2004 Dodge Ram 2500 diesel. Right low beam not working. High beam works fine. Tried several different bulbs. No power at bulb plug end for low beam.

SOURCE: Right headlamp doesn't work on low beam only

in this case make sure you have voltage going to the low beam lights. 12 volts. you need a volt meter. if you do not have volatge you have to check and make sure power is going through the fuse. a bad fuse will be broke, but you can have a good fuse with no power going through it. if you have power going through the fuse you have a wiring open somewhere between fuse and whatever is between the headlight connecter.

plz check and get back i will keep checking on here on and off.

SOURCE: left low beam is out on my 2006 dodge ram 1500 4.7

I'd still vote for the bulb being bad. The high and low beams use two different filaments, so unless the bulb is physically broken, it is common for the low beam to be bad whilst the high beam is good.

That's why you see some people driving around with their high beams on -- they don't want to get stopped for a 'light out' citation..

When you take the bulb out to replace it, be sure to look at how it is mounted before removing. You don't want to accidently adjust your headling out of kilter.

good luck

SOURCE: low beam headlamps not working bulbs ok dodge ram

I replaced the dimmer switch on mine & it didn't fix it.

SOURCE: I have a 2004 dodge

The Front Control Module is attached to the under hood fuse block with 4 screws, The FCM is the power supply to the headlamps, if all other lamps are working correctly the concern is most likely caused by a defective FCM. Verify the WT/DB wire, left low beam driver is good. If it is replace the FCM. you can use a FCM from a salvage yard, these modules do not need to be programmed for your vehicle.
