First check the light bulbs if they are not the reason then, Welcome to the ford world, there is a thing called LCM (light control module in the grand marquis crown vics and lincoln town cars, sometime they go bad, your best bet before you look for replacing the LCM is to look for the headlight fuse and the relay, when you are sure it is not these two, then you can be sure its the LCM

Testimonial: "If you have a 1999-2011 Mercury Marquis, Mercury Marauder, or Crown Victoria, and your headlights and or tail lights don't work, Ford just finally extended the warranty on your LCM (Lighting Control Module) for free - both parts and labor and will install a new one for free! Ford has extended the warranty to 15 years/250,000 miles.  It must be done at a Ford Dealer and the fix is free.  Call your local ford Dealer and tell them you need to make  an appointment because your headlights don't work and Ford has extended your warranty on the LCM.  Tell them it is the Customer Satisfaction Program 14N01.  Have your Vin number ready as they will ask for it.  You don't have to be the original owner.  If they act like they don't know what you are talking about ask to talk to the manager or tell them to call Ford Motor Company and ask them, or you can call Ford yourself.  We had ours done at a Ford dealer in August of 2014 in Scottsdale, AZ.   It is a 15 year warranty and if  you have a 1999, the deadline might have passed, but call them and ask them to see if it has.  Maybe it hasn't."

SOURCE: headlights and interior dash lights flickering mercury marquis

while this occurs; do you hear clicking near your right foot area while sitting in the drivers seat? it may be heard very faint (you may have to remove the sound barrier panel under the dash first. Does this problem only happen with "Automatic" lights? Does it happen while in the parking lamps position? I wish to suggest the light switch itself, or the connector at that switch may be loose, or the negative supplying the switch could be loose. But more likely, you should check for a defective BCM, or loose connections to it, located between the lower left of the ash tray area and the accerator petal area (the relay inside on the circuit board may have a bad solder connection to it) ... or the relay inside is bad period.

SOURCE: location of headlight relay on 1993 mercury grand

that is caused by a "circuit breaker" not a relay. when it starts flashing, carefully go over the harness from the firewall to the rf headlamp, there is a short somewhere.

SOURCE: 2003 mercury grand marquis headlights will cut out

My 2003 Mercury Grand Marquis has the same problem. We found out it was the headlight module located under the dash above the gas pedal. The black box has wire connectors coming out of the back. Hitting the box worked for a little while, then I had to reach in the back and wiggle the wire harness. The dealership wants 500.00 to replace the unit. I consider Highway Robbery! They have installed a faulty piece of equipment on my Luxury car that could easily be life threatening but we know it won't be recalled until someone dies because of it. My husband was able to remove the unit and looked it over it had two circuit boards and he was unable to visibly see any problem or loose wire. He cleaned the connectors and used some electrical terminal grease on the wires, this improved it for a short time. The problem still exsists. I have sat for 30 minutes or more waiting for them to go through the On/Off cycle till they stay on for the 45 minute ride home from work. I have beat the box with my flashlight (maglights handle the abuse, my fingers and nails don't) till it came loose from the brackets that hold it. I leave my car running while pumping gas, short shopping trips and start it 20 or 30 minutes early before leaving for work. It is frustrating and dangerous. If this is the kind of quality in our American made cars it's no wonder they needed a BailOut! The only thing we have found to "fix" it is to find a used part that could possibly have the same problem shortly down the road or pay the theives at the dealership to replace it.

97 grand marquis high beam stop work but the light well show up on dash that its on but lights dont come on


Does the high beam work on `flash to pass' feature? That's when you pull the lever toward you to flash your high beams.
If they light up while you pull your lever, it's probably a bad headlight connection at the switch on the dash,OR a bad headlight switch(very expensive if it has the delay feature,which most of them do.
If your lghts DON'T brighten when you pull the lever toward you,it might just be bad bulbs......one goes out and you don't notice it, and then when the other goes out,you NOTICE it. don-ohio (:^)

Headlights don't work unless you hold high beams


Check the headlight Relay and/or fuses - should be in the fuse panel.

Headlights come on for a 10 minutes and then turn off; dash lights, turn signal, passing signal all work etc.


There is actually a possible recall on this issue as it is a known problem with the LCM, or Lights Control Module. Go to the following site:
http://www.arfc.org/complaints/2003/mercury/grand_marquis/

This is one of the complaints:
HELLO, WE HAVE A 2003 MERCURY GRAND MARQUIS THAT HAS A PROBLEM WITH THE HEAD LIGHTS SHUTTING OFF AT RANDOM TIMES. NOTHING GAVE WARING TO THIS PROBLEM HAPPENING, WE BOUGHT THE CAR USED, AND WAS JUST FINE FOR A YEAR, THEN ALL OF A SUDDEN ONE DAY THE HEADLIGHTS JUST GO OUT. THE FIRST TIME IT HAPPENED WAS ABOUT 6 MONTHS AGO(3-1-10). NOW EVERYTIME IT IS DRIVEN WITH THE HEADLIGHTS ON, IT IS GUARANTEED TO HAPPEN AT LEAST ONCE AND SOMETIMES UP TO 5 TIMES JUST IN 3 MILES OF DRIVING ON MY WIFES WAY HOME FROM WORK. THE ONLY WAY TO GET THE LIGHTS BACK ON AFTER THEY GO OUT IS TO PULL OVER TO THE SIDE OF THE ROAD, SHUT THE CAR OFF, LET SIT FOR A FEW MIN, THEN START AND THEY WORK AGAIN FOR A BIT. THIS IS OVERALL VERY DANGEROUS AND SUPRISING THAT WE HAVE NOT BEEN IN AN ACCIDENT OR RECIEVED A TICKET YET! I AM A ACTIVE MEMBER ON A CROWN VICTORIA FORUM, AND WITH LITTLE SEACHING ON THAT SITE OR GOOGLE YOU WILL SEE TONS OF REPORTS OF THIS BEING A VERY COMMON PROBLEM ON THE 2003-2005 CROWN VICTORIA, GRAND MARQUIS, AND MERCURY MARAUDER. WITH THE HELP OF OTHER MEBERS ON THAT FORUM IT WAS FOUND TO BE A FAULTY LCM(LIGHTING CONTROL MODULE) WHICH HAS A PROBLEM WITH OVERHEATING LIGHTING RELAYS. THE ONLY WAY TO REMEDY THIS PROBLEM IS TO PURCHAS A NEW LCM FOR ANYWHERE BETWEEN $250 AND $600 WITH NO GUARANTEE HOW LONG THAT PART WILL LAST. I ACTUALLY PURCHASED A NEW ONE TODAY. VERY EXPENSIVE FIX JUST FOR THE USE OF HEADLIGHTS, BUT I VALUE MY FAMILIES SAFETY MORE. I WILL BE KEEPING MY OLD LCM TO POSSIBLY HAVE IT REPAIRED FOR WHEN MY NEW PART FAILS AGAIN. THANKS SO MUCH.

Headlights constantly go on and off, all other lights stay on my 2003 mercury grand marquis. where are the relays located?


Sounds like a bad headlight switch, the 2003 mercury marquis has a circuit breaker built into the headlight switch that goes bad.
Check with your mercury dealer for a headlight switch recall.

Headlights cut out after being on 10 to 15 minutes


I had the same exact problem. I found that I could make the lights come on by pushing on the top connector on the front side of the lighting control module (LCM). I pulled the connector off, cleaned it and put it back together with some dielectric grease. Only time will tell if I fixed it. On my car, it would only have problems after the headlights had been on for about 3 hours; kind of hard to re-create.
