY WERE PUSHING WHICH CONTAINED GROCERIES. I'M TOLD BY THE DEALER THAT IT IS A MODULE. COSTING $500. PLUS $99 AN HOUR TO DIAGNOSE ( WHICH WILL OF COURSE BE A MIN OF TWO HOURS ) AD THEN THE LABOR FOR TOTAL OF ABOUT $1,000. THIS SEEMS TO HAPPEN MORE OFTEN THE NOT. I'VE LOOKED ONLINE AND FOUND LOTS OF PEOPLE WITH THE SAME PROBLEM. FORTUNATELY THERE HAVE BEEN NO INJURIES OR DEATHS YET AS A RESULT THAT I'M AWARE OF. SO WHEN THERE IS A DEATH BECAUSE OF THIS, WHOSE IS GOING TO TELL THE FAMILY THAT THIS WAS APROBLEM THAT COULD HAVE BEEN AVOIDED OR FIXED. WE SHOULD HAVE TO WAIT FOR INJURY OR DEATH FOR ACTION TO BE TAKEN. THE DEALER ( LINCOLN MERCURY) SAYS ITS A DEFECTIVE PART ( MODULE). THIS IS A SAFETY ISSUE SINCE YOU CAN'T LEGALLY DRIVE A CAR @ NIGHT WITHOUT LIGHTS. PLEASE LOOK INTO THIS AND MAKE SOMETHING HAPPEN, PLEASE ! *TR

2004 MERCURY GRAND MARQUIS OUTSIDE LIGHTS GOES OFF AND ON INTERMITTENTLY. I HAVE 72,000 MILES ON MY CAR. IT SUDDENLY HAPPEN ONE DAY WHILE I WAS DRIVING AT NIGHT FROM MY SECOND JOB ON THE HIGHWAY. IT SCARED ME NEARLY TO DEATH AND IS VERY DANGEROUS. *TR

HEADLIGHTS GO OUT WHILE DRIVING. THEY WILL STAY OFF FOR A 2 OR 3 MIN. AND WILL COME BACK ON FOR A WHILE, THEN GO OFF AGAIN. I HAVE HAD THE LIGHT GO OFF IN A 5 MILE DRIVE 4 TIMES. THIS IS VERY DANGEROUS. I HAVE NOT HAD A CRASH, BUT WAS PULLED OVER BY THE POLICE. I HAVE REPLACED ONE PART, THE MULTI-PURPOSE SWITCH AND IT HAD NO EFFECT ON THE LIGHTS. AFTER SEVERAL DAYS OF RESEARCH I BELIEVE THE CAUSE IS THE LIGHT CONTROL MODULE, THIS PART RUNS FROM 400 TO OVER 700 DOLLARS. I AM ON A FIXED INCOME AND DO NOT HAVE THE MONEY TO FIX THIS PROBLEM. FORD SHOULD BE THE ONE TO REPLACE THE PART. THE HEADLIGHT SWITCH HAS NOTHING TO DO WITH THE LIGHTS GOING OUT. SINCE THE PURCHASE DATE THE SWITCH WAS ON AUTO, AFTER CHANGING THE M-P SWITCH I PUT THE HEADLIGHTS ON MANUAL ON/OFF. THIS PROBLEM HAS BEING GOING ON FOR OVER 2 MONTHS. THE PROBLEM HAS NOT BEEN FIXED. NO FUNDS. *TR

LOSS OF HEADLIGHTS WHILE NIGHT DRIVING. THIS HAPPENED ON TWO DIFFERENT OCCASIONS. CORRECTION REQUIRED WAS THE REPLACEMENT OF THE LIGHTING CONTROL MODULE (LCM) ON A 2004 MERCURY GRAND MARQUIS GS ($512,00). WE UNDERSTAND THIS PROBLEM ENTAILS 2000 TO 2007 FORD CROWN VICTORIA AND MERCURY MARQUIS MODELS ONLY, AND FORD MOTOR CO, HAS RECEIVED NUMEROUS COMPLAINTS ABOUT THIS HAPPENING BUT REFUSES TO ISSUE A RECALL NOTICE. *TR

I WAS DRIVING MY VEHICLE AND THE HEADLIGHTS JUST TURNED OFF. I COULD NOT SEE THE ROAD. IT LASTED FOR ABOUT A MINUTE WHERE I HAVE TO STOP ON THE SIDE OF THE ROAD AND WAIT. AFTER THAT THEY TURNED ON. THEN A FEW DAYS LATER THEY DID THE SAME THING. THIS HAS HAPPENED ABOUT 10 TIMES

HEADLIGHTS ON MY 2004 MERCURY GRAND MARQUIS STOPPED WORKING WHILE DRIVING. ALL OF THE FUSES ARE OK SO PROBLEM IS SOMEWHERE ELSE. PARKING LIGHTS AND BLINKERS STILL WORK. CAN HOLD THE HIGH BEAM LEVER TOWARDS THE DRIVER SEAT AND LIGHTS WILL COME ON BUT I MUST HOLD THE LEVER IN WHILE DRIVING WITH ONE HAND. *TR

THE HEADLIGHTS DO NOT STAY ON. THE LIGHTS MAY OR MAY NOT GO ON INITIALLY BUT CAN GO OUT AT ANY TIME MAKING DRIVING HAZARDOUS. THE ONLY WAY TO MAKE THEM LIGHT IS TO HOLD THE HANDLE IN THE "BRIGHT LIGHT" POSITION." I HAVE CONTACTED FORD WITH THE PROBLEM AND SEVERAL DEALERS TO NO AVAIL. THIS HAS BEEN HAPPENING FOR APPROXIMATELY A YEAR. A RELATED PROBLEM SEEMS TO BE THAT THE AIR CONDITIONER BLOWER STOPPED WORKING AND THE BRAKE LIGHT STAYS ON ALL THE TIME. JUDGING FROM THE COMPLAINTS I HAVE READ ON THE INTERNET, MANY PEOPLE HAVE ALL THREE PROBLEMS AT ONCE. *LN
