      Informative posts on this board have recently helped me to perform an easy fix on my 1997 Eddie Bauer.

      A couple of weeks ago, my wife and I thought that the driver's side low beam headlight filament had burned out, because the low beam light would not come on and the message center gave us the "CHECK HEAD LAMPS" message. So I dutifully went to Advance Auto Parts and bought a new set of headlights, and proceeded to replace the current bulbs with the new ones. Only, the new driver's side bulb didn't correct the problem! After switching the positions of the bulbs, however, I was able to verify that neither the new nor the old bulbs had actaully been burned out--instead, it was as if the driver's side headlight was simply not getting power in the low beam mode.

      After doing a search on this forum and the 1995-2001 Explorer forums and looking at a number of posts dealing with the "Lamps Out Module" or the LOM--many of which had been posted by other 1997 Eddie Bauer owners--I quickly suspected that my LOM was malfunctioning. Sure enough, after looking at it, I noticed that one of the solders where the female end of the wiring harness pins were connected to the LOM circuit board had fractured. I took out the soldering iron and re-soldered that pin to the circuit board, re-installed the LOM in its protective casing, re-connected the message center computer and reassembled the center console, and the driver's side low beam worked again!!

      Very quick fix, and very easy to do as long as the re-soldering is carried out carefully. Total time to fix was less than 30 minutes. Anyone else having this problem with their 1995-2001 Explorers, just search the Forums for posts dealing with "LOM" or "Lamp Out Module" and you'll find plenty of info on how to get at the LOM and how to fix it.

      Just thought I'd share the good results. Thanks to all those other second gen Explorer owners who posted about this problem and how to fix it!:thumbsup:

      Lom...

      I have the same problem with the d.s. low beam on my 1996 E.B. Explorer. I even went to the same store and went through the same routine with the lamps. Anyway, I will be pulling out the LOM and inspect it for bad solder joints. I accessed that area last week and tried using a multi-meter on it. I am not too strong with my electrical troubleshooting abilities, so I am definitely going to try a visual. Hopefully, I will have the same luck you did. Thanks for your description of the fix, I am sure it will help.

      Anyone know of a schematic for this module???

      LOM Fixed...

      Thanks to all who posted their info about this problem. I repaired my LOM in a matter of less than 30 minutes, that includes re-installation. I had a similar problem with my left side low-beam not working on my '96 Explorer, E.B. I went through the typical routine of swapping and changing lamps, and checking fuses a few weeks ago without any success.

      I figure it was a good time to look into this matter deeper since it is snowing like crazy outside. After reading some posts in this particular thread a few days ago, I finally decided to remove and do an inspection of the LOM using my magnifying glass w/light. I quickly, and I do mean quickly, found a slight brown spot on the backside of the board. I then looked at the solder joint of that particular area and found the solder had given way 360 degrees from the pin. I carefully re-soldered the area and re-installed the LOM.

      Everything works great and it saved me about 70 dollars. Nice timing, because Christmas is here and I haven't finished spending money on the wife!!! ;)

      Thank you all and Happy Holidays.

      I had the same symptoms on my 1995 Limiited. The passenger low beam would not turn ON. I removed the LOM, inspected it, and immediately noticed that a through-hole solder point leading from the harness connector to the board was burnt through. This type of damage only happens when too much current is run through the connection, therefore heating up the soldered connection to a point that it melts/burns away. I resoldered the connection, reinstalled the LOM, and the passenger low beam works now. Thanks for leading me in the right direction. I had already rebuilt the driving lights selector switch and turn signal/high/low beam switch.

      Just want to thank everyone that contributed to the "right headlight out" threads. I had the problem in my '97 Eddie Bauer and my Chilton's didn't have a diagram showing the LOM. With your help, the problem was solved in about 20 minutes.
      Thanks again,

      FIXED! The lamp out module connector was a little loose. I just pressed it in after accessing, and the low beams came on. I'm going to see how it goes, or if something doesn't need to be done to keep it working.

      Hi Jflorida.
      Just get your fingernails under the console trim edge and pull up. The whole thing comes out in your hands. The LOM module is on the passenger side in the console, held in by two screws..need a short phillips screwdriver. Don't drop the screws, they can be difficult to find.

      Thanks!

      You guys are awesome for posting this fix. I, like most of you, went on the rabbit trail of replacing bulbs, checking fuses, switching bulbs, switching fuses, replacing multi switch (needed it anyway). Sure enough, the LOM just needed a little solder. Voila. Hardest part of the fix was those stupid little screws holding the LOM to the console.

      Worked for me as well, Thanks Guys

      OK, couldn't wait so I put a heater in the truck, ran a trouble light out, pulled the console apart and took out the LOM just like you all told me to. Pulled it apart. found two pins that the soldier looked a little iffy on so I resoldiered them and put it back into the 85 exploder. IT WORKS! Both Headlights back on, no more warning and fog lights work again! Thanks to all of you.

      LOL, only on Explorer forum. I was thinking this over at 11:30PM, snowing out, which rare for this part of Canada (SERIOUSLY, 4mm is actually rare in Vancouver this year, it'll be gone in two days though), and I figure 'what the hell, the bulb didn't work, the Ford service manual says check the LOM pinout for continuity...hmmm.' Threw on shoes and now it's 12:01AM, my low beams work, my FOG light started working and , as Tbar4 said, I'm walking around with that grin now. Oh how I thank thee, let me count the money saved!

      Only on Explorer Forum...wow, my hat is tipped, my glass is raised!

      Fixed LOM

      Great info I spent hours tring to fix the issue till I found this thread. I found the LOM and indeed it was burnt. I soldered the unit and reinstalled and only my driver's side headlamp illuminated. Dissapointing. I found out after I bought it that someone had spliced the passenger side lamp's power into the driver's side. I assume he didn't find this site. :) Anyhow I reattached the drivers headlamp and now it works. Passenger doesn't any thoughts...

      Thanks to all

      I had the same problem on my '95 Eddie Bauer. After spending hours tracing and testing wires and connections, I was out of airspeed and altitude...then on a whim I googled the problem and you guys appeared (the internet is a wonderful thing). Just as suggested, it was a loose soldered connection on the circuit board in the "lamp outage module" inside the console. You folks saved my sanity! This website is going to the top of my "Favorites" as I plan on keeping this thing a long time. Thanks again.

      Just dealt with this last night and am trying to find the module online. And it's funny, I changed out my grille today and seen the wire spliced from passenger's side to driver's side.

      Please help

      Im having the same issue with my 1998 Explorer. The driver side low beam is out. I replaced the bulb and still, the low beam is out. I popped open the center console to check LOM and there isn't one there. I learned that they stopped putting them in these models. What do i do now? Also, i checked some fuses but not sure which fuse could be the culprit. I checked every fuse that had something to do with the headlamps. Please help. Thank you.

      Same problem and solution here. '97 Eddie showed all of the symptoms described. Removed module, could not detect any burnt solder connections. Re-attached connector plug and now working lights. I would try the connector jiggle before going after those pesky little screws

      I have an 1997 Limited 5.0 AWD Explorer with factory daytime running lights.

      My passenger headlight was not working on low beam...the fuses and the bulb were fine.

      Read this thread and fixed it! Thanks Explorer forums!

      How to:
      1. In the centre console remove the error message centre, it's just snapped in place, no screws. Careful use of a flat blade screwdriver will help. Leave the wires attached and place message centre towards the drivers side.
      2. On the passenger side of the inside of the console there is a black box (LOM) with a grey connector. At this time you can attempt a "wiggle test", in my case the passenger headlight came back on!
      3. Remove the LOM by removing two philips screws, one of them is very difficult to remove. A 90 degree ratcheting bit drive was very helpful.
      4. Disconnect connector.
      5. Carefully pop open the black box.
      6. Check for burnt circuits, I had NONE. However, looking at the top left of board (bottom side of the board). I found a very small crack in the solder joint for the connection for PIN 11.
      7. Complete the solder repair
      8. Re-install

      Passenger headlight works AND now my fog lights work too!

      Had the same problem about 3 years back and the same fix, AFTER I bought the new part from Ford. I installed the new piece and something wasn't working right with it ( can't remember what was wrong with the new part ) and a friend with good eyes looked at the old one and while I was fooling around with the new part, pulled out the soldering iron and fixed it. Still have the new ( and not cheap :mad: ) part sitting on the work bench with about 3 minutes of time used on it.

      Bumping this thread back up...my LOM went off the deep end. I chased after the MFS, because one light went out, and flicking the high beams on and off made it come back on...

      My 2 cents...I've owned my 97 Explorer since it was new...it's been a good machine!

      I have re-soldered the Driver Side pins twice in the past 5 years. This week the Passenger side headlamp went dead. Diagnosed the problem as being INSIDE the board (not solder joints this time). This vehicle is 18 years old. I don't need any stinking "headlamp out" warnings and don't want to buy a new board, so I soldered 2 jumpers to the board so I'll hopefully never have to deal with this again. Sorry i can't upload photos to this site...

      One jumper (a short piece of wire) is soldered to the back of the board to permanently connect pins 1 and 11 (Driver side) and the other is from pins 13 to 15.

      Only do this if you are ok with defeating the "headlamp out monitor"

      Now both headlamps work great. I hope I'll never have to mess with that board again!

      Another tip...to keep the screws from falling into the center console during re-install, use 2 thin cardboard nuts to hold the screws to the plastic housing...like the paper nuts on a residential light switch...I got the cardboard from the back of a paper notepad.

      GOOD LUCK!
