    Just picked this truck up a couple weeks ago.
    Since I got it the headlights have been a little finicky (mostly very dim headlights, passenger side headlight being much dimmer then driver side even when swapping bulbs from driver side) and also the "brights" indicator on the dash comes on/off dimly while driving with the lights on

    Here's the new issue. It's been raining all day here in florida, drove home from work with the lights on, turned them off and parked it.

    Came back out an hour+ later and saw they were still on?!?
    Jump in the truck and see the light switch was off, started the truck up and let it charge for a few minutes.
    Turned the light switch on and off a million times-when you flick them on they get a bit brighter, turn them "off" and they get a little dimmer but stay on.
    Also-when you turn the switch off the brights dash light comes on dimly.
    Also when the headlight switch is turned off, the rear lights turn off, just the headlights stay on

    So I started googling and tried to trouble shoot-pulled the headlight/dimmer switch and disconnected it-lights still on.
    Pull the steering wheel cover off and disconnect the multi function switch (had to remove a small 8mm bolt holding the connector on)
    STILL ON!!!

    Read about a front control module but not sure where that is or how to test it?
    Also read about a drl but I'm 99% sure my truck doesn't have one.



    But after sitting and cursing on my truck for a while they randomly turn off (after a million times starting/shutting off the truck ad flipping the lights on/off.

    But now I'm paranoid ill have a dead battery in the morning.
    Here's the funny part-three days ago when I left to leave work my truck was dead, brought it to autozone and got the battery tested-bad. Replaced it with a new one. It was probably the damn headlights staying on that killed the old battery!

    Someone please help me!

    This happens to me sometimes too....

    I just flip the switch back and forth a bunch, and eventually they go off... lol

    Except I was out there for about an hour.
    I don't want to do that ritual every time I use my headlights :suicide:

    I'm out of ideas now though. I was hoping for something easier like the switch or multi function switch but apparently its not.

    Welcome to RF!

    Here is a pix of the DRL Module, if you have one unplug it.

    Checked and didn't see one of those under my hood.
    Also I assume If I did have one my lights would have been coming on when I turned the truck on? Which they didn't do before.


    Googling I couldn't find a "front control module" for my 2001 dodge ram 2500 5.9l gasser. Don't think it has one after all.

    I'm completely lost now...

    What is a front control module?

    Here is the part number for the factory DRL module for a 2001 ram 56021561AC. In the 2001 FSM it goes over the headlight system starts on page 614 you might check it out.

    No idea what the front control module is-just read on other forums that that could be the problem (I've been googling this for hours now..)

    Unfortunately I don't have a fsm.

    ***edit

    I don't have a drl on my truck.

    Thanks for the link! Great to have a manual.

    But after skimming through that-only troubleshooting liste is the drl which I don't have.

    Trying to figure out these wiring diagrams and which one applies to me-still not 100% sure what's what.
    But looks like I just have the headlight switch, multi function switch and a security relay (which I Havnt checked yet)
    Hopefully (doubtfully) the problems lies in the security relay...
    But now I'm leaning towards a melted cluster of wires somewhere along the line....
    Other then that I'm out of things to really look for

    Headlight switch's do overheat, I'd start there.
