WeAreTwoDoorsDown: That's actually a really good soldering job (especially with that crappy iron)! You just need to scrub that brown stuff off with water or rubbing alcohol. That is the flux residue, and it's usually harmless but sometimes can eat the circuit board. Most modern solder doesn't do that though, so no need to worry.
Kwame Martin: SOMTHINGS WRONG WITH THE NEW PART NUMBER, I GOT THE WRONG ONES. IVE CHECK AND DOUBLE CHECK THE NUMBERS. MINE ARE TOO SMALL AND THE PIN DONT ALIGN.
Len B: Thanks for the informative video. I did mine 2 weeks ago. Not that I had a problem but being proactive. I am glad I did because after I cut open the relays, two were really bad. A problem waiting to happen. Keep up the great work!
Lloyd Hanson (Paparaptor): Thanks for the video! PIcked up a unit from a 2005 Crown Vic to replace the one on my 2003 Grand Marquis and wouldn't you know it... The module from the Vic has the same problem. Checked the odometer and the taxi was just a tad over 300k. Plan B). I pulled the cover off my old module, which was intermittent and plugged it back in the car. Decided that the top left relay (oriented with the connectors on top) was the one failing and removed one of the relays out of the donor box (definitely not the top left one) and put it on my original. Works perfectly, but I ordered 8 new relays so I can replace them on both modules. It's less hassle than leaving it at the Ford dealer for a day.
Stephen Portz: Does anyone know which relays control which services in the car. The dome lights, hazards, and turn signals don't work but lights and dash do. Be nice to not "fix" the part that isn't broken. Thanks.
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.
David Kriner: Mouser has added a 653 to the beginning of the part#.
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.
hddm3: wait that said made in mexico on the bottle. wtf
Maria Smith: There is a 21 week backorder on the parts. Anyone found another source?
ventureelect: Always heat the pin and the circuit board equally (then apply your solder) in order to avoid cold solder joints.
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 before mine)
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.
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!
mike m: Have you ever fixed a GEM module on a 1998 f250 ford or is it not possible
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.
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 champ.
elppedro77: Outstanding video!! Thank you beltstowing! I will order the relays and fix it myself, saving me about $280
dasmanal mcclinton: Has anybody else made a mistake and burn't a copper trace?
