Question about 2005 Mercury Grand Marquis
THIS IS ON MY 2005 MERCURY GRAND MARQUIS GS. THE LIGHT CONTROL MODULE FAILED AND MY HEADLIGHTS WENT OUT AFTER DRIVING THE VEHICLE FOR 5 TO 10 MINUTES. THEY CONTINUE TO DO THIS UNTIL THE SYSTEM WOULD COOL DOWN AND RESET ITSELF, TAKING 15 TO 30 SECONDS. I HAVE BEEN TOLD I NEED TO HAVE THE LCM REPLACED COSTING OVER $500.00 FOR JUST THE PART. THE MECHANIC STATED THAT WHEN HE CALLED THE DEALER THEY STATED THAT THEY ALWAYS KEEP THEM IN STOCK BECAUSE THIS IS A COMMON PROBLEM. MY QUESTION IS WHY IS THIS NOT A RECALL ITEM??? THE HEADLIGHTS GOING OUT WHILE DRIVING DOWN THE ROAD AT NIGHT MUST BE A SAFETY ISSUE?
I've read a number of LCM posts for Grand Marqius. Repairing them is all the buzz on Ebay --- pay $50+ and various vendors will "replace" 4 relays on one of the boards in the LCM. Don't open the box though, because doing so will void the "lifetime" warranty for the fix. Here is what I found when mine went bad. The specs on the NEC relays indicates that their service life is a bazillion operations before failure. They can be had off the internet for about $6 a piece. Of course, why replace one if you already have the unit out and opened (that is if you could determine which individual one has failed). I recalled reading somewhere in my research of this problem that a cause of this LCM failure was a soldering problem on the boards during manufacture. My brother-in-law used to fix TV's and we discussed the issue. We looked at the relays on the board and found micro fractures along the edges of the solder where the relay pins extend through the circuit boards. We heated the pins to melt the existing solder and added more solder to the 20 pins on the board. Problem solved!!! LCM works great. No more headlight failure. No replacement parts! I'd strongly suggest you attempt this fix before sending your unit out or exchanging it

I had same problem, this is a very common problem on Gran M. If you go to ebay you will find companies that you can mail your LCM to them and they will repair it with a life time warranty for as cheap as $50 bucks. They even pay for return shipping and the turnaround is about a week!
Ford makes a lot of money on replacing this part, why would they recall it? By the way, normally your headlights will still work when they go out if you manually hold back the bright lever on left of the steering wheel shaft. ( Like you were going to flick you brights at another car.) This will at least get you home or to an exit...

Because usually someone has to be killed or cost a million dollars to go onto a recall

If the high and low beams do not come on, yet the lights do energize when you hold the "flash to pass" lever towards you, then it probably is the LCM (Light Control Module...) And there is now VERY GOOD NEWS!!! Ford just started fixing them for FREE!!! (Ref: Ford Customer Satisfaction Program 14N01) Ford/Lincoln/Mercury has finally decided to deal with the rat-nasty LCM's they have been putting out. I just got the letter on this from Ford last week. Without starting a safety recall, (as they should,) they are extending the warranty on the LCM (based upon VIN number,) to 15 years or 250,000 miles whichever comes first. AND if you paid earlier for this replacement and have the receipt, they will REIMBURSE you for the repair provided it was done before the notice came out. The window to be reimbursed for an earlier repair looks to be between April 1st, 2014 to October 31st, 2014. This window also applies if your car is under 15 years, yet has exceeded 250,000 miles. Ford's LCM replacement is completely without charge for parts and labor. Retail owners should have their VIN number handy and call the local Ford/Lincoln/Mercury dealership for an appointment. They say it should take a half a day yet could be longer due to dealer "service scheduling requirements." They will only replace LCM's that do not work, but mine lasted 10 years before it started acting up. This gives Ford a way to show concern, without really dealing with the 1000's of LCM's that will fail after this window closes in the future. Ford only "invented" their LCM after their service departments were losing money on a system that smaller repair shops could easily fix. Nice to have a little black box that they could unplug and swap out so they could charge $800-$1000 in parts and labor then repair at the factory with three $10 relays. Anyway if you have any questions about this "un- recall" you may contact the Ford Customer Relationship (I'm in a "relationship?") Center at 1 (866) 436-7332 either they or the dealer can tell if your vehicle is covered if you have the VIN number handy. IN THE MEANTIME. Should you need to get granny to the hospital at night, you can try this AT YOUR OWN RISK. The LCM on my 2003 is located about 18" directly above the gas pedal under the back of the dash... Turn on the lights and give the LCM a tap with your foot. This will often engage the cheap Ford relays and the lights will come on. But you should make that appointment with the dealer before everybody starts fighting for access to the same part. I also don't know if Ford would be willing to call someone a liar if he claimed his headlights stopped working because he thought it is just a matter of time before the lousy relays in his LCM failed, since this is intermittent, and asked for an LCM replacement under this warranty as well. That is why this should be a RECALL, and not just some bean-counter's way of slithering out from all of the angry customers that demand action today. My Grand Marquis is really a fantastic car, but having to drive 50 miles home on narrow country roads with one terrified hand while holding the "flash to pass" arm with the other, and risking my life because Ford played it cheap with some relays on their flagship chassis for a decade or more, really makes you wonder what they were thinking.Remember: you have to take your car to a DEALERSHIP to get this fixed for free under warranty. DO NOT TAKE IT TO A PRIVATE REPAIR SHOP unless you just want to throw your money away!
