Donald Thompson: I wish i had brought my 2004 Mercury Grand Marquis back to the dealer and
paid the $800 dollars to fix the headlight issue properly. Instead i went
and bought this Dorman LCM Bypass Module and put it in according to the
manufacturers instructions, it caused an electrical failure in the cars
fuel system and it wont start, i took the module out and it still wont
start, so now the car is worthless and will probably be destined for the
crusher. The damn bypass module wrecked a perfectly fine car.
Ross Rogers: If you don't mind what is the fit like on the newer part # you listed? I
call Mouser and tried to order the # on your invoice first. The sales
person even got an engineer on the phone that stated the part was obsolete
and that there wasn't a suitable alternative. I saw the additional part
# you supplied and ordered a few of them I was just curios how close the
new # is in fit and function when compared to the old one. It also seems a
little disheartening that if they are close that the engineer would have
withheld that information.
Daves Marauder: So I get a letter from Ford this week. Seems there is enough of a problem
with this, they are extending warranties on the LCM for a number of
vehicles. My letter said they would warranty the LCM for 15 years or 250k
miles(my car is an '03 Marauder). It even seemed to suggest it was
transferable if you had sold the car to someone else.
Any other owners get one of these letters?
(oops, had comments sorted wrong, didn't see sitandbull210's post right
Maria Smith: There is a 21 week backorder on the parts. Anyone found another source?
Wero Montiel: Hi, I have a grand marquis 99 with light control module issue, after the
heavy winter we had, my car battery was killed a couple time(I thought it
was due the winter) but my mechanic found the light control module has a
short circuit, do you think this will be fixed if I change the relay? I
guess the relays are circuit shorted and stay open and kills my battery
tho, what do you think?. Thanks in advance!
hddm3: wait that said made in mexico on the bottle. wtf
David Kriner: Mouser has added a 653 to the beginning of the part#.
ventureelect: Always heat the pin and the circuit board equally (then apply your
solder) in order to avoid cold solder joints.
mike m: Have you ever fixed a GEM module on a 1998 f250 ford or is it not possible
Ryan Smith: Here is the link:
it is the same part number just sold in white and made by a different
Francisco Moreno: great video and what a money saver.. I see you're with PBC, you're
probably a tech there or mechanic? Anyhow, thanks for the video..
william abair: I have a 2008 F-150 and am experiencing problems with my auto lamp. Im also
having problems with interior lights and auto locks as well. Will this fix
take care of my problem? I fried a wiring harness prior to problem.
elppedro77: Outstanding video!! Thank you beltstowing! I will order the relays and fix
it myself, saving me about $280
sitandbull210: Hello everyone...just wanted to let everyone know that Ford finally put out
a recall on the LCMs...got my letter today 4/28/14...just 2 days after I
fixed the darn thing myself.
Ryan Smith: Just as a heads up to anyone that orders these relay's, they are now white
and made by OMRON. Thanks for the vid, just did mine and it works like a
dasmanal mcclinton: Has anybody else made a mistake and burn't a copper trace?
Robert Browder: I just replaced the relays in the LCM for my 2003 Mercury Grand Marquis.
It took about 2 hours and the hardest part (for me) was getting the box out
from, and installed back under the dash.
The local dealer wanted $610 to replace the LCM.
This video saved me a lot of money
Angel Delgadillo: I have a check engine light issue and trying to get the dashboard off to
change light bulb , can you give me any advice on how to remove the
s webb: Hey do you know if the air bag warning chime is in the LCM and can i remove
the chime? Thanks in advance!
gotmituns: anyway, i finally had time to install the 4 relays into my light module
crown vic, while following instructions. took about 1 hour. it is a very
easy task, instead of spending hundreds of dollars. the lights work. my
previous symptoms were, I heard a click in module and the headlights went
out. then click again, and the lights came back on. i had to hold the high
beam in order to have headlights at all times...
grandmercls: Awesome video! I drive a 2004 Grand Marquis, with the same issue of
headlights turning off. Now they don't turn on at all, period. Can this be
fixed by the same process you are showing? Also if i put the original light
bulbs back in after this rebuild, will this issue go away?
jdmsir231: great video thanks for posting, mouser no longer has the nec 511-eq1-11111s
relay is there an alternate?@beltstowing
towrecker: then you have the hot switched lights , not relay controlled , and no you
can't take it out , it will if I remember right kill the dash light circuit
...was this car an ex police car ? and are you sure something is not tapped
into one of the wires to the wiper delay controller , as that's what you
said was clicking , a dropped voltage , or ground will cause relays to go
towrecker: but they do go through the " multi function switch" better known as the
turn signal , wiper , washer , high beam switch , they do go bad , they are
not cheap , so check all the other stuff I mentioned first by the way ,
there are only 3 lights , if optioned, that are not run through the LCM
they are , the pillar mounted spot light , the aux interior light "ticket
light" and the brake lights ...
towrecker: it's your call whatever you wanna do ...
ryan12689: I plan to go a different route with my LCM repair. I was going to solder a
5 pin relay socket onto the board, and make the relays external.
Steven Baker: I forgot to mention that All other lights work fine except the back-up
gotmituns: I think the switch is ok. But there is a black box under the steering
wheel, when the light turn off, I have to kick the box with my right foot.
Then I hear a click, and lights turns on. could it be a relay problem shown
in the video? (crown victoria 2003) thanks
roltyd22: The solder on the board doesn't look like it's ever been redone,but i could
Jon B.: I dropped my soldering iron one time and did the samething you did. Grabbed
it by the hot tip. It still goes on the floor because that hurts!
roltyd22: i googled the #,it's a dam wiper comtrol module.
Daves Marauder: I have a similar concern as Thor Jensen asked below. Can anyone confirm for
sure that the new Omron G5LE-1-E-DC12 part is sufficient in terms of the
current it can carry? I'm not a relay expert, but compared the data sheet
for this component and the original NEC EQ1-11111S. The Original lists 30A
contact current, the new part lists 16 A at 250VAC. With all the concerns
that even the original was under-size for the job, I wanted to ask for
opinions before replacing these. Thanks!
towrecker: no , it has no computer parts , it is just a big fancy switch , that's the
best way to put it in simple english lol
roltyd22: why would that be clicking and going nuts when the lights are acting up?
towrecker: and I will try and see if I can get a good cross on the number to make
double sure you don't have some weird ass oddball one lol
Thor Jensen: Yeah, I've seen a few of those external mods, but I don't like anything
that doesn't look at least factory'ish lol. Although having a socket would
be nice if it ever needs to be changed again. There's actually another vid
on here an amigo did with a relay from Advance Auto that he tucked up
inside the box and resulted in a nice, clean looking repair.
towrecker: belts towing gmail
roltyd22: F3LF-17D539-AA # ON BOX
towrecker: excuse me , I am not a damn tweaker , or junked out as you say , but I will
inform you that I am a freakING HILLBILLY , that owns a GUN , so go hide
Robert Lichtscheidl: Sorry about that. Mouser gave me the wrong relay number. The ones I put in
my LCM were EQ1-22111S which is supposed to be a direct replacement of the
ones you bought. $2.28 each. As I mentioned it fixed the light problem but
now my turn signals don't work and won't light in the dash. My dad has an
extra LCM from a 04 Grand Mar. and I will install the new (used) box
instead of re-repairing mine. Bummer my worked ended in more problems.
towrecker: the highest load on the LCM is 14 amps , that being your high beams , all
the others are far less , also remember the switch made by the relay is of
a ground , that helps some , also in dc that relay would be rated far
higher at just 12 volts , in other words , stuff them in , buy an extra set
for the glovebox , and never look back ,I could toss some algebraic
equations in here to nail it down to the exact rating , but it's pointless
, as those will handle at least what the original ones did...
sexychocalate1982: lol i looked its still there
towrecker: yeah the same thing , and unless you have a light staying on somewhere ,
it's not the LCM that is your issue ...
Ridge97: just think how many people would replace the whole box...good video jason
towrecker: do those pin out right ? the superceeded part seems to have enough rating
to make a good alternative , fill me in buddy if ya would , so I can
annotate my video here , I still have a pile of the exact relays laying
here , when mouser put them on the discontinued list , I bought all they
had left ;)
gotmituns: I have a problem with my headlights. when i turn the switch on, the
headlights will not turn on. I have to kick (lightly) the box with my right
foot, and then I hear the click, and the headlights turn on. But it is
annoying because when I use the turning signal, the headlights turn off
sometimes. Also they turn off while I am driving at night, and then turn
back on by themselves. is it module problem?
towrecker: if you have the plastic switch , replace it , ford recalled that design ...
towrecker: the damn auto lamp , never thought about that , you can crap can the relay
for it , and forget you ever had it , I do know that , the photo cell in
the dash has went bad I would bet money , hell you got an easy fix it
sounds like then ;)
SuperElgordo1: What are thoughs four parts to order off of mouser.com
Thor Jensen: Any update on this? I'd like a solid verification before I delve into this.
