My 2003 Mercury Grand Marquis has had an issue with the lighting module for the headlights. The headlights will not turn on anymore and from what I see from others complaints about this model is that the majority of the complaints with this vehicle are with the same issue! I really hope that this issue becomes a recall since obviously they are aware of how many people are having this problem. Do you know how hard it is not to be able to drive at night"! let alone when it's rainy or foggy out. I have young children what if theres an emergency?? this issue needs to be addressed before more people get into an accident! are they waiting for someone to die first!" another issue I have is with the windshield wipers- they only have one speed- fast. I don't know why they wouldn't make them with slower settings, every time it rains lightly I have to turn them on for a second and off repeatedly because there aren't any slower settings. I like the comfort of my Grand Marquis but these issues really need to get resolved or I'll be forced to by another vehicle and if they don't do a recall on the exterior lights I will never buy another vehicle from Ford Motor Company because it will show that they really don't care about people's safety!

While driving home my head lights went out. I tried to pull over when I noticed but it was dark and not a good place to stop a vehicle. I found my hazards and tried to creep to a safer spot. Luckily I made it out of this safely, I live in san diego where there's a lot a traffic and some areas are not well lit or suited to pull over. I felt like this was a hazard that could have caused an accident and risked my safety. I was shocked when I got home and read on the internet that this is the most common problem for a 2003 Mercury. This safety hazard needs to be addressed and corrected. Thank you

Intermittent failure of headlights throughout life of vehicle. Headlights cease to work; high beams work if flash to pass lever is continuously pressed. On 5/18/15, complete headlight failure, speed on drive home estimated at 5 mph max as roads were dark and driving with flash to pass lever activated requires one handed driving. Very unsafe. Symptoms consistent with lcm failure reported by multiple marquis and Crown Victoria owners and Ford bulletin 14N01. Contacted Ford and stated we never received 14N01 - Ford customer service stated they were unable to provide copy of 14N01 !" and referred to dealer. Contacted dealer who stated I would need to physically come to dealership for a copy of 14N01, if the dealer diagnosed a 14N01 issue, the repair would take two days. I asked if a loaner would be provided. Dealer stated no and dealer stated they could not order the part ahead of diagnosing the vehicle per my request to expedite lcm replacement. The Grand Marquis and Crown Victoria 2003-2005 should be recalled. Has anyone at Ford ever driven without headlights? this is a safety issue which is a recall issue, not a stealth Ford customer satisfaction campaign attempt at pacifying consumers with non working headlights. This problem was originally identified in 2008; why are consumers driving cars with malfunctioning headlights in 2015? why does a Ford owner have to obtain a copy of 14N01 on the NHTSA website versus from Ford via email" so much for the "go further" promises of Ford; we car owners aren't "going further" with no headlights.

While driving at night the head lights suddenly went out. The only way the lights would work after that is if you hold the high beam lever back.

The headlights would turn on intermittently and then began to fail completely. With the dash switch in the proper place, the headlights would not come on. The high beams would continue to work, but the low beams would not. A Ford dealership declared that it was a bad lighting control module.

My husband and I have had to make other arrangements for us getting back and forth to work after the headlights stopped working on this car. We went to the dealership who stated the part was on back order. We were just able to get the part placed on 1/21/2015 and it worked for the first hour. We took it back on 1/22/2015 and was told that the lighting controls (the switch that turns the light on auto, off etc) is not their problem. It seems they allow these problems to occur long enough to allow it to effect other things on the car then state there was only one problem approved without the out of pocket. However we had no problems until the headlights stopped working. The next thing that went were the dash board lights and now the brake lights. How do we know that depending upon the timeframe problem exists, it may have an adverse affect on other things? this has been a huge inconvenience and it seems they want a fatality before something is done about it.

Update: After reading the headlight issues on this site, having had the same problem myself, I took my Mercury to mechanics and explained what I've been reading. They said the lighting control module was on a lengthy back-order. However, they were able to find a broken solder joint on the lcm, which they repaired for $170. This repair lasted 3 months and, as of 1/17/2015, headlights randomly shut off, again with only the 'flash to pass' stick pulled in to illuminate the high beams.

My headlights went out while driving a few times. I took it in to the dealer (after local shop said it would be expensive, but may be under warranty). The dealer said on November 18th that the lcm is covered under warranty, however it may take a few weeks. The problem is getting progressively worse. The dealer's suggestion for workaround is to use the "flash-to-pass" lever, which momentarily turns on high beam lights. This is not a practical solution, holding the passing lights during a 45 minute drive to work every day. The dealer refuses to provide a rental/loaner vehicle. I'm concerned with the long term effects on the "flash-to-pass", which may go out as well, as it is not designed for continual use like this. I have to drive to work in the dark every morning, dealing with intermittent headlights, and trying to manually hold the flash-to-pass lights. This is a dangerous situation which should be resolved immediately!

The headlights would not come on. The only way to drive home was to hold down the high beam lever the entire time, there are many complaints about this situation online with this vehicle and this is a severe safety issue. This car is owned by my 84 year old mother, lets get this recall done so no one gets hurt.

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.

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.
