As I was driving at night, my vehicle's low and high beams (lights) suddenly cut off. Unexpectedly, the road I was traveling became very dark because I live in rural areas in West Virginia. Unfortunately, a second later, my car ran over a small boulder on the side on the road causing a damage (small cracks) at the bottom right hand side of my bumper. Nevertheless, I put the emergency lights on until I returned home right away. Earlier this week, I used the car again without any lights issues. However a day later, the issue returned again. This time I was traveling in the highway at 60 miles per hour. All low/high beam lights cut off. My only solution was to hold the "flash to pass" lever towards me, and the high beam lights would turn on. However, it is extremely cumbersome driving this way. I've been told by many mechanics that the main culprit is the lighting control module (lcm) and this safety issue has become extremely common in Grand Marquis especially 2005 models. Consumers and perhaps the government may need to further intervene, so Ford can do something about this safety/hazardous. In my case, my bottom bumper suffered, but it could have been worse - it could easily cause an accident at any given time. Currently, I only use my vehicle during the daylight hours. I've been told that repairs can exceed $700 or more and in some instances, the issue returns within a few months after replacing this part. This electrical issue should perhaps be further investigated as the lcm could be the main culprit, but something else could also be triggering the lcm to fail. Thank you greatly!

2005 Mercury Grand Marquis. Consumer writes in regards to the lighting control module issues. The consumer stated failure of the lighting control module, cause the headlights to go out without warning. The only way to turn them back on, was to reach under the dashboard and tap the affected module which worked sometimes and sometimes it didn't. the part was ordered on November 6, 2014. However, the dealer had no idea when the ship would be for the part.

I was driving at night and turning into a dark driveway with my lights functioning fine and they unexpectedly went out. It was an intermittent problem and would happen without warning while driving with the lights on. We replaced the light switch and thought the problem had been fixed; the lights seemed to function properly for about three weeks. The last time this happened, recently, I was on the interstate traveling at 73 mph, passing a semitrailer, when the lights went out. Terrifying! fortunately, I was able to get past the semi and pull over to the shoulder, throw on my flashers, and fiddle with the light switch until the lights came back on.

My headlights will not come on at times or just come on for a couple of minutes and then they gone. I have gotten so many tickets for driving with my high beams and it's seem like the manufacturer don't care at all.

I went to have my lights fixed due to a traffic violation for high beams.I took it to be repaired at mall of Georgia Ford. My low beams would not turn on. They replaced the wrong part when there was a warranty out for the lighting module. They refused to fix issue and my low beams continued not to work. In order to make the lights work you have to hold down the high beam lever.

The issue described in PE08066 happened to me last night. While driving at approx 50 mph my headlights tuned off spontaneously. Luckily I had other cars in front and behind me and could still see the road because of their lights. My turn signal functioned when I signaled I was pulling over, and it appeared my side markers were still on (yellow glow off cars around me). I do not know if my tail lights were still on. I turned my headlight dial from automatic to manual headlights, and there was no difference. Then, my headlights came back on spontaneously. They were out for a total for 10-15 second. This is very dangerous.

Nighttime, turned car off in drive through line at fast food place 185 miles from home. Have light switch on automatic. Turned car on and drove off only to realize that my headlights were not on. Stopped in adjacent parking lot and began playing with the switch, turning car off and on, trying to figure out how to drive three hours with no lights... high beam flash mode would function, but would be very unsafe on two lane highway. Suddenly began working on own. Stopped one time in route home but again played with it till it came on again. Fear this is a big safety issue.

Headlights intermittently fail without warning and cannot be regained with headlight switch. In fact, no position operates with the headlight switch - no parking lights, no headlights, etc. Only after a seemingly random cooling period will the module allow the circuit to re-engage. Ford issued recall 14N01 but to date has not provided car dealers nor retail customers with a replacement switch. One Ford dealer ( tom peck Ford 608-676-2273) says back orders are unfilled. No Ford dealers nor after market auto parts companies are able to obtain the part. Even if the vehicle owner attempts to purchase and replace the small cigarette sized box called a "light control module" out of pocket, rather than waiting on Ford, it cannot be found on the market in companies like advance auto parts. This is not intended as a shrill complaint about Ford. But the danger is huge to the driver and other vehicles when this part randomly causes all power to be lost to the headlights. At highway speeds, it is very difficult to maintain control of the vehicle to a stop in total darkness. The part failure is increasing in frequency, and is has become a safety menace. Some Ford or Mercury owners may not be affluent enough to own a second vehicle to drive only at night. No drivers want to encounter another vehicle with that kind of malfunction. In fact, all the vehicles with that known hazard should be off the road at night. No doubt Ford has been addressing the light control module issue since the April 2014 recall, but certainly not with the urgency required.

Headlights suddenly went out while driving on interstate highway at night. I had received a "customer satisfaction program" recall from Ford Motor Company in April of this year advising that the "lighting control module" (lcm) could fail causing the loss of headlights. I took my car to the local dealership the next day. The car was examined, the defect was acknowledged, and the replacement lcm was ordered. It has now been well over two months since the lcm was ordered. The dealership claims that the supply of the lcm is short due to the massive number of defects. I have pleaded for relief by emailing Ford but they have not seen fit to even respond to my communication. It is beyond my comprehension how any prudent person, corporation, or administration could categorize losing the headlights as anything other than a safety issue! it is for this reason that little action is being taken to correct this potentially fatal situation.

Headlights went out. I received a notice from Ford in April of 2014 there was an electrical/lights problem and they would repair if owner actually had this problem. I had no problem until Oct 2014. Went to my dealer quick lane/Ford in topeka, ks. They reported that part has been on back order since may of 2014. Contact another Ford dealer who reported same. Light have regularly gone off since that time. What is a reasonable time to expect that they would have correct parts to replace as neither dealer had any report as to when part might come. VIN: [xxx] field service action number: 14N01 fsa title: Extended warranty coverage on lighting control module.

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.

This is a complaint on Ford Motor Co. We received a letter for a recall in April, for the lighting control module. Not long after, the headlights went out. Nothing could get them back on. We took the vehicle to the dealer. The stated they did not have the part. That was over two months ago. The dealer still does not have the part. So the car has been sitting there for that length of time. We could not take a chance of driving it without any lights. How can the dealer get the part from co? it is ridiculous to send out a recall letter and then not supply the part....updated 10/22/14

Failed lamp control module, headlights fail to work, only high beams work when lever is held in flash position. Ford issued an extended warranty program 14no1 in the spring of 2104 for just this part for 15 years or 250,000 miles. No replacement parts are available in the usa. The dealer says they have a waiting list that goes back six months. Have talked to regional managers in dearborn, mich. All say they have no idea of a shipping date, much less a delivery date, from supplier. Won't indicate how many vehicles are effected, but has to be many due to extended warranty program. Their solution is if the lights don't come on or go out while driving is to hit under the dash to the right of the steering column and they should come on. This means there are cars on the road that people are driving during daylight hours knowing that their cars headlights are not working correctly, but no parts available from Ford to honor warranty. This means that cars are being used that may not be legal to drive in the rain (most states have headlight on if raining law) and also will not pass state inspection. I understand that parts are not always readily available, but should be available in several days. If this is a known problem, why are there no parts? no other help or loaner vehicle program is available.
