    Helped trace the problem perfectly. Wish there wasn't any background music. Thank you
  • Thank you for this video! I’ve been watching other videos and skipped this one then finally watched it and it fixed my issue. My lights were not working correctly and I tried replacing fuse box and checking wiring and everything else you can think of excluding changing the FCM. After watching your video, I said screw it and went to a junk yard for 50 dollar fcm. It WORKED! Thanks again 🙏 it was for 2002 dodge Ram 1500.

    Excellent post. My lights are acting up. Thanks to your post I can go check some things that might be casing problems.

    My markerlights, taillights and fog lights stay on when I turn my truck off, and usually turn off 10 minutes later but sometimes stay on indefinitely. I'll definitely check this module

    FYI. I found on a thread that unplugging the fcm for 10 min can reset the tripped relay. Did all your tests and plugged it back in to jump wires and the lights can’t back on. With a new bulb. Power was not there before!!!!

    I removed the fuse box to access the fcm and with the lights in the on position I loosened the screws and started pulling on the fcm and the light turned on so then I put a couple more washers behind each screw and put it back together. Both lights are working and no longer have the "lamp out" message. I'll come back and edit if I have any issues.

    test lights are not always a good indication of a fault power feed wire. I have seen power feeds light up a test light but if that test light were able to put more of a load on power feed then it could show if it fails under a load. Did you happen to take apart the FCM? I am debating on taking mine apart and seeing if I can find a broken solder joint.
  • My 02 blew a trace in the fusebox. I ended up just soldering jumpers wires and reflowing the joints while i was in there lol

    Seeing this vid in 2024 finally taking up the task of finding out why my light is out. Tried the test and got to the post where you made your headlights flash and mine did not. Any help would be great! Thanks
  • @MrDogmeat1
    was cheaper to replace or you think better just to send it out to the companies that fix circuit boards? Like pcu's or ecm's
  • Great vid... have a question....I have an 05 2500...my marker lights ..roof lights dont come on...everything else does...did a jumper from pin 15 on Fcm to 73 fuse which is parking lamp fuse...and worked for years ...and now it crapped out...check and found jumper wire corroded..replaced it have power going to 73 fuse and it didnt work...fuse circuit board issue?..
  • Any assistance would be nice on this. I have an 04 ram 1500 hemi and one day all of a sudden my front right low beam went out. It's one whole bulb system and I replaced the bulb but it didn't work. Then I fiddled around with a couple fuses for the FCM relay and all of a sudden it came back. But after driving a little while it basically shorted itself out again. Both the old and new bulbs are fine.
  • @Mackahroney
    Do you have led bulbs for your lights? If so, are they connected to a resistor?
  • @TheMatrixgod
    does the front control module also control the blonkers?my truck the headlights,one works regular the other is high beams but if i swamp the bulbs same thing happens and also the blinker lights dont work,
  • @jayhopkins1337
    Was the problem low beam only? Or high beams also? Both my lows out now. But highs work
