Turn Signal problems of the 2005 Mercury Grand Marquis

My husband and I were on vacation on August 14th 2015 when we were going to leave our location, we turned car on and headlights; when we noticed headlights would not turn on at all. We manually turned the knob multiple times and no lights turned on. When he pulled turn signal lever back toward him, we came to a conclusion the only way we could travel was with the manual high beams on. He had to hold the lever the entire way to our next location in the mountains which was dangerous for us as well as other drivers. The headlights somehow came back on. And on August 26 2015 I just had the same problem with headlights not working unless holding back the manual high beams lever. This time they did not come back on. Not only am I as a driver blinding people with high beams, I am risking my driving by holding down a lever while trying to drive. The lever hits the steering wheel and makes it difficult to turn the wheel. This is a serious problem that many others with this year make and model are experiencing. This needs to be addressed and fixed.

Similar to events as published in NHTSA action number pe08066, I was driving on the interstate at night and the headlights suddenly went dark. No warning, just went out. Pulled off onto shoulder and could not avoid sliding off the road - very dangerous. Finally figured out if you pull the turn signal lever all the way towards you it will turn the bright headlights on, but you have to hold it on position . . If you let go the headlights go back out. The problem is intermittent and appears without warning. 1000's of complaints about this same issue all over the internet - so I can't believe the agency closed the original investigation?? what could be more dangerous than losing your headlights at night?? there should be an immediate recall from Ford motor CO. On this issue! my local Ford dealer and communications to Ford motor CO. Have produced no help. This is approximately a $700 repair at the dealership for a proven defective "lighting control module". This is a "safety-related" issue if there ever was one!.

The headlights turn off randomly. The running lights stay on but the normal headlights will go off randomly and then come back on several to tens of minutes later. I can hear a clicking sound when the lights do go off and back on. When the lights do go off, I can hold the high beams on if I hold the stick toward me. Sometimes initiating a turn signal will cause the headlights to come back on.

I was returning home with my wife from a trip to charleston, SC, at about 10:00 pm, driving at 60 mph, when my headlights suddenly shut off. That happens in the vicinity of awendaw and there are no street lights in the area. Both my wife and I screamed in panick while I was trying to slow down the car and staying in my lane on the highway. I was thankful that the turn signals, marker lights and brake lights still worked, so any other cars would be able to see me. When I finally pulled up the side of the road without any mishaps, I inspected the car and found out that all the fuses were good. I then restarted the car and still did not get my headlights to come on. I played with the turn signal/ low beam/high beam lever and got the flashing high beam position to work, so I drove home to myrtle beach holding the flashing high beam lever up to light my way. Otherwise, I would have to hire a taxi, spend the night in the nearest hotel to wait for daylight to resume my trilp home. Apparently, the problem with the headlights shutting off without warning while driving at night comes from the lighting control module installed the the 2005 Mercury Grand Marquis that malfunctions when the cars reached an average mileage of 69,000 miles (some as early as 30,000 miles, up to 114,000 miles documented).

The lights were on in normal mode when I heard a click and they suddenly cut out. I was driving slowly in town and was able to pull over; I discovered that I could hold the turn signal control signal for the passing brights and get light; otherwise no lighting would turn on regardless of attempts to change the lighting mode and restarting the car. Eventually the lights came back days later, but have continued to cut out intermittently ever since. This is a major safety hazard as there is no predicting the failure, and the brights are not good to have to hold to use.

The contact owns a 2005 Mercury Grand Marquis. The contact stated that while parked, the headlights would not illuminate. The contact was able to activate the high beam headlights by holding the turn signal bar. The low beam headlights illuminated intermittently. The vehicle was taken to an independent mechanic for a diagnostic test. The mechanic stated that the headlight control module would have to be replaced. The vehicle was not repaired. The approximate failure mileage was 72,800.

Headlights fail to come on or suddenly shut off while driving. Other lights, interior and exterior function. Headlights will burn only if the turn signal lever is held back. This is an extremely dangerous malfunction that is being experienced by many Ford crown victoria and Mercury Grand Marquis owners, model years 2004-2005. Dealers will replace light control module for $500 with no guarantee it will fix the problem. I know of several Ford owners with the same identical problem. Many wrecking yards are sold out of the salvaged lcms (doesn't fix the problem anyway. ).

The contact owns a 2005 Mercury Grand Marquis. The contact stated that the headlights and high beam headlights failed without warning. The contact went to try the lights two hours after the failure and the lights did illuminate, but failed shortly thereafter. The vehicle was taken to the dealer where the contact was told that there was short in the lever used for the turn signal and the lights. The vehicle was not repaired. The failure and current mileages were 96,000.

While driving at night, my wife put on the left turn signal and the headlights immediately failed, creating a dangerous situation. She frantically fiddled with various light controls until finally discovering that by manually holding the "flash to pass" high beam lever, it brought the headlights on allowing her to make it home. The headlights were checked by the Ford dealer on August 5, 2011. Tests revealed no cause but the mechanic suspected the light control module. He advised further driving, which I did that same evening only to experience repeated headlight failure when using either turn signal or activating the high beams. Then I discovered a number of internet postings in which drivers experienced the same problem with Grand Marquis' or Ford crown victorias made in the 2000's. Then I found a website which stated that the original light control module had a major problem involving a bad circuit that is the definitive cause of the problem. The local Ford dealer acknowledged awareness of the problem (even citing several crown victoria police interceptors that required lcm replacement), but because Ford has not issued a recall, they wanted over $1,000 for diagnosis, part, and labor. A website also noted that Ford recently completely revised the lcm with an internal redesign by Ford engineers so that the new lcms will never fail. The website also noted that some dealers continue to sell the old defective lcm which will only fail again. My opinion: besides not wanting to pay an exhorbitant amount to replace one component of a vehicle's light system, it appears Ford is fully aware of a potentially deadly defect affecting many thousands of Grand Marquis' and crown victorias currently in use, but has not issued a recall. This potentially deadly defect must be addressed! it is entirely possible fatal accidents have already occurred but were misattributed.

I was driving on I-81 at night, I operated my left turn signal while accelerating to about 75 mph to pass a truck and my headlights went out. I accidently forced the high beam on by flipping the turn/high beam lever and I held the lever in that position until I could return to the right lane behind the truck and stop on the roadside. To say I thought I was going to die is not simply drama. The worst part was not knowing if my brake lights were working. While off the road, I could not duplicate the failure. I put on the low beam and proceeded on I-81. After some miles, I again tried the left turn signal and again the lights went out. This time I was ready, and used the high beam lever to get to the roadside. Again I could not duplicate the failure. I exited as soon as possible, running on low beam, and the lights went out again on the ramp when I operated the left turn signal. I continued to ocala by way of atlanta, running in daylight only. I took the car to ocala Ford as soon as I arrived in ocala. The dealer had the car several days and finally duplicated the failure. They replaced a module at the cost of $786. 00 and said the car was safe to drive. No repair was done to the turn signal. I got the module from the dealer and sent it to NHTSA for testing to determine if it actually was defective. If not, then my car presents a risk to everyone sharing the highway with me at night, because the problem would still be there. In my opinion, sudden and catastrophic failure such as this presents fatal risk to anyone involved in a crash, including the general public. This failure has nothing to do with reasonable wear and tear, it is a design/manufacturing defect, worsened by a failure by Ford to provide a diagnostic program. Since the problem is intermittent, people may have already died and no trace of the failure would be found by examining the wreck. Updated 01/19/11/ updated 01/20/11.

2005 Mercury Grand Marquis 85,000 miles, headlights go out at any speed when hitting a bump or pot hole. No high beam or low beams but flash to pass will light both high and low if turn signal arm is held back.
