Could be low beam relay , did you check it ? The relay is located in the fuse / relay box under the hood in engine compartment . Do you know how to test relay an power an control for the relay ?

SOURCE: low beams not working on 2007 dodge ram 1500
a possibility is the multifunction switch or the tipm being bad. check the wt/lg wire in the left headlamp assembly and the wt/tan wire in the right assembly for power

maybe a fuse the fuse box is under the drivers side passenger seat . sometimes ive seem them get something spilled on them and i had to wiggle the fuses to clear the corrosion

The relay under the hood may have gone out. We had the same problem on our 2007 Buick LaCrosse CX. The bulbs were fine, high beams worked, all turn signals and everything except the low beams turned on. Turns out the relay had gone bad.

Possible relay fault,also a burnt dimmer switch will cause this symptom
Shannon, you did not state if you checked for voltage at the fuse location-or better yet at the bulb location-
If a connection at the relay that feeds power to the low beams has come loose, then the low beams will stay out. Suggest that you locate the headlight relay (in a box under the hood) and verify that it is operating. If an assistant can operate the headlights while you listen (and feel) for relay operation, then you can eliminate that as an issue. Next would be the output of the relay (contacts could be bad) - and if you cannot open the relay to verify good contacts, then purchase a replacement relay (possibly from a junkyard) and plug that in.
Remember, the relay supplies the power to the headlights.
