HEADLIGHTS KEEP CUTTING IN AND OUT. TURNING ON AND OFF WHILE DRIVING. GOING 65 DOWN AN EXPRESSWAY AND HAVING YOUR HEADLIGHTS JUST SHUT OFF IS NOT THE SAFEST OF CONDITIONS. I HAVE BEEN TOLD THE HEADLIGHT MODULE HAS A NOTED ISSUE ON OTHER FORD VEHICLES AND ITS VERY DANGEROUS. I HAD MY 5 YEAR OLD NIECE IN THE CAR WITH ME WHEN THIS HAPPENED. *TR

I WAS DRIVING ON A TWO LANE ROAD AFTER DARK WHEN SUDDENLY THE HEADLIGHTS WENT OUT AND A VERY LOUD BUZZING NOISE OCCURRED SIMULTANEOUSLY IN THE DASH. I WAS ABLE TO SLOW DOWN SAFELY BECAUSE TWO CARS WERE MEETING US AND THEIR LIGHTS AFFORDED ENOUGH VISION TO KEEP MY CAR IN MY LANE. I PULLED OFF THE ROAD AND TRIED VARIOUS POSITIONS WITH THE LIGHT SWITCH AND HIGH AND LOW BEAM SWITCH. ALL THE LIGHTING SEEMED TO WORK EXCEPT THE HEADLIGHTS. FINALLY, I TURNED OFF THE IGNITION. WHEN I RESTARTED THE CAR THE LIGHTS CAME BACK ON AND WE DROVE ON HOME VERY CAREFULLY. THEY HAVE WORKED SINCE BUT I AM VERY WARY OF DRIVING AFTER DARK. THE BUZZING NOISE QUIT, ALSO, AND HAS NOT RETURNED. *JS

2000 MERCURY GRAND MARQUIS - HEADLIGHTS AND TAILLIGHTS GO ON AND OFF THROUGHOUT THE NIGHT WHILE THE VEHICLE IS PARKED AND THE ENGINE IS OFF. *TR

DRIVING AT NIGHT WITH HIGH BEAMS ON. AFTER AN EXTENDED TIME ,AT LEAST AN HOUR, HEADLIGHTS WENT OFF. SWITCHED TO LO BEAMS AND THEY CAME ON, SWITCHED BACK TO HIGH BEAMS AND THEY WENT OFF AGAIN. I HAVE A 1994 GRAND MARQUIS AND IT DOES THE EXACT SAME THING. REPLACED THE HEADLIGHT BREAKER AND STILL HAVE THE PROBLEM. *TR

CRUISE CONTROL WORKS WHEN IT WANTS TO....SOME DAYS IT WILL WORK, OTHER DAYS IT WON'T...ALSO HAD PROBLEM WITH SIGNAL LIGHT BLINKING FASTER AT TIMES THAN AT OTHERS...HAD THAT PARTICULAR PROBLEM FIXED BY CHANGING THE "LIGHT MODULE" FOR $500...NOW ITS THE CRUISE CONTROL...ONE MORE PROBLEM AND I'M SELLING THE CAR....*AK

HEADLIGHTS AND INTERIOR LIGHTS COME ON AFTER THE VEHICLE WAS SHUT OFF FOR A LONG PERIOD OF TIME. CONSUMER WAS CONCERNED THAT THE BATTERY SYSTEM WILL WEAR DOWN. *AK

CONSUMER WAS DRIVING AT 55 MPH AND THE LIGHTS CUT OFF. CONSUMER STOPPED IN THE MIDDLE OF THE ROAD, AND THE LIGHTS CAME ON. THEY CONTINUED TO SHUT OFF AND ON AT LEAST FOUR MORE TIMES BEFORE THE CONSUMER COULD DRIVE HOME.*AK *TC

WHILE BEING PARKED THE HEADLIGHTS WILL INTERMITTENTLY COME ON AND OFF WITHOUT A KEY BEING IN THE IGNITION. CONSUMER STATED THE DEALER CHANGED THE HEADLIGHT SWITCH. HOWEVER, WHILE DRIVING AT NIGHT THE HEADLIGHTS COMPLETELY WENT OUT. THE CONSUMER WAS DRIVING AT 65 MPH.

WHEN EVER THE CAR IS DROVE WITH ITS LIGHTS ON BRIGHT, AFTER 5-10 MINUTES OF DRIVING, THE LIGHTS START TO FLICKER AND EVERY THING IN THE DASH GOES OUT ALONG WITH THE LIGHTS, WHICH LEAVES YOU IN TOTAL DARKNESS, WHICH IS VERY DANGEROUS WHEN DRIVING AT NIGHT. SO FAR THERE HAS NOT BEEN ANY ACCIDENTS OR INJURIES FROM THIS, I WOULD LIKE TO KNOW WHY THIS HAPPENS AND HOW IT CAN BE CORRECTED? THIS DOES NOT HAPPEN WITH THE DIMMS ON WHILE DRIVING...

CONSUMER STATES WHILE USING HEADLIGHTS AND WITHOUT ANY INDICATION HEADLIGHTS FLICKER FROM HIGH TO LOW, AND THE AC RUN FAST AND SLOW. DEALER HAS BEEN CONTACTED.*AK *CB

HEADLIGHTS ARE TOO DIM TO BE DRIVING AT NIGHT.*AKTHE CONSUMER BELIEVES THAT THE HEADLAMPS ARE NOT ADEQUATE FOR NIGHT DRIVING, THEY ARE VERY DIM AND DON'T GO THE DISTANCE. NLM
