Low beam headlights not working.

[jakjacbunce]

Hello everyone,
Hoping I can get some help.
My 2019 Ram 1500 Big Horn is having issues with the headlights.

The fog lights come on and the marker lights but not my low beam lights. The high beams still work.

Any ideas on where to start.
I’m not seeing a fuse related to low beam headlights.

My headlight switch did fall out of the dash and came apart but I put it back together,
Possibly something is there isn’t right?

I see that I can buy a new headlight switch assembly on RockAuto for $32.

It sounds very likely it is the switch.

Get a new switch, that should take care of it.

Maybe the headlights are controlled by the BCM. Can you disconnect the battery for awhile to see if that helps?

Otherwise there may be a relay involved. Can you provide info about your truck too? Make a signature with details. Do you have halogen or LEDs?

I have to ask, have you checked the bulbs?

Base and premium lights are both controlled by the BCM.
I guess it is possible to have both low beams burn out lol.

Base.


Premium.

Does the BCM engage a relay for the low beams too?

No relays, the lights are driven directly by the BCM.

Hard to tell from the pic, but it goes from the BCM to a circuit board before hitting the lights?

Yes, that is with the premium lights.

Mines doing the same thing everything works except dim lights. I have not check the bulbs yet tho. I had read somewhere that the back window leak could cause a problem with headlights.
