While driving down the highway @ 65 mph the headlights suddenly went out causing a very dangerous situation. I tried the switch in every position to no avail the only solution was to use the flash to pass bar. I safely pulled off the road and tried restarting the car and moving the switch to different positions, nothing would work. The only way to use the lights is the flash to pass (bright lights) switch which causes not only a safety hazard to my family and other drivers but is against the law to drive with only bright lights. Ford has issued (customer satisfaction program 14n01) which is a step in the right direction but the dealerships all say that the lcm is on backorder and will be at least 45 days to receive this safety hazard part. Mt family is now stuck in a vehicle that can only be safely driven during daylight hours. Please help, parts stores have these parts and Ford should have to be required to purchase them if they can not provide the parts until 45 days later. Is this safety issue going to take someone dying before it is rectified?.

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.

The headlights would not come on even tried to turn them on manually. Had to drive home holding the dimmer switch back to have high beams.
The headlights on my 2003 Mercury Grand Marquis have stopped working. This has been an intermittent problem. The most recent issue left my wife and mother in law stranded along the roadside. The first time I thought it was the switch in the steering column because after working the blinkers the lights started working. The next time my wife was driving on the interstate highway and the lights just went off at interstate speeds. It seems this is a common issue and has stranded others.

At about 8 pm, I was driving on an interstate in heavy traffic when the headlights went out. I was able to pull off the interstate. I turned the headlight switch on and off, but the headlights did not come back on. After a few minutes, the headlights just came back on. I turned on my blinker to get back on the interstate and the headlights went off again. My husband and I swapped seats and he took over the driving. The lights came back on and he pulled onto the interstate. The lights went off again and as long as he pulled the blinker towards him, then we had bright lights. Whenever he released the blinker, the lights went out. After driving for about 10 minutes with the bright lights on, the dim headlights came back on and stayed on for the next hour as we drove home. He was told at a Ford dealership that it was the light switch, so he replaced the switch. The next night the headlights went off again. I pulled off the road for a few minutes and the lights came back on and stayed on until we got home about 20 minutes later. We have not driven the car at night since then. We have since learned via this site that there is a problem with the light control module. The service man in the Ford parts department said it was his experience that when this happened it was the light switch. So we spent $137 on a part that we did not need.
I drive on the highway from to work. During the winter months, it is dark at 6 am. This morning, as I usually do, the light switch was on and it was on low beams. Suddenly, the headlights went out. I pulled over and stopped. The side markers and the parking lights were on. I sat for a few minutes to decide how to get home with no lights. Then the headlights came back on. I took a chance, they remained on, that day. It would occur periodically then daily, sometimes two (2) to three (3) times on the drive to work.
We were driving on rte 202 in chalfont, PA and turned onto rte 152 heading south. While driving along an unlit part of the road, the headlights went out. The switch was not working to turn on or off. I went off the road but was able to recover safely. I turned the car around and headed home. Lights came on and off again in about 3 minutes. Lights continue to go off randomly when car is driven at night time.
I was driving on the interstate when the headlights went off suddenly. The only way I could get lights was by holding the dimmer switch toward me on bright. Then it would suddenly click back on and then go off again. It was very scary. After looking this up on the internet this same safety issue has been reported numerous times with the exact same complaint. This is very dangerous.
I was traveling down the highway at 55 when I noticed my headlights were not reflecting off the road signs. I pulled over and checked my lights and noticed I only had parking lights not headlights at all. I got back in the car and tried the light switch but nothing came on. I had to have the car towed and was told the lcm lighting control module has failed. At a cost of 400 dollars. Safety hazard Ford knows about but is doing nothing about it.
Driving down the road and the headlights went out. All other lights work fine, but the headlights work intermittently. I have to use the bright lights and hold the switch while driving in order to be able to drive at night and that is just crazy. I'm blinding everyone I pass and it's very hard to drive that way.
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.
Tl- the contact owns a 2005 Mercury Grand Marquis. The contact stated while driving 10 mph the headlights failed. He was able to gently shake the switch and the lights came back on. The failure recurred numerous times. A dealer was notified and suggested that it may be the headlight switch that was the cause of the failure. The vehicle had not been repaired. The failure and current mileage was 79,100. Dt.
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. 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!.
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 contact owns a 2005 Mercury Grand Marquis. The contact stated that the headlights stopped illuminating while driving approximately 35 mph. The vehicle was taken to an independent mechanic for a diagnostic test. The mechanic stated that the headlight switch would have to be replaced. The manufacturer was made aware of the failure and stated that the part was not in stock. The vehicle was not repaired. The VIN was not available. The approximate failure mileage was 38,000.
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.
