My first thought would be the dimmer switch. Have you checked for power in and out of the switch on the low beam setting ?

you have to remove the steering wheel and get inside the steering column

Go through all your fuses, Dim lights run on a separate fuse.
SOURCE: no power at fuse block for low beam head light
hello, the left and right headlight fuses are powered by the same circuit. the circuit is bus bar inside the fuse block. if you are 100 percent sure the fuse is dead, then the only possiblitie is a bad fuse block
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.
