Try cleaning the plug at the Radiator Support. Unplug it and make sure there is a good connection

Headlight switch is ok if high beams work.Check the dimmer switch output to see if you have power coming out of the switch. Low beams will be the tan or brown wire. The green is high beams. The other wire is coming from the headlight switch to the dimmer switch.
If all checks good there, check both sides of firewall bulkhead connection, then out to the radiator support plug in.

Don't forget 'headlights 101'...........your low-beam elements could simply be burned out? Good luck.
