I was driving home on a dark country road with my granddaughter in the back who is 3 1/2. Had the high beams on. Lost headlights, dash lights, tail and break lights. If it wasn't for knowing the road and no other vehicle was around would have caused a bad wreck. There are a lot of lakes and hills around where I drive. Hit the breaks an came to a stop flipped the headlight switch a couple of times and changed to dim lights and everything came back on. This has happened before and it is only when the high beams are on. If this would of happened on a highway or with other vehicles around hate to think of what would happen. Ford says there is no recall on this problem. It has happened a few times but with the part being over 600. 00 and then paying someone to put it in. I can't afford to do anything.

While driving PA turnpike headlights cut off with no warning or any"flickering",replace,bulbs & fuses. Didn't help. . The headlights would not work on auto or manual. The only way we were able to safely get off highway was holding bright lite switch forward. This issue has made recalls of "certain models and certain,but not mine??? why aren't marquis and crown vic ,that are"outside" the recall car list,that have the same problem included???is it because not enough people injured or died?? so I'm stuck with a car I can only drive during the day !!! wth? I live on disability and was told it was a thousand dollar repair. . . Why wouldn't Mercury consider cars "outside" the recall years be treated like they were part of the recall,since all the symptoms are the same?? the dealer made me feel like I was trying to rip him off or scam him. The headlights cut off and back on at their discretion. . I don't fell safe driving my, fairly low mileage car(well maintained). Don't believe I'll be driving Ford products after this. If Ford would at least help those of us out here,by making the lcm sold to us at a free/at cost ,pricing !I feel that would be fair. I'm sure many cars not having this problem don't need "recalled". I would have thought Ford would be honest enough to stand by their products,and address this safety issue?! mail me one and I'll put it in. . . Thank you.

We had just left a funeral home and driving back home on a 4 lane road. We turned to avoid getting on the highway immediately and decided to take another route. As we were heading up this 2 lane road that was dark all of a sudden our headlights and instrument panel lights went out and cars coming at us were flashing their lights. I slowed down and was able to pull over to a side street. Sat there trying to determine why the lights were out. Turned the switch from the on position to the automatic position and the lights came back on. We drove all the way home on back roads to avoid getting on the interstate, not knowing if the lights would go out or not. Read the manual to see if we had missed anything and then got on the internet and saw the hundreds of people having the same thing happen to them. I will contact the dealer and see about fixing it but from what I have read, the light control module is bad and so are the replacements. I am hopeful that there is a newer improved model that is now being used. Thank god we were not on the highway or we could have been killed. This is a serious problem.
Driving along at night when headlights went out. Tried all switch positions with no results. Eventually found that I could get lights on by pulling and holding the high beam leaver. This problems happens without any warning. I am no longer driving this vehicle at night until I get it repaired.
While driving down the interstate my headlights cut off. My parking lights remained on. The only way to see the road was to hold the high beam switch. This is the fourth time that this has happened in the last 2 weeks. There is no pattern of occurrence. I investigated on the internet and there are multiple reports of this happening throughout the country. The headlight module seems to be the problem.
The contact owns a 2005 Mercury Grand Marquis. The contact stated that while driving approximately 40 mph, the headlights suddenly failed. The failure occurred intermittently four different times. The vehicle was not taken to the dealer for diagnostic testing. The vehicle was not repaired. The approximate failure mileage was 96,000. Updated 4/17/13 updated 05/14/2013.
The contact owns a 2005 Mercury Grand Marquis. While driving approximately 25 mph with the headlights activated, the contact noticed the headlights became inoperative. The high beams were activated and would only illuminate when the switch was manually hand held. The failure recurred whenever the headlights were in operation. The vehicle had not been diagnosed or repaired. The manufacturer was not notified of the problem. The approximate failure mileage was 39,120.
Headlights would not come on in the manual or automatic light switch mode. The only way to have headlights on is to hold high beam lever in the "flash more"( lever pulled toward driver). I found after a while if I kick my foot above the accelerator, the lights would come on and stay on for an undetermined time. Further diagnosis indicates a poor connection by moving one of the modules connectors.

I was driving to work at 5:50 am in the dark when on coming traffic began flashing their headlights at me. I then noticed that my headlights (which I always have set on automatic) had gone out without warning. I had to drive a short distance to find a safe place to pull off the road. I could not get the headlights to come on with the switch in either the automatic or manual settings. I repeatedly shut the car off and restarted it without any luck. I had to wait until the sun came up to continue driving to work. I goggled this headlight problem and found it is a very common failure of the lighting control module in the 2003-2005 Ford crown victoria and Mercury Grand Marquis. I contacted Ford motor CO. But was told there was no recall on these cars with this common and very dangerous defect and was directed to take my car to a Ford dealer for service. I personally think Ford should be responsible for repairing this defect with no cost to the customer.
Tl- the contact owns a 2005 Mercury Grand Marquis. The contact stated that while driving 50 mph, the headlights shut off independently. The contact had to use the high beam headlights to navigate the roadway. The vehicle was taken to a dealer and the contact was advised that the light control module would possibly require replacing. The vehicle was taken to an independent mechanic where the head lamp switch was replaced. The failure recurred. The vehicle was not further repaired. The failure mileage was 48,000 and the current mileage was 50,000. Kmj.
In October 2011, I was driving at night when my headlights went off. I pulled into a parking lot to investigate the problem. I got out and took a walk around the car and all the lights were working except the headlights. I turned the lights switch off for a few minutes and the lights came back on. The problem worsened and I found that I could hold the "momentary" high beam switch on and the headlights would work -- as long as I held the switch in the high beam position. The situation worsened, and now the headlights will not come on for any length of time. The problem has escalated from October 2011 until late may 2012. If I need to drive the car at night, I must hold the "momentary" high beam switch while I drive. Once in a while you can see the headlights come on because the lights get extremely bright. Then I can release the "momentary" high beam switch. The lights will only stay on for about 10 seconds and then go back off. My mechanic told me that many Mercury Grand Marquis and Ford crown victoria's around the model year of my car have this problem. He has traced the problem to something called the lighting control module. It seems to me that this is an engineering problem. Ford wants $600. 00 just for the part. If you search the internet for similar problems, you will find an abundance of very similar situations as I have described to you. Not everyone is reporting this problem. Please help!.
The headlights go and intermittently. They come on initially but only say on, on average, for about 5-10 minutes and will stay off for about 3-4 minutes. The headlight switch has been replaced but the problem is still occurring. No other mechanical work has been done since replacing the switch.
I was driving home and my headlights cut off with no warning at night, they came on again for a min. , but cut off this has happened 4 times since. I have to hold my bright switch down for a 30 min drive home. I have had a fuses checked, after looking on line it looks like several people have had this same issue, this is scary, considering I have 3 children.

The vehicle was taken to an independent mechanic for a diagnostic test. The mechanic stated that the headlight switch would have to be replaced.

At approximately 11:00 pm on 3/24/12, I suddenly lost my headlights as I was driving south through north carolina on interstate-95. I pulled into a rest area, and after a few minutes, my headlights came back on when I restarted the car. I drove for a few more hours without further incident. At approximately 8:00 pm on 3/25/12, I lost my headlights again while driving through florida. Fortunately, I was only a few miles away from my motel when the incident occurred. The next morning, 3/26/12, I took my car to an independently-owned garage, and the mechanic diagnosed the problem as a defective light control module. He was able to obtain a new module from a nearby Ford dealership and successfully install the module into my car. There is no question the light control module was defective because the mechanic was unable to restore my headlights by first trying to replace the headlight switch or the headlight dimmer switch. What's more, he was unable to get the defective light control module to respond to an external computer command. The repair cost $816. 77. I was concerned that I suddenly lost my headlights while driving on a busy interstate highway, but even more concerned when I heard a parts specialist at the Ford dealership that provided my new replacement light control module claim his dealership was replacing an average of three of these modules weekly on Ford crown victoria patrol cars being driven by local police. The idea of policeman losing their headlights during high speed pursuits at night made me very concerned. My concern was heightened when I started investigating the matter on the internet and read many stories similar to mine. A number of these stories suggested that Ford has known about these defective light control modules for quite some time and that a recall has long been in order. Thank you for your attention to this serious matter.

It was approx. 2:30am [night time] and I was driving on a rural state highway @ 65mph with the cruise control set. The headlights on my 2005 Mercury Grand Marquis suddely went out. The switch was set to automatic on / off. Visibility instantly became zero in the pitch black. . As I was 20 miles outside of town on a state highway in an unpopulated area with no lighting. . Not even moon light. I slammed on my breaks running off the roadway into the drainage ditch. . Taking over 100 feet to stop. After gaining my composure, I noticed that my dashlights were still working along with my yellow warning lights. I tried the headlights switch by changing it from off, to full on- to auto. . . With no success at first. But after 3-4 minutes the lights suddenly came back on and worked in both the auto & in the switched 'on' positions for 20-30 seconds and then shut off. So I knew the problem wasn't with a blown fuse. This continued to be the cycle. . The headlights would come on for 20-30 seconds and then shut off for several minutes before working again. By pulling the turn control / high beam lever toward me, I was able to get the passing light setting of my headlights to work and was able to drive back home. . . But this created a danger to vehicles I met. . As it blinded them. I couldn't turn off the bright passing beam without going dark on the roadway. Next morning I checked the internet about this problem and discovered that 1000's of other Mercury Grand Marquis owners have had this same problem. . That Mercury has known about this problem for years. . . With similar problems prior to 2005. Not only has Mercury knowingly endangered my and the other owners [and their faimlies] lives. . Mercury has created a very profitable income charging its customers close to $700 for a repair that they know is the result of a faulty factory installed headlight control module. This rates a recall!.
Let me start by saying this is a safety risk that could lead to loss of life. While driving at night, headlights went out. Instrument illumination stayed on. Headlight switch was cycled and the headlights cam back on. They turned off minutes later. After pulling over and cycling the bright lights and the headlamp switch, it was determined that driving with the signal light pulled back into bright-flash position was the only way to drive. This was after several pull-off-the-road events. We took the vehicle to the mechanic, who determined the headlight switch to be bad. $300 afterwards, the intermittent symptoms went away. However, the headlights never illuminated. From 12/11 through 5/12, the vehicle was driven only during the day -- occasionally at night, but with the turn signal pulled back to highbeam flash. After reviewing many internet posts, I discovered the light control module (lcm) was the suspect component. The dealership price for this component, as of 5/12, is $521. 67. I removed the lcm and opened it to inspect. After nothing was found (burned components, cold solder joints, etc. ), I reassembled and reinstalled it. After an operational check to see if reseating the connectors fix it, I discovered the headlight system fully functional. We'll see if the problem repeats itself. This problem was reported an many internet repair posts for 2003-2005 Ford crown vics and Grand Marquis.

While driving my car at in the very early morning both headlights failed on a curvy downhill road. I switched the headlight switch from the automatic position to the manual "on" position, but the headlights did not come back on. I pushed the high beam switch forward to the high beam postion but this failed to turn on the high beams. I pulled the the high beam switch back to the high beam "flash" position which did illuminate the high beams. I held the switch back in this position (to the displeasure of approaching drivers) until I found a safe place to pull over. I cycled the headlight switch numerous times with no effect. The light did finally come back on their own for a short time, but them went off again. This happened several times unti they finally did some back on for a lengthly period of time. The next day the same situation occured. At all times the other lights (dash, parking, etc) continued to operate. Very dangerous.

I own a 2003 Mercury Grand Marquis. The problem started with my headlights flicking on and off while driving at night and quickly progressed to turning off and not coming back on at all. I replaced the dashboard headlight control and they worked for about a week and then they started turning off again while driving but if I flicked my high beams they would come back on for about 15 min or so and go back off. After a couple of days of that they just quit working at all. Once again I replaced the dashboard switch to no avail.

All headlights quit without notice of any sort. After replacing bulbs and switches, I went directly to Ford. They charged almost $700. 00 to replace the "processor lighting control", which the service clerk explained was likely the problem. Since Ford knew this was a problem, why did they not recall the vehicles having this problem. We could have had a very serious accident.

I was driving down the raod at 70 mph and the headlights blinked off, all the lites went off, headlites, tailites, all. I turned the headlite switch on and off and nothing. I slowed and down and began to pull of the interstate and the lites blinked back on again. This occurred 3 more times on the way into work. I notified Ford, no assistance and the dealer replaced the lighting control module, stated they had seen a few of them. I saw a Chrysler had a problem and thought I should report mine. I notified Ford this was a safety item and they should issue a recall.
While driving on a back road on my way home from work, headlights went out and could not be turned back on. Headlights were in the auto mode when they went out, I switched to manual while braking so not to hit anything hard and they did not come back on. I pulled over and parked. I tried them again in about five minutes and they worked for about 10 minutes and then did the same thing. I have not had the car looked at yet, but on the internet found several similar stories and believe it is the light control module. I am shocked there has not been a recall based on all the complaints online about the 2003 Mercury Grand Marquis, I'm glad I wasn't asleep at the wheel when this happened to me! please do something about this, it is a serious problem!!!.
