My brother was visiting for my son's wedding and used our mother's car for transportation. He found that the headlights would not come on, and eventually found that holding the high beam switch "on", the lights worked. At the dealership he was told there was likely a recall to fix this. Since he has gone back home, I have been researching this for my mother. I found a closed "safety" issue, number pe08066, which is exactly what he experienced. Although you have a very low number of complaints listed, consider this: most of these cars are purchased by older people, many mechanically incapable in addition to being unsavvy with computers and the internet, and tend to drive it less, especially at night, so the issue would not be noticeable for quite some time. If they did experience this, they probably paid some serious money to Ford dealers to get it fixed, not realizing that this is a huge safety issue and this should be fixed for free under warranty before failure of the module - the TSB talks about failure of the module. Well, my brother took it in for inspection with this faulty module, and it passed, so then do they not consider it "failed"? mother is 91 years old and would probably panic if the lights went out while she was driving it. This is a major safety issue, and should be rated higher to get the warranty work done!!! I plan to follow up with the same dealer and see what they have to say about this. My suspicion is that until it fails she will have to pay for this fix, which is not cheap. This is ridiculous. Listing my information instead of hers as she needs our help to deal with this kind of annoyance.

While driving on the expressway with the headlights on auto-on, the headlights on our vehicle turned off. I attempted to turn them on manually, but they would not come on. This situation has happened several times and creates a very dangerous situation. They do eventually come on, sometimes when playing with the light switch manually and sometimes not until you stop, turn the vehicle off and then turn the vehicle back on again. Occurrences are random. There is no steady pattern. Thanks.

The headlights turned off while on the freeway. Since then it's happening more frequently. Now it's multiple times each morning on the 35 minute trip to work. Temporary solution is to manually hold the momentary brights switch. Holding this switch while driving is annoying, and unsafe since that it on the same lever as the turn signals.

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.

In early June the headlights started going out with no warning. They would also flash on and off when the wipers were on. Took the car to a mechanic and he said the lcm was bad. $500 to repair. Was looking online for a lcm and seen that Ford was extending their warranty on the lcm under the number 14n01. Looked at my Ford recall letters and seen that Ford sent out this warranty 14n01 to me in April of 2014. Took car to the dealer on 11 August and they confirmed the lcm was bad and would replace it. It is now 15 September and the parts are still not available. Now the wipers and wiper washer come on even when the wiper switch is off. Lights come on when their not supposed to. Anti-skid was also flashing on and off. Car may be unsafe to drive but I need transportation for work and cannot always use my wife's car. Ford will not offer a car for me to use. Should this be a safety recall? do I have any options with Ford?.

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.

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.

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.

The failure mileage was 48,000 and the current mileage was 50,000. Kmj.
