Headlight question 69 Dart340

[Darius]

My low beams will not light up but the high beams will. It just happened, one minute they worked the next they did not.
I tried changing the hi beam switch and that did not fix the problem.
Is/are there separate grounds for the low and hi beam??
Any ideas where to start looking? This is an original factory harness.
Thanks for the input

Might sound too simple, but it's happened to me. Maybe both lo beams are burnt out? Try different bulbs.

And if that doesn't work, check to see if all the wires are pushed onto the headlight switch correctly. Sometimes the wires can come loose from the shell and not make contact to the switch.

I've seen that before too. Driver didn't realize the right was blown out until the left one blew.
I've seen the connector behind the left bulb fail also. Both are tied together at that connector.
