2001 ford focus low beam lights not working?

Low beam lights not working but my high beam lights work fine. What can be causing this? I checked the relays under the hood all 4 relays are good. Also checked fuses in car and those are good. Replaced malfuction switch that goes to steering columm and still the low beam light do not work also replaced head light bulbs. What else can it be? Can the head light switch that goes to dashboard be causing this i haven't replaced that yet but that is my next step. Any advice?

Try to check the headlight socket's if the low beam light wire / socket is still connected…

Check your fuses

I would go with that next too, but geez

Could be the multi function switch
